The claimed world’s first reuseable ice wrap bandage is using DuPont Surlyn packaging resin to seal in the cold.

Liquid Ice Wrap from US company Americool, is a first aid treatment soaked in a proprietary menthol and alcohol coolant that stays cool for up to two hours after removal from the pack.

A critical aspect to the product’s functionality is the foil pouch with a layered interliner that is alcohol sensitive yet compatible with the bandage. Americool tested packaging materials over three years and concluded DuPont Surlyn offered unmatched integrity and durability.
