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

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.

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.

The product was easy to use and easy to separate each ice pack. The packs stayed cold in shipping. Very satisfied.

They did not work for what we intended them for, but most likely with a Styrofoam box they would be perfect for shipping. I enjoy that these are just as easy as "just add water and freeze" ice pack. I never have extra room in my freezer for anything but these were perfectly small and compact. They are great for lunches, afternoons out, and only for the day uses out and about. They are perfect to take with in your lunch box because the the food is gone you can throw these away instead of trying to remember to take it back inside and refreeze. They ended up having great uses even if it wasnt for the intended purchase. There were a great amount in the package for the price. The quality is great for short term use, they didnt leak until well after 12 hours when they were completely unfrozen.

A couple months ago I was looking for something like dry ice packs to keep bottles cold when we were out and about in the heat. I stumbled across Luna Ice packs and bought some (36 count). Those things stayed cold for a LONG time in our small bottle bag. When I knew we were going to be traveling 14+ hours to Texas for Thanksgiving I knew I would need to keep stuff freezer cold. I had 120+ ounces of frozen breastmilk to bring for baby girl, 10+ dozen macarons to bring for the anniversary party the day after Thanksgiving and a sugar cream pie for Thanksgiving. I got an Igloo cooler for $30 brand new and I bought more Luna Ice packs (48 more). We did add some dry ice to the bottom of the cooler but it was expensive so we didn't add much. That cooler stayed COLD from Wednesday morning until Friday evening! Many of the Luna Ice packs were still completely frozen on Friday. I even took a ton of the stuff out on Friday and it was still cool on Saturday when I repacked it. Oh and the dry ice was gone by Thursday so it was all Luna Ice keeping stuff cold. I do know that the actual cooler played a roll in everything staying frozen for over 48 hours but I also know I have used Luna Ice in not as good coolers and it has always been at least partially frozen when I am done needing them. I had written to Luna Ice to tell them how great they were and to let them know the code that came in the packs I recently bought didn't work anymore. They asked for my order number and told me they would send me a gift and this is what came in the mail! Now I have over 200 of these amazing little ice packs! They will definitely come in handy when we go camping next summer!
