When you dream of a day of fun on the beach, sun, and sand, coolers filled with ice probably feature in the daydream. While ice is the traditional way to chill your food and drinks in your cooler, ice has some downsides. Unless you have a high-capacity ice maker, you typically must buy bags of ice, which means making a trip to the store and paying for something that will soon turn into dirty water at the bottom of your cooler.

Gel ice packs present a better option. The best ice packs for coolers can provide as much, if not more, cooling power than ice, with some food staying cool for as long as two days when paired with the right cooler. And they’re reusable, saving money and the hassle of having to purchase ice. Moreover, soggy sandwiches and cooler cleanup become a thing of the past.

Read on to learn more about the factors to consider when shopping for an ice pack and to find a list of the best ice packs on the market for keeping your cooler cool.

What to Consider When Buying 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.

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.

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 coolers, while smaller ice packs are suitable for kids’ lunchboxes. 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.

Versatility

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 boxes to large coolers.

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.

FAQ About Your New Ice Packs

If you still have burning questions about ice packs, 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.
