How To Keep Ice Packs From Sweating? The 128 Correct Answer

An ice pack is essentially a product that mimics the standard characteristics of ice, except that it consists of a plastic bag containing ice. It has the same physical properties as ice, such as its coldness. However, it may differ slightly in functional properties. While the predominant use of plain ice cubes is to chill beverages. The benefits of an ice pack vary to serve different purposes. There are different types of ice packs or ice packs that are available. This includes using any plastic bag filled with ice. Many people also tend to use a bag of frozen peas as an ice pack. More recent innovative times came with the introduction of Ice Gel Packs and their wide spread among the population.

Difference between ice packs and ice gel packs

Simple ice packs consist of a plastic bag full of ice. An ice gel pack, on the other hand, is a plastic bag filled with special cooling gel. People consider these two items as cold packs. However, one may consider ice gel packs over the other. There are key differences that set the two apart. An Ice Gel Pack tries to improve on the characteristics of the typical ice pack.

How are gel packs made?

Ice gel can be made using many methods. Most of the time, the ice gels in ice packs are made of ammonium nitrate or urea. However, there are other techniques such as B. Rubbing alcohol. There are many tutorial videos online on how to make a homemade ice gel pack.

Benefits of using ice gel packs instead of just ice

The ice gel packs have certain benefits that make them a better option than just frozen water. Always look for one that will last longer at room temperature. Ice Gel Packs contain cooling gel. This gel is an additive-enriched liquid with a higher viscosity than pure water. The cold chain packaging industry benefits significantly from Ice Gel Packs. The reason for this is that the Ice Gel Packs stay frozen longer at room temperature than ice. Additionally, they also offer a better option than “wet ice,” which refers to blocks of ice that become wet from melting. Therefore, refrigerated packs prefer their food not to hit wet surfaces as this can affect food quality. For these reasons, Ice Gel Packs are an excellent alternative to blocks of ice in a plastic bag.

Various uses of cold packs

Aside from cold chain packaging, there are many other uses of the ice packs. An ice pack has several benefits as its functions range from cold retention to healing and pain relief. Many people also use ice packs in many healing treatments.

Medical Applications

Gel packs are ideal for treating common ailments such as bruises, pain or swelling. They are widely used in many medical facilities such as hospitals, clinics or nursing homes. In addition, it is also widely used in other institutions such as schools, army camps and offices as an aid to treat injuries. Medical workers, practitioners, and staff use ice packs for immediate pain relief and swelling prevention. The role of ice packs in relieving injury-related pain is beyond understanding. Therefore, ice packs serve an important medicinal purpose and have many medicinal benefits.

Ice treatment in orthopedics

Ice gel packs are excellent tools for performing ice therapy, an orthopedic treatment. Because ice gel packs can reach sub-freezing temperatures and last longer at room temperature, they are an excellent alternative for this treatment. Ice therapy, or cold therapy, involves rubbing ice-cold objects on the injured part of the body. When tissue damage occurs, the body triggers an inflammatory response that causes the specific area of ​​tissue damage to swell. The swelling makes the injury more vulnerable to further damage and slows the body’s healing process. Therefore, immediately applying an ice gel pack to an injury helps slow the inflammatory response, leading to swelling. It also speeds up the healing process and promotes the flow of nutrients to the damaged tissues. Ice packs are often used for acute or chronic injuries. Cover it with a cloth and apply it to the injured part of the body. If you are applying the ice pack to a recent injury, make sure the swelling is within the 48 hour time frame.

fitness and sports applications

Exercising involves cruel and strenuous exercise that causes fatigue. Fatigue and muscle pain, cramps or even injuries are common in fitness facilities, gyms and martial arts training centers. Like medical facilities, cold packs are finding their way into the fitness and sports industries. Some of the injuries that ice packs treat are very common among avid fitness and sports players. These include tendon and muscle damage, as well as multiple forms of bruising and swelling. Additionally, the fantastic pain relieving properties that comprise Ice Gel Packs make them an ideal treatment for professional athletes undergoing intense training such as bodybuilders, martial artists and soccer players.

food preservation

Finally, ice gel packs are incredibly important to the cold chain packaging industry. They are cornerstones for keeping heat-sensitive foods fresh in insulated containers for the shipping process. When transporting perishable goods such as fresh meat, eggs or other dairy products, ice gel packs are often used along with the packaging. In properly insulated containers, ice gel packs can retain their coldness for about 24-36 hours. As such, they are excellent as cold packs, slowing down bacterial growth in perishable goods.

Conclude

Ice packs are an excellent source of food convenience and preservation, and their benefits extend far beyond industrial use. They are a great thing to have in the home with several broad purposes.

Here are the best ice packs for coolers, based on our research and testing, so you can keep your food and drinks cold without the hassle of ice cubes.

But there’s plenty to choose from, so we’ve chosen six for our home tester to put them through their paces based on reviews and product information across a variety of brands. Our tester made note of how easy it was to store each ice pack in her freezer, how long it took to completely freeze, how well it fit in her cooler and/or lunch box, and most importantly, how long it kept them Food and drinks cold. In the end, the Arctic Ice Chillin’ Brew Series reusable ice pack won for its ability to keep our tester’s drinks and lunch cold in a hot car for four hours.

Most reusable ice packs are now gel based as these offer better cooling performance than frozen water. In combination with a suitable cooler, ice packs can keep the contents cold for days. Being able to freeze them for thousands of uses can also save you money in the long run.

Cool boxes don’t keep your food cool by themselves. You need the cooling power of ice to preserve perishable goods and keep drinks nice and cold. However, if you just throw in ice cubes, they just melt and make a watery mess. Luckily we have ice packs that you can easily store in your freezer.

She prepped her RITC cooler with the Yeti ice pack about 3 to 4 hours before use. “I was worried this would cause a melting problem when I needed the cooler, but it kept the [canine and human] ice cream products I put in perfectly cold,” she says. “I kept them in the cooler in my car in 75 degree weather for about an hour and when I got home they were perfectly intact, not frozen.

Each ice pack features a durable, shatterproof outer shell with a hole in the middle that reduces freezing time. Our tester’s 2-pound Yeti took about five to seven hours to fully freeze — close to the six to eight hours advertised by the brand. It’s also said to keep food chilled for over 24 hours, and while our tester didn’t wait that long, she was so impressed with the performance in her testing “experiment” that she’s still happy to recommend it for a day-long outing to keep items cold keep.

Yeti has made a name for itself as the go-to place for making durable mugs and coolers that can withstand the coldest and warmest of temperatures, and its ice packs are no exception. Although the ice packs are more expensive, they come in three sizes (1, 2, and 4 pounds), making them an excellent choice for small and large coolers. Also, it has a rectangular and flat shape that makes it easy to store in your freezer without taking up too much space.

Because the outer shell is plastic, simply clean the surface with soap and water before putting it back in the freezer. Overall we think this is a reliable and excellent option that will take the heat and keep drinks and food ice cold for a weekend camping trip or all-day tailgate.

Our tester had to snap points, however, as the size of the block made it difficult to fit in her freezer without extensive rearranging, nor did it fit in her small cooler. “This would have to be used in larger containers,” she says, “but I would trust both hard and soft cooler bags to keep items cold in both cold and hot temperatures.”

She used a medium-sized lined cooler to keep drinks cold for a game night and found that the igloo did a great job of keeping drinks cold, “even colder than the fridge,” she says. Additionally, “it kept drinks cold overnight and was still cold and frozen in the morning.”

Igloo’s MaxCold Ice Extra-Large Freeze Block is the bulkiest of all the ice packs our tester tried, but despite its weight (it weighs about 5 pounds), our tester would trust it to keep items cold in a larger cooler 12 or more hours, even on a hot day. In addition, despite its size, the ice block is easy to hold even when frozen due to the ribs on its surface.

What we don’t love: Had to relocate a bit to fit our tester’s freezer, doesn’t work for most small or medium-sized coolers

Although their small size is great for not taking up space in a freezer or lunch box, they don’t stay frozen as long as thicker ice packs. However, using several at a time will help prolong their longevity. These ice packs come in packs of four and are made from BPA-free plastic. If they get dirty, hand wash them with just soap and water before they’re ready to use again.

Holistic chef Niki Connor also vouches for the power of the Fit & Fresh XL in a compact space. “These packs stay cooler longer and fit easily into most [small] cooler bags when you don’t have that much space to keep your meal cool,” she says.

“After about nine hours in my daughter’s lunch box, when I removed the ice pack, the center was still frozen and was still able to keep the items cold,” she notes. While she would trust these packs to keep things like a packed lunch or snack cold for a shorter period of time, I wouldn’t use them if I need items cool for longer than 10 hours or more, or in larger containers (unless I have used multiple ice packs),” she adds.

It can feel impossible to find a reliable, slim ice pack to keep perishable food cool in a lunch box or small cooler at work or school, but Fit & Fresh’s XL Cool Coolers Freezer Slim Ice Packs are up to the task armed. Their slim profile (each is just half an inch thick) makes them easy to assemble and pack into a small space, like an average-sized lunch box, according to our tester.

“It works better for keeping chilled items cold longer (estimated max eight hours), but the items would be cool at the end of the time, not cold.” — Kelsey Graham , author and product tester

We think these are perfect for keeping drinks and food cool for an afternoon picnic or a trip to the beach. Even better, you can trim the ice sheets to better fit any size container, making them handy for weekly grocery shopping or farmers market trips.

Because they’re filled with water, these ice sheets don’t have the same long-lasting cooling properties as gel-based ice packs — but they’re advertised as being able to keep items cold for six hours or more. Our tester used these ice sheets to keep frozen treats and chilled snacks cool in the car for about three hours on a 60-degree day; When she got home, everything was still cold and intact. “I left the slabs on my counter for a few more hours just to see how long they would last, and after about eight hours out of the freezer, a lot of the ice slabs had melted, but it was still cool,” she says.

Sometimes a solid, rectangular ice pack won’t work for your needs; Luckily, the FlexiFreeze reusable ice sheets are versatile ice packs that you can mold and shape to fit almost any space. These slabs are essentially reusable ice cubes that you can freeze again and again. Our tester, who received the four-pack of 44 cubes, simply had to place the sheets in her freezer overnight and they were ready to use in the morning.

What we love: Can be shaped to fit any space, leaves can be trimmed to fit smaller containers

Unlike many others, these ice packs require assembly before use. Each pack contains a cooling gel blend that forms into a liquid gel once water is added and mixed. We were initially nervous about refilling the packs ourselves, but the instructions were easy to follow and the ice packs didn’t leak once properly sealed. Once assembled, they can be reused without having to be emptied or refilled. Our tester plans to use these in the future.

They have three layers of nylon foil for insulation, and our tester was pleased to find that they kept the items in her lunch box cool for around eight hours. I like that these packs are versatile: due to their size and long-lasting freezing (they work for different sized coolers), she thinks these ice packs might even come in handy for icing an injury in a pinch.

If you’re looking for a compact ice pack that still packs a cool punch, Cooler Shock’s reusable ice packs are what you need. These ice packs come in multiple sizes, but the lunch box size we tested, with five packs (each holding 1.5 cups), is ideal for small coolers. These slim ice packs freeze at 18 degrees Fahrenheit, and in our testing they took about 12 hours to freeze.

All in all, we recommend the Arctic Ice, with the only downside being the tested size, which makes it less versatile; That wasn’t a deal-breaker for our tester, however.

Available in four sizes, from small to extra large, the ice packs are designed with leak-proof caps and UV-stabilized ink reservoirs for long-lasting use. Our tester, who was sent the large 2.5-pound ice pack, found it a little large for her home freezer: she could have squeezed in a second one, but it would have been cramped if she wanted to put more items in it. The large ice pack also took up a lot of space in the bottom of her 12″ x 9″ cooler, with just enough room for her food and drinks.

After leaving a cooler with the ice pack in her car on an 80-degree day, our tester was pleased that it worked as advertised: her bottle of cider and assorted veggies stayed cold for four hours, and they stayed in about-about-about-about-about-superb State seven hours.

The Arctic Ice Chillin’ Brew Series cold pack is considered our top overall winner for its reliability and design. It claims to keep drinks 50 percent longer than using ice alone and takes around six to eight hours to fully freeze. It also reaches a freezing point of 28 degrees Fahrenheit, making it the ideal ice pack for keeping your drinks cold on a tailgate or a day at the beach.

What we don’t like: Can be too big to fit in small freezers or ones with lots of other items

What we love: Thin design helps with storage and use, keeps things cold for as long as advertised, easy to clean

Final Verdict

Whether it’s a quick overnight camping trip or a full day in the hot sun, the Arctic Ice Chillin’ Brew range (check it out on Amazon) will keep everything nice and cold in your cooler. The Cooler Shock Lunch Bag Ice Pack (see it on Amazon) is perfect for keeping both your lunch and snacks cool all day long.

What to look for when choosing an ice pack

size

Ice packs don’t come in one size fits all, so it’s important to have a good idea of ​​what you plan to use them for primarily – for example in a large cooler or a small lunch box. Once you know what you intend to use it for, check the dimensions of the ice pack before purchasing to ensure it will fit in your cooler or container. You should also make sure that the ice pack fits into your freezer space without too much hassle and reorganization.

Easy Recipes / Kelsey Graham

draft

Many ice packs are designed for a specific purpose, whether that’s to be thin enough to easily fit in your lunch box or to have the ability to freeze quickly over an extended period of time. Be sure to read the product description on the ice packs to ensure they are suitable for your needs. Keep in mind that some ice packs only guarantee items will stay frozen for four to six hours, while others can help keep items frozen for over 24 hours.

Size ratio of ice pack to cooler

It may seem reasonable that the size of a cooler will dictate the number of ice packs you need to keep the contents cold, but the more important relationship is that between the ice packs and the food or drink itself. In particular, regardless of the cooler size, you should need twice the amount of ice packs than the amount of food or drink. Measuring food and ice packs by weight and adding them to the cooler at a 2:1 ratio is a surefire way to keep everything perfectly chilled.

Cleaning & Storage

Most ice packs are designed for easy cleaning. If you notice food residue or other stains on the outside of the pack, simply wipe with a soft, damp tea towel or washcloth until the stains disappear. A major cleaning problem can arise when your ice pack begins to leak, especially if it’s a gel pack. In this case, you could try a DIY repair technique (there are many videos on YouTube on this subject), but the majority of ice pack manufacturers recommend discarding and replacing the leaking bag.

In terms of storage, ice packs can be kept in a cupboard at room temperature as long as you put them in the freezer to give them a good chill before needing to use them (chilling overnight is advisable). However, if you keep the packs in the freezer, you don’t have to worry about the chilling process and most packs on the market are designed for freezer storage. Place the packs in an open plastic bag or container (which will keep them sealed and prevent mess if a leak should occur) and store the bag or container in your freezer until the packs are needed.

frequently asked Questions

Why would you use an ice pack instead of regular ice?

Ice packs and regular ice work very similarly when placed in a cooler. However, many ice packs, particularly ice packs containing gel, freeze to a colder temperature than water-based ice. Plus, ice packs keep their frozen elements (whether water or gel) contained, so you don’t have to deal with melted ice and your food and drink in a cool (but not cold) bath of water. However, loose ice cubes can enclose items in a cooler more effectively than larger (and stiffer) ice packs, so cubes have an advantage when it comes to distribution.

What is the best way to pack a cool box?

The first step to packing a cooler that stays cool is to pre-chill the cooler. If you have a large fridge or freezer that fits in your cooler, put it in for a few hours before packing. If you don’t have access to a refrigerator or freezer large enough for the cooler, store the cooler in a cool, dark room before packing. The goal is to lower the temperature of the cooler itself below room temperature, which keeps the ice packs colder for longer.

Will ice packs fit on the top or bottom of my cooler?

There doesn’t seem to be a firm consensus on whether ice packs should be placed on the top or bottom of a cooler. Some recommend placing your ice pack on top of a cooler, as cold air will sink. So when you have the ice pack on your food and drinks, they stay cooler for longer. On the other hand, many outdoor and hiking websites recommend creating a layering system in your cooler, starting with an ice pack at the bottom, food and drink in the middle, and finishing with ice cubes. If you’re looking for convenience, place the ice pack on the bottom of your cooler to avoid having to move it every time you need to take out an item.

Using an ice pack for a sports injury is a common practice. Knowing when to ice the injured area and for how long is important to determine how safe and beneficial this remedy will be. This is because ice is not always the best treatment option.

Also, many people make mistakes when using this cold treatment method. We’ll go through some of these mistakes, but first, what are some reasons you should consider using ice?

Reasons to ice an injury

The most common reason ice is used for a sports injury is to reduce pain and swelling of the injured soft tissues. For decades, the traditional first aid treatment for an injury was the acronym R.I.C.E. (rest, ice, compression and elevation).

The protocol has since been upgraded to P.O.L.I.C.E. updated. (Protection, optimal load, ice, compression, elevation) for ankle sprains, tendonitis, back pain, bruises and contusions of all kinds.

While ice has been shown to greatly reduce swelling and pain immediately after an acute injury, reducing inflammation can actually impede healing in some cases, so using ice properly is important.

How long ice a breach

Ice packs should be applied to the injured area as soon as possible. They should then be applied three or more times a day for 10 to 20 minutes each for the first few days. To prevent the ice from damaging the skin, wrap a towel around it.

Although ice can be helpful, it is always beneficial to consult your doctor in the event of an injury. Follow their medical advice on treating your specific injury to ensure the best and fastest possible recovery.

Need to ice an injury?

This treatment strategy is primarily used to reduce pain and swelling that occurs with some injuries. However, icing an injury is not always the best choice, as in some cases using ice can delay healing of the injury.

Talking to your doctor can help determine if ice is appropriate and can be used to improve the healing process. Ice is generally most effective when the injury is acute or recent.

If the injury is long term (more than six weeks old) or chronic in nature, heat may work better instead.

When to use ice sprains

tribes

fractures

Tendinitis When should heat be used? Chronic or recurrent injuries

Old injuries

Stiff joints

arthritis

Common mistakes to avoid

Here are common mistakes people make when icing an injury.

icing too long

Leaving ice on an injury for too long can do more harm than good. Because ice constricts blood vessels, it can reduce blood flow to the injured area and slow the healing process.

The ideal time to cool an injury is immediately after the trauma and then for only about 10 minutes at a time (allow at least another 10 minutes between applications). It is important to allow the tissue to “warm up” again before returning ice to the injury.

Ice should not be needed after the first 24 hours unless your doctor recommends it to reduce active swelling or relieve pain.

Applying ice to bare skin

If used incorrectly, ice can cause frostbite and damage to delicate skin tissues. While cold can reduce pain and swelling, ice packs can also stop blood flow if left on the skin for too long. For this reason, always use a barrier, such as a vegetable or an ice pack.

If the injury is in an area with little fat or muscle under the skin, such as B. on the fingers, take off the compress after a maximum of 5 to 10 minutes, wait 10 minutes and put it on again.

Other strategies that might help

There are a few additional things you can do along with icing an injured area. Here are some options to consider.

Rest

Freezing alone is not a panacea and therefore, even if you follow recommendations for safely icing an injury, you must rest the injured joint immediately after the injury. It is recommended not to put weight on an injured joint for the first 24 to 48 hours.

Continuing to exercise with an injury can prolong the healing process, so check with your doctor about when you can return to exercise after an injury.

Gentle movements

While R.I.C.E. For years, the standard of care for acute injuries, research suggests that too much rest and too little exercise can impede healing. Prolonged immobilization can lead to decreased muscle strength and joint stiffness.

The new recommendation for treating injuries is P.O.L.I.C.E.: Protection

Protection Optimal loading

optimal charging I ce

ce compression

compression height

Optimal loading refers to starting gentle movements after a short period of rest after an injury and gradually increasing the level of exercise to improve range of motion and strength. Bones, tendons, ligaments, and muscles all require some level of stress to stimulate healing.

The key is to slowly increase the movement. While you may have to overcome some discomfort, if you feel pain, stop. Cooling the affected area after these exercises can help reduce pain.

elevation

Reducing swelling is an important part of the healing process and this requires elevating the injury above the heart to increase blood flow.

It’s important to raise the area while you eat. Otherwise, simply reduce the pain by numbing the area with ice, but the swelling will not go away without an increase.

compression

Along with the increase, using a compression wrap for an injury will help reduce swelling and pain in the injured joint.

If the compression is insufficient, the decrease in swelling will not last and the level of pain may not decrease as much as it would have with proper compression.

When to see your doctor

Every injury is different and sometimes the extent of the injury cannot be determined without further testing. Therefore, it is always advisable to consult your doctor to determine the best way to treat your injury based on its type and severity.

A doctor should be consulted immediately if:

The pain or swelling does not go away or gets worse with home treatment

You can no longer move the injured area

The injured area has a visible deformity

If the pain is accompanied by numbness or weakness

The pain interferes with daily activities or makes it difficult to sleep

A concussion is possible or suspected

A word from Verywell

Not all injuries are the same. While many can be treated at home with ice, some require additional treatment. The specific approach used should be tailored to the type of injury you have as well as your doctor’s recommendations.

Almost all of us will strain or irritate a muscle or ligament at some point. The resulting pain can have a major impact on your daily life.

To relieve this pain, is it better to use ice or heat?

What is inflammation?

Inflammation and pain are the body’s natural response to injury. As painful as it may be, swollen and inflamed tissue contains the healing components your body uses to repair itself after an injury.

When an area of ​​your body is inflamed, fluid (“water on a joint”) and/or irritation causes pressure in that area. It is this pressure that causes pain.

A good example is an ankle sprain. The ankle swells when it’s sprained because the body sends inflammation and increased fluid to the injured area. Inflammation can also be caused by irritation in an area of ​​body tissue, such as the B. a hangnail arise.

Depending on the type and severity of the injury, we treat inflammation in orthopedics with anti-inflammatory drugs, elevation of the injury, massage, cortisone injections, compression and rest.

Does heat increase inflammation?

Ice (cryotherapy) beats heat (thermotherapy) to treat pain and inflammation in most cases. Although heat initially feels warm and cozy, ice helps reduce pain and inflammation over the long term.

LOAD OUR ICE VS. HEAT LEADER

About applying ice

Ice constricts or constricts blood vessels. The constriction of the blood vessels prevents the body from allowing inflammation in the iced area. Heat widens or dilates blood vessels, allowing more inflammation to flow to an injured or painful area.

As a general rule of thumb, ice should be used if you have recently injured an area or had surgery or a procedure. Medical studies agree that 20 minutes of freezing is most effective. You should freeze with a cold compress or an ice pack that is the temperature of a melting ice cube.

Some people have cold allergies that cause ice to burn the skin. Place at least one thin towel between ice and skin to avoid skin burns.

Freezing for longer than 20 minutes can cause reactive vasodilation, or dilation of the vessels, as the body tries to ensure the tissues are getting the blood supply they need. Studies have also shown that it takes 30 to 40 minutes between freezing sessions to counteract this reaction. The recommended time for icing is 20 minutes and at least 30 minutes rest.

Although many articles and studies say that heat should be used for injuries and pain that last longer than six weeks, this is not necessarily the case.

With conditions like chronic tendinitis and osteoarthritis, the body believes it can heal the worn or injured area. The body continues to go through a cycle of increased inflammation despite not being able to heal these conditions on its own.

Ice cream for 20 minutes several times a day can work just as well, if not better than oral medications and injections. Controlling the inflammation often resolves or improves symptoms and reduces pain.

About applying heat

Heat matters. Heat works best in larger muscle groups. For example, heat helps relieve back muscle spasms—as long as the spasms aren’t caused by a recent fall or injury.

Moist heat or heat pads work best when used for 15 minutes at a time and at least 30 minutes.

Rules to remember:

If an injury has occurred to any part of the body within three days, ice is preferred—20 minutes on and 30 to 40 minutes off.

Pain in the back, neck, and large muscle groups like quadriceps, hamstrings, and calves respond well to heat after three days of injury.

Use ice for pain in joints like knees, elbows, and shoulders.

stay local

Do not apply ice or heat to large areas of the body if only one joint or body part is in focus. For example, a full-body ice bath should not be used to treat an ankle sprain.

The body cannot sustain vasodilation, or reduction in blood flow, over such a large area. This type of treatment will not help the injured body part, so don’t waste your time with a really cold bath.

ice & heat together

For a more advanced treatment, use ice AND heat. To get therapeutic results, you need to do it in a very specific way. The key is to cool for 20 minutes, which causes the vessels to constrict, and then heat for 15 minutes, which causes the vessels to dilate. This acts as a pumping mechanism on the inflammation, pushing it away from the injured area.

Most importantly, finish the treatment cycle on hold (unless treating a chronic back spasm). Ending up on ice constricts the vessels and prevents inflammation from re-entering the area.

Heat and ice can be applied to any injury or sore body part at any time and can provide significant pain relief.

Ice is definitely not as comfortable as heat, and ice sometimes hurts or burns for the first five to seven minutes of the 20-minute session. When used properly, it can help tremendously with most aches and pains.

I always like to say, “One icing a day keeps the orthopedist away.”

Why it’s good to discuss freezing treatments with your chiropractic doctor

Posted on May 11, 2021

staff writer

Using an ice pack after an injury is a common practice, but you can make mistakes when applying ice. Chiropractic doctors know that automatically applying an ice pack to a musculoskeletal injury may not be the best option for a speedy and full recovery.

How Ice Helps Common Injuries

The most common reason to use ice on an injury is to reduce pain and swelling of the injured soft tissues. For decades, the traditional first aid treatment for an injury used the acronym RICE – meaning rest, ice, compression, and elevation.

Today, a better-known acronym for ankle sprains, tendinitis, back pain, bruises and bruises of all kinds is POLICE, according to the article “Current Concepts in Sports Injury Rehabilitation” in the Journal of Orthopedics. POLIZEI stands for protection, optimal loading, ice, compression and height.

Here’s a guide to help you remember these principles of injury recovery:

Protection

Protection is about taking action to prevent further tissue damage. This could mean using crutches or a knee walker for daily tasks to protect an injured leg or knee. It could also mean getting the appropriate amount of rest to heal the injury.

Optimal loading

Bones, tendons, ligaments, and muscles all require some loading force to stimulate healing. Optimal loading refers to starting gentle movements or specific exercises after a short break after an injury. To improve range of motion and strength, the recommended activity level usually increases as healing progresses.

The key is to slowly increase the movement, following your chiropractic doctor’s recommendations. While you may have to overcome some discomfort, stop if you feel pain. Cooling the affected area after these exercises can also help reduce pain.

icing treatments

For some acute injuries, including sprains, applying ice treatments as soon as possible can significantly reduce swelling and pain. In other cases, reducing inflammation can impede healing. When tissue is injured, the vasculature (blood supply) to the area can be restricted, disrupting the inflammatory response. Freezing in these situations would further prevent adequate vascularization of the area.

compression

Along with the increase, a chiropractic doctor may recommend the use of a compression wrap on an injury to reduce swelling and pain in the injured joint. The tightness of the compression is important. If the compression is not strong enough, the decrease in swelling will not last and the level of pain may not be reduced as much as it could have been.

elevation

Elevating the injury site above the heart helps increase blood flow. Note: It is important to raise the area when icing. Without the elevation, simply reduce the pain by numbing the area with ice and the swelling will not go away.

Ice treatment recommended? Avoid these missteps

Sometimes, especially with sprains, it is right to apply ice as soon as possible after the injury. In those cases where freezing an injury is recommended by your chiropractic doctor or other healthcare professional, be sure to avoid these missteps.

1. Icing too long

Leaving ice on an injury for too long can do more harm than good. Because ice constricts blood vessels, it can reduce blood flow to the injured area and slow the healing process.

If freezing is indicated, the ideal time to freeze an injury is immediately after the trauma. The recommended time frame is approximately 10 minutes each with ice and waiting at least 20 minutes between ice treatments. It is important for the tissue to “warm up” again before ice is returned to the injury.

Ice should not be needed after the first 24 hours unless your doctor recommends it to reduce active swelling or relieve pain.

2. Apply ice to bare skin

If used incorrectly, ice on bare skin can cause frostbite and damage the skin’s delicate tissues. While cold can reduce pain and swelling, ice packs can also stop blood flow if left on the skin for too long. For this reason, use a barrier, e.g. a cloth towel, between your skin and a bag of frozen vegetables or a cold pack.

3. Don’t rest

Freezing alone is not a panacea. You should also rest the injured joint immediately after the injury. It is recommended not to put weight on an injured joint for the first 24 to 48 hours.

Continuing to exercise or be extremely active after an injury can prolong the healing process. Resist the temptation and check with your chiropractor or doctor when you can return to exercise or exercise.

4. Too much rest

Research suggests that too much rest and too little exercise can impede healing. A long period of immobilization can lead to decreased muscle strength and joint stiffness. It’s important, after a short rest period after an injury, to start with gentle movements to improve range of motion and strength, and gradually increase the level of exercise.

The key is to slowly increase the movement. While you may have to overcome some discomfort, if you feel pain, stop. Cooling the affected area after these exercises can also help reduce pain.

Americans ship millions of packages in the mail every day.

However, when shipping frozen food, the process gets a bit more complicated. Before you send your frozen products through the mail, you need to find a way to keep them cold, and that means using gel packs or dry ice.

So which is the better choice?

We’ve put together this guide to help you understand whether you should be using gel packs and dry ice when shipping frozen food.

Let’s start!

Gel Packs vs Dry Ice: Which Should You Use?

It all depends on what you’re shipping.

While gel packs and dry ice can both keep your packs cold, they do so at different temperatures and for different lengths of time. So before you can choose between gel packs and dry ice, you need to think about what you’re shipping.

Here are a few examples of when gel packs work better and when you should use dry ice instead.

When to use gel packs

Gel packs consist of poly bags filled with either water or polymer gel. Because of this, they freeze and thaw at about the same rate as water. Depending on the type of gel packs you receive, they may stay frozen longer.

While they can keep your frozen food cold, they thaw much faster than dry ice.

You also have to think about what happens when those gel packs thaw. Being water based, they can get wet when they start to heat up. If you don’t have the right packaging material, gel packs can wet the box, which can damage it.

For these reasons, you should use gel packs for quick deliveries and for products that don’t need to remain completely frozen during the journey. This includes foods such as:

Fresh Produce

cheese and other dairy products

Bakery products

chocolate

bread

To get the most out of your gel packs, make sure you freeze your food before packing and mailing it.

What dry ice to use

Dry ice is actually not ice at all. It consists of frozen carbon dioxide and has a temperature of -109.3 degrees Fahrenheit. This means it stays much colder than gel packs for a much longer period of time.

You also don’t have to worry about anything in your package getting wet when using dry ice. When this ice thaws, it doesn’t become liquid. Instead, it sublimates, or turns back into gas.

Dry ice keeps your food products firmly frozen until they arrive at their final destination. If you need to send something across the country or on a long journey, you should use dry ice.

It’s the ideal choice for things like:

meat

seafood

medicine

The big problem with dry ice is that it can be dangerous to handle. If you touch it without the proper protection, you could end up getting burned. And since this ice cream gives off CO2 gas, you can get serious health problems if you inhale too much.

For this reason, dry ice is considered dangerous goods when shipped. You must add the correct safety and hazard labels to your package before filling it with dry ice.

While dry ice is a helpful tool, you must be very careful when using it.

How to pack and ship frozen food

Now that you know when to use gel packs and dry ice, you need to know how to pack them properly. Without the right packaging, they can’t keep your food cold for as long as they can.

Here’s what you need to know.

Prepare your box

First, make sure you have a corrugated box. Then add a layer of insulated cardboard liners around the edges. If you don’t have cardboard liners, you can put a Styrofoam container inside the box or buy foam-insulated food shipping containers.

Line the box with gel packs or dry ice

Before you put your food in the box, line the bottom and sides of the box with your gel packs or dry ice. Fill any empty spaces or crevices with packing peanuts to keep things from sliding around.

Add your food

Place your frozen food in the middle of your package. If there is still space around your food, add more dry ice, gel packs, or packing peanuts.

It’s also a good idea to pack your groceries in an airtight bag. This keeps it cool longer.

And make sure you completely freeze your food before packing it.

Seal the box and add the correct labels

Seal your box with heavy-duty packing tape. If you used dry ice, make sure to add the required labels.

Sending frozen food by post: the dos and don’ts

Before you start shipping frozen food through the mail, you need to be sure what temperature the food needs to be during the journey. Once you know how cold it needs to be, you can decide whether gel packs or dry ice are better for your pack.

Most of the time, dry ice is the better choice when shipping frozen food. Gel packs are helpful for short trips (e.g. same-day or overnight shipping), but otherwise you should only use these packs for items that don’t need to remain completely frozen.

PCMs and gel packs are ideal for shipping temperature-sensitive products, but there is a process to prepare them.

Well conditioned gel packs can be a cost effective and valuable solution to safely ship temperature sensitive items such as pharmaceuticals, vaccines or biologics in passive containers. When using gel packs, however, they must remain at a constant temperature throughout the shipping process, regardless of external fluctuations. An increase or decrease in temperature of even 2 degrees Celsius can greatly reduce the effectiveness of a product or even spoil it altogether. So let’s discuss the best ways to condition gel packs and detail how to get the most out of them.

Gel packs (also known as coolants, refrigerants, PCMs, and ice packs) are leak-proof containers designed to maintain the recommended cold chain temperature range in a cooler or vaccine carrier. Gel packs are used in four ways:

Frozen solid gel packs are taken straight from the freezer and are typically frozen between 20 degrees Celsius and minus 25 degrees Celsius. When added to a passive tank, the temperature of the tank drops well below 0 degrees Celsius and stays there for several hours. Although they remain cold, frozen gel packs should not be used to ship temperature-sensitive products such as pharmaceuticals, vaccines, or biologics.

When added to a passive tank, the temperature of the tank drops well below 0 degrees Celsius and stays there for several hours. Although they remain cold, frozen gel packs should not be used to ship temperature-sensitive products such as pharmaceuticals, vaccines, or biologics. Conditioned gel packs are warmed or thawed at room temperature until melted and beginning to liquify. This change usually occurs at around 0 degrees Celsius. When done correctly, this process eliminates the initial risk of freezing without significantly reducing cold life.

are kept in the refrigerator and not frozen. This eliminates the risk of freezing, but lacks the cooling performance and protection that a frozen gel pack offers. Warm gel packs remain at room temperature and are typically used in extremely cold climates to prevent damage to freeze-sensitive vaccines. This article focuses solely on frozen and conditioned gel packs. After choosing a gel pack type and noting its temperature requirements, it is important to freeze it properly and then condition it to maximize potency.

A properly conditioned gel pack can prevent freezing of the product in a vaccine carrier. With this in mind, your gel pack may need to be frozen or refrigerated.

Conditioning frozen gel packs

If you require frozen units, prepare the gel pack in a large enough freezer that can cool to 0 degrees Celsius and eventually settle between minus 18 degrees Celsius and minus 20 degrees Celsius. This method eliminates the initial risk of thermal shock without reducing the time it can stay cold. It is important to use a consistent process as conditioning times can vary widely and potentially risk exposing vaccines to freezing temperatures. Appendix 3 of WHO IVB 15.03 may provide more information on the conditioning process.

You should avoid placing extremely warm gel packs in a freezer as they can change the internal temperature of the fridge and cannot be fully frozen without extra time to equalize. It’s also important to know that freezing times will vary depending on the number of gel packs you place in a freezer. Essentially, the amount and size of PCMs you load affects freeze times.

Also, avoid quick-freeze vaccines. Snap freezing (also called flash freezing), a process that occurs when samples are reduced to temperatures below minus 70 degrees Celsius, reaches the same endpoint as slower controlled freezing. However, some studies have shown that variability in freezing profiles caused by “user error” or “user technique” contributed to changes.

If you put a gel pack in a freezer, you should ensure that there is adequate air circulation around its two large, flat sides. This placement method is critical as it allows a freezer’s airflow to maximize its exposure to the gel pack, increasing the consistency of conditioning effects and reducing the risk of product damage. Also, avoid rapid freezing and prevent excessive airflow from reaching the smaller sides of a gel pack unless it’s on its large, flat side.

The contents of a gel pack increase during the freezing process as it changes from a liquid to a solid. When this modification occurs, a frozen gel pack can become distorted and its outer barriers can become brittle. Therefore, you should handle a fragile PCM with great care when transporting it from a freezer to a container. It is also important to understand that a damaged gel pack is undetectable after the freeze period until it begins to liquify.

Frozen gel packs taken directly from the freezer are not suitable for immediate use. Once the gel pack(s) are completely frozen, they should be removed from the freezer and left on their two large, flat sides at room temperature until the ice begins to melt and liquid begins to evolve. Although several factors including light, gel pack mass, humidity and air temperature can alter the time it takes for a gel pack to condition, this phase change typically takes around 30 minutes if left at room temperature.

It’s important to remember that this is the approximate time it takes to condition a gel pack and not how long it takes to freeze it, which can be 24 hours or more. In addition, a lower starting temperature can increase the effects of thermal shock. Once conditioned, you can use them immediately in a pre-qualified shipping container or air-conditioned vehicle.

The World Health Organization (WHO) reports a gel pack that is suitably conditioned once stabilized at 0 degrees Celsius. A properly conditioned gel pack has melted enough to allow ice to move within the pack. Likewise, you may notice moisture or “sweating” on the outside of the gel pack.

Conditioning gel packs for larger applications

For bulk mailing, e.g. B. in a box or on pallets, you usually receive your refrigerant as a full pallet on which several boxes are loaded. You condition your full pallets upon receipt.

As previously mentioned, mass, airflow, pallet stacking and more can affect the number of days it takes to stabilize an entire pallet of refrigerants. The greater the mass and weight, the longer you should schedule conditioning times. The refrigerants on the outside of the container stabilize their temperature more quickly than those in the middle of the pallet. This is because the colder area “touches” the outside of the pallet before it touches the inside. Depending on your freezer or refrigerator, it’s best to plan between one and two weeks to chill or freeze a fully loaded pallet of refrigerants.

Chilled gel packs

As a vaccine or pharmaceutical manufacturer, you already know a unique set of guidelines for refrigerating a gel pack rather than freezing it. First, ensure that a refrigerator’s airflow is fully operational and large enough to cool all loaded PCMs to a temperature between 5 degrees Celsius and minus 1 degree Celsius within the given time frame.

As with freezing a PCM, avoid loading excessively warm gel packs in a refrigerator as this can alter the temperature and hinder the cooling process. It’s also important to know that chilling times will vary depending on the number and size of gel packs you place in a cold room. An easy way to remember this is to consider the total mass of the gel pack instead of the number of gel packs loaded.

Finally, do not place PCMs in a refrigerated area exposed to colder temperatures than you would like, and avoid stacking unnecessarily many of them as they cool more slowly as a unit. An electronic temperature gauge or recorder should be used for protection and tracking.

Once the gel packs are properly chilled and conditioned, use them immediately after removing them from the refrigerator.

Policies and Support

The transport of pharmaceuticals along the cold chain is strictly regulated. Therefore, in order to comply with national and international standards and regulations for pharmaceutical shipping, stick to the following five basic rules:

Ship and store all products at the required temperature using properly qualified and validated shipping containers, vehicles and facilities. Monitor temperature throughout the shipping and handling process. Manually and carefully inspect all products for signs of possible damage. If the quality of the product may be compromised, destroy it or return it to the supplier for further investigation. Keep electronic records to confirm that the temperature of the product has remained constant throughout the process.

If you need help achieving your cold chain goals, contact the TempAid team.

Cool boxes are only as good as the people who pack them. If you don’t get organized properly, you’ll end up wasting all that fancy insulation you paid through the teeth for.

For tips on how to maximize this cooling capacity, I reached out to several guide friends who have taken their coolers on week-long rafting, climbing, and camping trips around the world. Here are her tips.

Cool the cooler before packing

A cold cooler keeps ice longer. If you somehow have access to a commercial freezer, let the cooler spend the night inside. For everyone else: keep it on your porch overnight or tape it in the coolest part of your house the night before your trip.

Freeze your food and drinks

If you want to have steak and chicken on the third night, pack them frozen and let them thaw over time. They contribute to the cool overall picture and are finished just in time. The same goes for your water and other non-carbonated drinks. Start with frozen bottles in the cooler and pull them out to thaw once you arrive at camp. “[Freezing bottles] is also a great way to save money,” says Lars Alvarez-Roos, a guide who owns Bio Expeditions.

Use ice blocks instead of ice cubes

Ice blocks, which you can make at home by freezing water in Tupperware, are more labor-intensive than regular cubes – you’ll need to bring a pickaxe or hammer to chip off pieces – but their extra bulk means they don’t melt nearly as quickly. “It’s easier to break off ice for your cocktails than watch cubes melt in front of your face,” says Grand Canyon guide and outdoor educator Saylor Flett.

Drain the water on long rides, but not on short ones

The guides I spoke to don’t dump the cooler water on short trips because it keeps things like beer extra cold. But the water also makes the remaining ice melt faster. So if you’re trying to preserve your blocks for the next seven days, you’ll need to empty your cooler a few times a day.

Pack in layers

Pack your blocks of ice at the bottom of the cooler, then cover the ice with a thin, firm layer like the side of a milk crate or a sheet of cardboard. This barrier prevents food from slipping between the ice and getting squishy.

Don’t trust food packaging

It’s happened to most of us: you’ve resealed the tortilla bag before putting it back in the cooler, only to find a pile of soggy porridge at breakfast. I always take my food out of the original packaging and put it in Ziploc bags or Tupperware before a trip to prevent exactly this mishap. This also reduces litter when you are at camp. Pro tip: Wrap your veggies in wet paper towels before bagging them. It will help them stay crisp longer.

Add an extra layer of insulation

Even if you own a Yeti cooler, there’s no harm in adding more insulation over your grill to ward off the blazing sun. Some people cut old sleeping pads into cooler rectangles. Reflectix works too.

Keep it locked and closed

When your cooler is completely sealed when not in use, less cold air escapes. Go into the cooler for what you need, then close it immediately so you don’t unnecessarily release cool, soothing air.

Keep your groceries organized and separated

When each type of food has its own section – meat, vegetables, spices, etc. – and you know where everything is, you can search through everything much faster.

Bring a separate beer cooler

Beer takes up a lot of space in a cooler, so give it some room to expand. Also, campers reach for beer more often than food, which can kill valuable ice cream for your chicken. Warm beer is better than salmonella.

Clean and dry your cool box after your trip

It’s easy to throw your cooler in a dark corner and take a shower when you get home. Resist. Hit the thing with soap and warm water and maybe even some bleach. You don’t want bacteria festering inside. Once the cooler is clean, allow it to dry completely. Even a little water inside can be the perfect breeding ground for all kinds of funk.

Keep it inside

Your cooler might be designed to withstand a falling tree, but it’s not designed to live in the sun, which can break down the plastic. Keep it in the garage and this thing will last forever.

The simple application of a cold pack or ice in a plastic bag and wrapped in a towel or other protective barrier (to protect skin from ice burn) is one of the most effective pain relief treatments available.

Homemade ice pack

To make an ice pack, simply place the desired amount of ice in a plastic bag (pouch) and squeeze the air out of the bag before sealing. Some like to add a little water to the ice to keep the bag from getting so clumpy. The sachet should be wrapped in a towel before applying to the painful area to protect the skin from ice burn. Other alternatives are:

A frozen towel. To make a cold pack out of a towel, place a folded, damp towel in a plastic bag and place in the freezer for ten to twenty minutes. Then take the towel out of the bag and place it on the affected area.

Disposable cold packs/ instant cold packs

Disposable cold packs have the advantage of becoming cold almost instantly due to a chemical reaction that takes place once the pack is ‘cracked’. Because they are ready to use at any time, there is no need for prior planning when it comes to placing the ice pack in the freezer. Another benefit is that the chemical reaction within the pack allows it to stay cold for longer periods while being used at room temperature. The main disadvantage of instant ice packs is that they can only be used once, making them more expensive than reusable ice packs or homemade ice packs. A variety of disposable ice packs are available at most drug and general stores.

Precautions when using ice

To avoid burning the ice pack, be sure to limit ice application to no more than twenty minutes and do not fall asleep lying on an ice pack.

As with all pain relief treatments, there are some precautions to be taken when using ice and using ice therapy.

Never apply ice directly to the skin. Instead, make sure there is a protective barrier between the ice and the skin, e.g. B. a towel.

Limit ice application to no more than fifteen or twenty minutes at a time.

Ice application should be avoided in patients with certain medical conditions, such as: B. in patients with rheumatoid arthritis, Raynaud’s syndrome, cold allergies, paralysis or areas with reduced sensitivity. Read more about Rheumatoid Arthritis of the Spine

Ice massage and ice application are generally most helpful in the first 48 hours after an injury that affects back muscles. After this initial phase, heat therapy is likely to be more beneficial to the healing process.

You can also buy ice packs that can be reused. Keep them in your freezer. Some of them are designed to wrap around an injured area like an arm or knee.

Use an ice or cold pack

Place an ice or cold pack on the injured or sore area at least three times a day while you are experiencing pain, swelling, and inflammation. Ice once every hour for 10 minutes for the first 72 hours. After that, use ice for 15 to 20 minutes three times a day: in the morning, late afternoon after work or school, and about half an hour before bed. Ice even after prolonged activity or vigorous training.

Always keep a cloth between your skin and the ice pack and press firmly against all curves of the affected area. Don’t apply ice for more than 15 to 20 minutes at a time, and don’t fall asleep with the ice on your skin.

Commercial cold packs are too heavy and bulky for use on or around the eye. Be careful around the eye to avoid chemical eye burn if a pack leaks.

Maintaining temperature control is critical when shipping sensitive goods such as chilled and frozen foods, chocolate and many pharmaceuticals, but which cooling method is right for you? Your primary options are cold packs vs. dry ice. Making the best choice for your product can be as simple as considering the key issues.

What is the desired temperature range for your shipment?

In general, dry ice is the best choice for products that you need to keep frozen, while ice packs are best for keeping the temperature of chilled goods above 32 degrees Fahrenheit (0 degrees Celsius). For example, in the food industry, the FDA requires all crude protein perishable foods to reach their destination at a maximum of 40 degrees F. Also, injectable medications generally need to stay within 2-8 degrees C.

Benefits of dry ice

Dry ice is extremely cold. It maintains a temperature of about -109.3°F (-78.5°C) as it vaporizes or sublimes and becomes carbon dioxide gas. This property makes it ideal for products that do not have a low temperature threshold. Dry ice can lower product temperature so it stays frozen longer. Dry ice is commonly used for ice cream products and sorbets, as well as frozen meat and seafood. However, never pack dry ice with freeze-sensitive products, including live seafood, flowers, fresh foods, or certain medicines. Also, it’s important to remember that all food shipped with dry ice is fully sealed to avoid dry ice changing the texture and flavor of the product.

Benefits of cold packs

When a product is perishable but must not be frozen, ice packs are the best dry ice substitute. Since cold packs are typically water based, their phase change or melting point is around 32 degrees Fahrenheit. They do not reach extremely cold temperatures like dry ice and therefore do not cause temperature damage to frost-sensitive products. Cold packs typically keep the product in the range of 2 to 8 degrees C depending on its weight and initial temperature.

Cold packs are also great for products that don’t require too much refrigeration, as well as complementing dry ice to slow down the sublimation process. As a result, cold packs can help extend the life of dry ice and cover frozen products longer during transit. Another advantage of cold packs as a dry ice substitute is that they can be added during the winter months, even at room temperature, to prevent freezing of delicate products.

Dealing with security and regulatory considerations

safety in handling. While cold packs do not require any special handling safety guidelines, dry ice must be handled with extreme caution as it is extremely cold. Skin contact with dry ice can cause severe frostbite. Skin cells can freeze and become damaged very quickly. If possible, use tongs to handle dry ice and use loose-fitting, thermally insulated gloves for manual handling. Never touch dry ice with your bare hands.

Storage and Disposal When dry ice sublimes, it releases significant amounts of CO2 gas. Therefore, be sure to store dry ice in a well-ventilated place and in a specially designed non-airtight container. When unpacking, dispose of dry ice in a well-ventilated area. Do not place in a sink or faucet where the extreme cold could damage the faucet. Many cool pack materials, on the other hand, can be fully recycled at local collection points. Contact your cold pack supplier to learn more.

Regulatory Considerations Dry ice is considered a hazardous material in the United States. Non-medical shipments containing more than 5.5 pounds of dry ice must comply with Title 49 of the Code of Federal Regulations (49 CFR) or International Air Transportation Association (IATA) rules, depending on the mode of transportation. Shipments under this weight limit require minimal package marking unless the goods to be chilled are also hazardous. There are no legal requirements for cold packs.

Decide between dry ice and cold packs

When deciding between dry ice and cold packs, the first thing to consider is the temperature requirements for your shipment and the relative merits of each approach. When handling frozen products, you can use either dry ice or ice packs. While dry ice can maintain frozen temperatures longer, cold packs are an effective dry ice alternative for frozen shipments. If you want to ship perishable goods above 32 degrees Fahrenheit, ice packs are a better option.

Instant cold packs offer a convenient cold therapy that can be used to reduce swelling and relieve discomfort from insect bites to sports injuries. These cold packs are commonly used in allergist’s offices to relieve discomfort from allergy injections. Most instant cool packs contain ammonium nitrate and water, two ingredients that, when mixed by squeezing the pack, undergo an endothermic reaction, instantly lowering the temperature of the product. When used properly, instant cold packs are safe and effective. We describe severe tissue injury caused by an instant cold pack (T-Pak Instant Cold Pack; Cardinal Health, Dublin, Ohio). Although this injury is uncommon, it is preventable.

Vaccine shipped in insulated box with gel packs

An ice pack or gel pack is a portable bag filled with water, cooling gel, or liquid that is used for cooling. They can be divided into reusable types, which function as thermal mass and need to be frozen, or instant types, which use chemicals to cool down but can only be used once. The instant type is generally limited to medical use as a cold pack to relieve pain from minor injuries, while the reusable type is used both as a cold pack and to keep food cool in portable coolers or in insulated shipping containers to keep products cool meanwhile keep transportation.[1]

Reusable packs [ edit ]

In order to be prepared for use, the pack is first placed in a freezer. Both ice and other non-toxic refrigerants (mainly water) can absorb a significant amount of heat before warming above 0°C (32°F).”

Ice packs are used in refrigerators to keep perishable foods (especially meat, dairy, eggs, etc.) outside of a fridge or freezer below the danger zone of 5–75 °C (41–167 °F) and to keep beverages comfortably cold. The amount of ice required varies with the amount of food, its initial temperature, the thermal insulation of the cool box, as well as the ambient temperature and direct sunlight. Ice that is well below freezing to begin with will last a little longer.

Water has a much higher latent heat of fusion than most substances and a melting temperature that can be conveniently and easily reached with, for example, a household freezer. Additives are often used to improve water properties. For example, substances can be added to prevent bacterial growth in the pack or to prevent the water from solidifying so that it remains a thick gel throughout use.

Gel packs are often made of non-toxic materials that remain a slow-flowing gel and therefore not easily spilled or cause contamination if the container breaks. Gel packs can be made by adding hydroxyethyl cellulose,[2] sodium polyacrylate, or vinyl-coated silica gel.

Hot-or-cold packs [ edit ]

Hot-or-cold packs are cold packs that are designed for use at high temperatures. They can be used as regular reusable ice packs by storing them in a freezer, but they can also be heated in water or a microwave oven to reach the desired temperature. The first heat and cold pack was introduced in 1948 under the name Hot-R-Cold-Pak and could be chilled in the refrigerator or heated in hot water.[3] The first reusable hot-cold pack that could be heated in boiling water or in the microwave was first patented in 1973[4].

Instant ice packs [ edit ]

An instant cold pack is a disposable device consisting of two sachets; one with water in a bag of ammonium nitrate, calcium ammonium nitrate, or urea. When the inner water pouch is ruptured by squeezing the package, it dissolves the solid in an endothermic process. This process absorbs heat from the environment, quickly lowering the pack’s temperature.[5]

Instant cold packs are a convenient direct replacement for crushed ice used as first aid for sports injuries and can be taken as first aid to remote or wild areas where ice is unavailable or not appropriate for the situation.

Security concerns[edit]

Gel packs were made with diethylene glycol and ethylene glycol. Both can cause disease when ingested in large amounts,[6] making them unsuitable for food use. The US Consumer Product Safety Commission has recalled such packaging.[6]
