What to Consider When Choosing the Best Ice Packs for Coolers
While all cooler packs use a frozen gel or liquid to keep coolers cool, they have notable differences in size, freezing point, and longevity making them a must-have summer hack for barbecues, patios, and cookouts.
Type
Ice packs come as either hard-sided packs or soft packs. Soft packs allow users to conform the ice pack around the items, which is ideal for soft lunch bags and coolers, while hard-sided packs provide a more rigid block that can fit neatly into a rigid square cooler.
Freezer packs are manufactured in various shapes to meet different needs. Some ice packs can be stacked or connected to create larger ice packs or different shapes, allowing them to be used in a range of applications, from lunch box coolers to large coolers.
Size
Consider the size of the ice pack: Bigger doesn't always mean better. While a larger ice pack may provide more cooling power, it will take up more precious real estate in the freezer and reduce the available space in the cooler for food and drinks.
Also consider the type of container. Larger ice packs work well in large units, while smaller ice packs are suitable for small coolers. Ice packs range in size from about 5 inches wide by 5 inches long up to 10 inches wide by 13 inches long. Ice packs can weigh less than a pound or up to 5 pounds.
Freezing Point
Freezing point determines just how long the ice pack will stay cold, and, in turn, the temperature in the cooler. Most ice packs contain a gel that consists of one of three nontoxic substances: hydroxyethylcellulose, sodium polyacrylate, or silica gel. These gels are contained in a bag or hard shell made of vinyl or plastic. The gels have a much lower freezing point than water. A gel with a freezing point of 10 degrees Fahrenheit stays cold longer than water, which has a freezing point of 32 degrees Fahrenheit.
When choosing a gel freezer pack, consider some of their characteristics. Gel-based ice packs often trap air bubbles because gel is more viscous than water. Trapped air bubbles can cause hard shell freezer packs to balloon out, ruining their flat shape. Higher-quality cooler packs feature tough plastic shells that resist ballooning.
Longevity
When determining the length of time that an ice pack will stay cold, size is the best indicator. An ice pack that weighs 4 pounds will stay cold longer than one that weighs 2 pounds. A 5-pound ice pack used inside a quality cooler can stay cold for up to two days. Since they're thicker, hard-sided blocks also stay cold significantly longer than soft ice packs.
Our Top Picks
The following ice packs are made by some of the most innovative companies in the business. They offer superior longevity, are made from durable materials, and meet a variety of different cooling applications. Read on to find some of the best ice packs for coolers.

How We Chose the Best Ice Packs for Coolers
The right ice pack can help to keep food cool in your lunch bag or drinks cold in your cooler. Selections for the best ice packs depended upon size, weight, freezing point, construction type, and materials used.
Large and small ice packs for coolers are represented on this list with either hard or soft constructions for your intended use. Each pick is also made with specific dimensions, most coming in thin, rectangular shapes to fit flush on the bottom, sides, or top of a cooler.

Freezing point is also a concern with ice packs, but each of these picks freezes quickly at 0 to 32 degrees Fahrenheit. Though these picks are filled with gel, water, or both, each is tear and impact-proof to avoid leaks and toxins from entering your cooler. Finally, select picks are also made BPA-free for peace of mind.
FAQs
If you still have burning questions about ice packs for coolers, read on to find out how ice packs compare to ice, how long they last, and how to dispose of the worn-out packs.
Q: Do cooler ice packs work as well as regular ice?
No evidence suggests that ice packs stay cold longer than ice; however, many ice packs feature lower freezing points, which means they can maintain a colder temperature than ice during the thawing period. Keep in mind that ice, which is either crushed or in numerous cubes, can better surround items, keeping food and drinks more evenly chilled than rigid ice packs that cannot be dispersed throughout the cooler as easily.
Q: How long do ice packs last?
Chilling time depends on the size of the ice pack and the quality of the cooler. Generally, larger and heavier ice packs last longer than smaller ones. Some of the best large ice packs can last up to two full days in a quality cooler.
Q: How do you discard ice packs?
When consumers consider the environmental hazards of discarding ice packs, they're usually concerned about the bright blue gel inside the packs. While the gel looks as if it could be hazardous to your health, most gel in ice packs is nontoxic and biodegradable. The real problem is the plastic coating that contains the gel, which is not biodegradable. To be responsible, cut open the gel pack, empty the gel into the garbage, and then dispose of the plastic part by taking it to a plastic bag recycling center.
