Dry Ice Packs for Shipping - Long Lasting ice Packs - 24+ Hour Freeze Power - BPA Free - 12 Pack Bulk 3 lb – Hielo Seco - Reusable Gel Bricks for Food

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.

Wanted to share my wedding cake with my family in Ecuador and I’m in New Jersey. Packed these in a lunch box with aluminum plus the cake was frozen solid as well. It traveled for 15+ hours and the packs worked perfectly. Also LOVED the picture of Luna the Husky that you get in a thank you card. Way took cute!!!

I cater for charter flights and yachts and never knew I could just buy some dry ice that is shelf, stable and activated by soaking it in the sink for three minutes and then putting it in the freezer. I could not believe it. It lasted for 12 hours just like it said it would on the package. I know this sounds silly, but I catered for a charter flight and the gentleman wanted a milkshake. Often times the delivery may have to sit there for a couple hours before the flight takes off, so I used the dry ice packs which were extremely affordable as disposable ice packs and everything went extremely well. I will use them from now on awesome product.

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.

They were easy to “inflate” and freeze but as soon as I went to use them they all came apart into individual pieces, no longer a sheet as I had wanted. They did stay cold and was helpful in our cooler to keep things cold, but they were unfrozen by end of the day in an insulated cooler. On subsequent days we used the small individual pieces shoved down in between items while we used other vendor ice sheets.

Worked great! Sent frozen food to a friend who had surgery. With these ice packs, and an insulated box, the food was still frozen when it arrived 53 hours later.

Small packets of dry ice are great for any container you are using for long or short trips. Easy to use, last for long time. Don't be afraid to try this product.

Worked well for one time use. Good price point for that if its what you're looking for. Lasted the delivery trip. Liked it overall. Would buy again.
