What is a Reusable Ice Pack?
It speaks for itself, and the clue is in the name. It’s an ice pack you can use time and again. They can be frozen before each use and, as long as the outer packaging remains intact, can be used again and again, and will last for quite some time.
They contain water and generally some other additives to increase viscosity, such as a refrigerant gel. The contents are often blue, so you can see them clearly if you have any leakage. If you find blue sandwiches in your cooler, throw them in the trash!
Do you remember the soft blue ice packs your Mom used to put in your Spider-Man or Barbie lunchbox for school? I used to like squishing them — turns out this was not a good idea. The gel was petroleum based and could cause illness if ingested. The Consumer Product Safety Commission recalled most of these packs eventually.
Many companies now make ice packs from environmentally friendly, non-toxic, chemical-free products. They also focus on phase change materials, which are non-toxic and biodegradable.
Now for a bit of science.
A phase change material (PCM) is one that changes from a solid to liquid state when it absorbs heat. Once it changes its state or phase, it then holds onto that heat and stores it as energy. Eventually, it fully melts and releases the heat at a normal level again.
The advantage of a PCM is it really does lock down the heat. The whole ice pack has to reach its melting point before the phase change begins. It then holds the latent heat until it’s fully melted — this means less heat in your cooler.
Other products replacing the more toxic traditional style ones, are foil packs. They contain a refrigerant gel within layers of nylon and foil.
Initially designed for keeping blood at a constant temperature during transportation, this technology has now hit the ice pack for coolers market. Similar to a phase change material, they keep the heat they absorb, and help your coolers stay cold.
Reusable Ice Packs Vs Regular Ice: Which is Better?
Ice packs have a couple of advantages over regular ice. They will stay frozen for longer, and they won’t leave your cooler swimming in water. The last thing you want on a sunny day out is hot juice and saturated snacks at the bottom of the cooler.
Regular ice is easier to pack around canned or bottled drinks and might take up less volume than a reusable ice pack. However, it does melt quicker, making it not so good for food storage.
Using a combination of reusable packs and regular ice is always an option. This gives you the best of both worlds. The cool packs will help your ice stay frozen longer, keeping your cooler’s internal temperature lower; sometimes for up to twice as long. Plus, if you take cups, you can use the ice in your drinks.
Smaller reusable ice packs are great for adding to lunch bags, bento boxes and other small insulating bags. They’re also ideal for use when grocery shopping, keeping frozen goods from melting on the trip home.
Another thing to consider is cost. Buying regular ice and having to keep replacing it can work out expensive, especially if it’s a regular purchase. You’re basically paying for something which just melts and is then thrown away.
Reusable cool packs can last for several years, so while the initial outlay is going to be more, they will quickly pay for themselves over time. Just rinse them and pop them back in the freezer after use, ready for next time.
Which to use all comes down to a matter of personal choice in the end. Regular ice might be better for beverages, from a packing point of view. Reusable ice packs can be better for perishable goods: they don’t leave the bottom of your cooler looking like a filled bathtub.
Either way, reusable ice packs will not defrost as quickly as regular ice. It’s also worth noting there are some that can fit into gaps or are pliant enough to be molded around the items in your cooler.
What to Look for in the Best Cooler Ice Packs
Below are some considerations you need to think about when choosing an ice pack for your cooler.
How Long Will it Last?
Take your planned activities into account when choosing your ice packs. Do you want them for a weekend of camping, fishing or hunting? Will they just be used for a day at the beach or a tailgate party? Do you just need something to keep the kids’ lunch cool?
Different products will last for varying lengths of time. Make sure you choose one that will stay frozen for as long as you need.
Some will last from 4 to 12 hours, and others will stay cold for up to 48 hours or more, in ideal circumstances.
You need to make sure you have enough room left in your cooler for all the food and drink you want to keep cold.
Think about how much space your ice packs are going to take up. Look at the height, width, and depth. Remember, most won’t fill uneven gaps in the same way regular ice will.
Fortunately, there are flexible options available for smaller coolers or odd spaces, and slim ice packs for lunch boxes.
Be aware that coolers specifically made to hold a certain number of cans fitting perfectly inside, will lose some volume if you add ice packs. Take this into account in your planning.
Depending on the size and freezing agent in your ice pack, the weight can vary greatly. If you might need to carry your cooler for long distances, from the car to the riverbank on a fishing trip for example, this is definitely something to consider.
Of course, if you’re buying ice packs for use inside wheeled coolers, then weight is less of a consideration.
The other consideration here is how much regular ice they replace. A pack that weighs just a few pounds will be more efficient at cooling as the same weight of regular ice. It will also take up much less space, last longer and leave no mess.
Most ice packs have a flexible outer casing, while others have a hard shell. If you know your cooler is likely to take a bashing when you’re out fishing or hunting, you’ll want your ice pack to be durable and strong. This will help prevent breakages and leakages.
Softer casings, particularly for gel-filled packs, will be better for packing around irregular shaped goods or filling smaller gaps in your cooler.
Just like anything else in life, a higher cost usually means better quality. A cheap ice pack might seem a good option when you buy it but may not last very long.
My advice is to buy the best cooler ice packs you can afford. A good quality ice pack will likely last much longer and actually cost you less in the long run. Even the most expensive ones won’t break the bank but are less likely to need replacing.
Materials and Durability
Most hard cases are plastic and will withstand knocks and impacts.
Make sure to look for cooler packs that are BPA free. BPA is an abbreviation of Bisphenol A, a chemical that is sometimes used to make plastics. It has been shown to have adverse effects on health, such as fertility and cardiovascular issues.
Hard casings are likely to last longer than some softer foil and nylon options, although they’re not as flexible.
We have mentioned that the use of petroleum-based products for ice packs is now not general practice. However, there are still some out there, so check the labels carefully before purchasing.
If it’s labeled as non-toxic, it indicates it is safe, free from poisons, and won’t cause health issues when used as intended. If you are unsure, check out the product contents and the manufacturer.
Something labeled as non-hazardous means it should not contain chemicals, solids, liquids or gases which are a danger to you or the environment. This might also be labeled as chemical free.
Products which are sustainable or environmentally friendly will generally have little or no impact on our ecosystems or environments.
Summing it up
There is little doubt that a good ice pack is a great addition to your arsenal for keeping food and beverages cold. It’s an essential bit of kit for summer weekends away, camping, tailgating, fishing, or everyday lunch boxes.
Whether you choose to use them alone or in conjunction with regular ice, the best reusable ice packs will save you money in the long run. They will also cut down on runs for ice to keep that cooler topped up. More time to chill and enjoy yourself — and no warm drinks.
