I couldn’t help buying these to match his super cute lunch bag and bentgo box. These are great for the price! They fit perfectly under the bentgo box and on top of you wanted too. They seem well made and don’t appear like they’ll ever leak which is awesome!

Healthy Packers’ Ice Pack will undoubtedly keep your insulated lunch pack freezer-cold for a longer period of time! It keeps your meals fresh and your body fit for several hours by staying as cold as ice. You will get a set of 5 thin multipurpose solid gel ice packs, each measuring 4.8 x 4.8 x 0.6 inches. It’s ideal for back-to-school chillers, as well as daily usage in lunch packs, bento boxes, and coolers. These little babies surely pack a powerful punch!

Perfect fit for kid lunch boxes so it keeps food cool enough until lunch but doesn’t weigh their already heavy backpacks down.

A larger ice pack could be preferable for older children with larger lunch boxes. It’s also far thicker than other ice packs, so it’ll keep colder for a longer period of time. This reusable ice pack is flat and rectangular, so it fits perfectly into the bottom of a lunch box, but its greater size makes it significantly heavier than other ice packs. A big central cutout offers a safe grip, and the plastic case houses a nontoxic filling. Plus, with its opaque blue color blocking, this one looks a bit sleeker than others.

I like these because they lay flat in the bottom of my lunch bag and don’t take up too much space. Keeps lunch bag cool/cold all day.

Consider this value pack if you’re preparing multiple lunch boxes for school or childcare. The kit contains ten small and lightweight ice packs that are perfect for lunches. According to the manufacturer, each square remains frozen for more than three hours and chilly for more than eight hours. These ice packs are squared with jigsaw edges that link to produce longer ice packs or even cubes for bigger containers, such as coolers.

Cant beat the price for 10 ice packs! They stay cold in my lunch box for 8 plus hours!

For small coolers or lunch boxes, use one or two Fit & Fresh Cool Coolers Slim Ice Packs, or stack a few into a bigger cooler to keep temps low and food fresh throughout your summer party on the lawn. The small, space-saving packs are simple to clean and can keep you cool for up to 12 hours. They’re ideal for cramming into small places or stacking together for even more cooling power. Freeze the ice packs the night before usage for optimal cooling power.

These are nice and thin for lunch boxes. They stay frozen for awhile as i tested one out in my own lunch box leaving out in the open on my desk at work and it was still 1/4 frozen by noon (from being out of the freezer at 630am).

The Coldest Circle Ice Packs are particularly created and designed for athletes and top performers on the move to recover tiny portions of their bodies quicker.

The six-pack of the Coldest Circle Ice Packs was designed with you in mind and will be there for you whenever you need it.

These ice packs for lunch boxes come in a bundle of five slim, rectangular packs in a variety of colors and are an overall wonderful option for their design and pricing. These chillers are meant to fit neatly inside lunch boxes or coolers, and according to a handful of reviewers, they keep cold for four to seven hours. These reusable ice packs are comprised of safe, BPA-free materials. Each has indentations and center cutouts for a secure grip.

Slim and perfect to keep lunch cool. These do not add bulk to lunch box. I use two to keep salad and can of water cold for lunch, but one would probably be sufficient. Often still functioning at end of the day if kept insulated. Recommend.

If you want a lunch bag that works overtime, this option can be placed in your freezer so that the walls are totally frozen when you’re ready to pack your food, keeping it refrigerated for roughly three to four hours, according to reviews. The foldable bag has a zip-top closure, a broad base to fit various food containers, and a nontoxic gel and gel lining. It has a 4.6-star rating and over 7,000 reviews, making it a popular choice.

Probably not leak proof, but no issues. Good lunch box. This is our second of this brand, the first is surviving child use and wife wanted one to use for baby. Not a huge bag but convenient.

In terms of flexibility, the FlexiFreeze Ice Sheet is an excellent option for an ice pack. It has multiple chemical-free ice sheets that are water-based. This way, you can cut the sheets to the size you want. Another astonishing feature of this ice sheet is that it is very flexible even when frozen. You can mold and move them any way you like. FlexiFreeze Ice Sheet is one of the best ice packs for lunches, coolers, and other containers.

These are the handiest, most versatile, things! Cut to size, freeze, and you have a customized fit for your cooling needs. I've used the same sheet more than a hundred time for my husband's lunch box, and it's still perfect. Love them!

Cooler Shock 3x screws cap fill and seal cooler freezer packs are extra-large packs ideal for carrying a large cooler for a day in the woods. It’s reusable, slushy, and cold—colder than ice at 18 degrees Fahrenheit. These extra-large cooler ice packs are equivalent to around 20 pounds of ice. So there will be no filthy water in your cooler! Simply fill them with water via the screw top, set them in your freezer for approximately a day, and they’ll keep your drinks cool for up to 48 hours!

I bought these for my husband to use in his lunch box that sometimes sits out in his truck on very hot days. I love the slim design and the fact that they hold the cold for quite a long time. Highly recommended.
