I bought this tape specifically for sealing industrial ice packs - the kind you get in the mail with refrigerated medication - which expire. I didn't want to keep asking the community for new ones when I didn't have to. I sealed the spots on two packages and sealed the whole package with electrical tape (I didn't find a hole). I use ice for migraines, so I basically freeze them completely, then wrap them in a towel and rest my head on them until they thaw, then put them back in the freezer. It's been a few months now and the tape has withstood all these conditions perfectly, both on sealed packs and on strips. I've also used it to patch a broken handle on a plastic laundry basket and it sticks and holds great despite the uneven surface and not so dexterous application.
