Summer is a great time for outdoor activities such as picnics, BBQ parties, or camping by the beach. It’s great to drink a cool bottle of water during outings in hot weather. All of that gives a natural summer feel. However, it will be challenging to keep drinks cold if you do not know that ice packs for coolers are what you need. Investing in ice packs for coolers brings long-term value and excellent benefits. For good cooling efficiency and without spending too much, you should know the basics and how to choose the best ice packs for coolers. This article will give you all.
What are ice packs?
An ice pack is a portable bag of cooling liquids or gels manufactured to cool food and drinking water. Based on the characteristics and usage time, people divide ice packs for coolers into two main types: reusable and instant cooling. Due to the different properties, the internal components of these two types of cooling ice bags are also completely different. Understanding each type will help you choose the suitable ice pack for you.
Reusable ice packs
Tthis type of ice pack acts similar to an ice block and freezes when needed for cooling purposes. When you need to use it, you must put it in the freezer until frozen. The refrigerant inside this ice pack is non-toxic, with the main ingredient being water. It can be at a temperature as low as 0 degrees Celsius. Depending on the needs of cooling food, users can choose the appropriate number of reusable ice packs. In addition, you should also consider the ambient temperature when using this type of cooler bag.

Instant cooling type
This ice pack can only be used once. It consists of two bags: one for water and the other for solutions such as ammonium nitrate, urea, and calcium ammonium nitrate. When the two bags are crushed and dissolved, the inside of the ice pack forms an endothermic process that causes it to cool quickly. Usually, this type of bag is only used in cases of needing first aid, injury, temperature rise due to illness, etc. The cooling time of this ice pack is short, so it is difficult to cool foods and drink water.
As such, ice packs for coolers are usually reusable ice packs. Therefore, you should pay attention to buying the suitable types if you do not have the purpose of preparing wounds and healing.

Safe for health
Ice packs’ primary purpose for coolers is to cool drinking water and food. People often use this ice pack to support coolers to increase capacity and prolong cooling time. You just need to put these ice packs in coolers to enjoy their effects.
Besides, ice packs for coolers do not contaminate food with harmful substances, so you can rest assured about their safety.

No messy water
The benefit of using regular ice in your cooler is that the ice cubes are smaller and can be placed in tighter positions. This will help cover more of the area in between the food and drink but you must struggle to clean up with messy water.
When your ice packs finally melt, they won’t spread all over and flood everything as is the case with regular ice. The ice packs are reusable, and the substance stays inside as it melts, so you don’t have to worry about your entire food being submerged in water.
In addition, some cooler bags are not completely leakproof, using regular ice can lead to water melting and leaking through your bag, into your car or even onto your clothes. With ice packs, you just need to store them in the freezer after your travels, they will be ready to use again next time.

For longer trips, it is recommended that you fill the cooler half full or 2/3 full with ice or an ice pack. But in a small cooler, this is often not possible because there is not enough room for food and drinks. You should pack as many ice packs as you can fit in your cooler. The more you pack, the longer things will stay cold.
Ice packs come in a variety of sizes and forms, from small enough to fit in a lunch box to large enough to serve a group with drinks and snacks.
How long do ice packs keep a cooler cold?
Typically, a 5-pound ice pack can keep a quality cooler stay cold for up to two or three days. The gel ice packs can keep the cooler cold up to 5 or 6 days if placed in a well-insulated cooler and pack properly. Usually, the ice pack will stay cold and will keep the cooler or contents inside cold for more than 24 hours.
Heavy and large ice packs will keep cold longer than small and light ice packs. Because they are thicker, hard-sided blocks, they stay cold significantly longer than soft-sided blocks.

Should ice packs go on top or bottom of a cooler?
Ice packs are best placed at the bottom of your cooler as they will last longer and keep things cold longer. Let’s take a look at the locations to put your ice pack and the pros and cons of each.
On the bottom
Placing an ice pack on the bottom of the cooler will ensure that it lasts longer and melts more slowly. This is ideal for longer trips where you need to keep your food from spoiling for a long time. Food and drinks on the ice will insulate and protect it from the outside air every time you open the cooler. Placing them at the bottom will prolong the life of the ice pack.
Also, placing the ice packs on the bottom of the cooler is very convenient because you will not have to move them every time you need to take out foods or drinks.
The disadvantage of this method is that the items at the top won’t be as cold as the items on the bottom. However, with the right arrangement, you can make this work. For example: place perishable items such as dairy products directly on or under the ice pack. Then place other drinks. Things like bread and fruit on the very top.

Putting ice packs on top is a good solution. As a rule, cold air will flow from the top of the ice bag to the bottom allowing cold air to seep into all your items, keeping everything cold. But because they’re on top, these ice packs are exposed to more warm air when the cooler is open, and so they’ll melt faster than if you left them at the bottom.
This method is good for short trips but not ideal for longer rides when you need to maximize your ice holding capacity.
Another way to arrange ice packs is between products. The cooler doesn’t have the thick insulation as a regular fridge and your ice packs won’t keep everything in your cooler equally cold. Placing ice packs between your products will ensure that each item is equally cooled as they are in direct contact with the ice packs.
