Dry Ice Packs for Shipping - Long Lasting ice Packs - 24+ Hour Freeze Power - BPA Free - 48 Pack Bulk 12 lb – Hielo Seco - Reusable Gel Bricks for Food

These freezer packs work great for general usage, and as long as you follow the basic instructions, you shouldn't have an issue (barring manufacturing defects). The sheet includes 12 individual "cells" that are perforated for easy separation, allowing you to customize the layout/coverage as needed, and do actually last a surprising period of time. Note that when you first hydrate these, if you place them under running water, watch them closely, as you can hydrate them to the point the cover is stretched tightly, making these more round than flat, and harder to flat pack in your container. I've only used a couple of them a few times, but so far have not had leakage issues, but they are colder than some of the other gel packs I've used (I froze these as per instructions for 24 hrs prior to using them) and did have more condensation on the non-mesh side than with other gel packs. Overall, these have been a great solution for small portable applications (I have a leather dog treat pouch I made for "high value" reward treats, and some snacks for me, I wanted to keep cold/cool), and even on longer walks in 80F+ degree temperatures under direct sunlight for 1+hrs, the contents stayed cold to the touch and fresh, something I've been having trouble achieving with non-gel ice packs.

These ice packs are great; they are easy to use, a perfect fit for shipping care packages, stay cold for a long time, are durable, and don't leak. Perfect for lunch bags, coolers, or injuries, great quality, and exactly what I needed. Highly recommend.

These are mini ice packs in a sheet. There is a porous membrane material side and a plastic side that make up a pouch filled with insta-snow powder. Once activated with water, the snow fluffs up into a gel that once frozen will retain the cold. My daughter ran it under the tap for 45 seconds and squished the inside around to throughly mix the powder and get a good reconstitution. We then blot dry and put it into the freezer overnight. I like the functionality of being able to break them apart into little pieces to put in various container sizes. In this case, we used it for a picnic so I kept the full sheet. During the hike, kids got hot so they took pieces of this and each one had a nice cooling ice pack, and because of the soft membrane side, they were able to put it on their skin with feeling cold burns. At the end of the day, this is put back into the freezer for next time. It seemed study as the pack didn’t burst open or leak, even with the kid’s tossing them around and playing with them. The ice in the picnic basket stayed frozen for a few hours, and then was able to still maintain cooled temperatures for up to 6hours in total (as a whole unit), the pieces the kids took apart to play with only lasted 1.5hours before it was no longer cold. Good value for the number of sheets you get. Worth it for everyday use for lunch bags, boo boo packs, quick cool off, fevers, etc.

Perfect for the need. Easy to use and kept good frozen. Mail an item from SC to Co. took 3 days and food was still cold.

I also happy with this product. I use it to fill the cooler with drinks for the people who deliver items to my home. It worked out well because the cooler stays in the heat for hours but the ice continues to keep the drinks cold. Thank you 😊

These arrive as flat as a credit card and absorb water when immersed, then you freeze them! Uses the same tech as the gel guns for kids! Great way to have some freezable item ready to go without taking up storage space in your freezer!

The details say that they will be flat, however when I soaked them, they swelled up and was not flat any longer. We used them anyways outside to keep metal bowls cold to display our dips at vendor events, they did not stay cold long enough, which was only 4 hours. Ok, but not for event usage.

Work well a bit smaller than I expected

also stay cool for extended periods of time.

Easy to use and reuse, it’s so cool that it comes in flat sheets and you just allow the water to run into them and fill to desired size. Freeze and they are ready. We left ours out at 22oC temperature to see what would happen and they lasted 7 hours, without being in any cooler and never lost a drop of moisture. Definitely will buy more in the future! Great product.

molded after a year of use. Maybe i let it sit defrosted for too long but it wasn't fun to discover. I would keep majority just in storage and use 4 at a time. I like how its compact to store and you can shape it into whatever you want in the freezer.

I’ve ordered product similar to this and I was looking forward to them staying in large pieces however once soaked in water they all fell apart into individual pieces not very useful except for lunches
