Techni-Ice dry  Cold / Heat Packs

At last, a new technology that is a vast improvement on traditional ice packs / gel packs and which can also be heated.
Techni Ice reusable packs are revolutionary because they can be used hot, cold or frozen. They are ideal for keeping food hot or cold, medication cool or warm and are especially useful for hot or cold compresses on any part of the body.
Techni Ice reusable 4-ply packs comprise:
2 non-woven textile layers, which encapsulate a special cross-linked polyacrylate polyalcohol co-polymer refrigerant combined with a post treated trade secret formula.
2 heavy-duty plastic layers, containing one-way micro-perforation technology.
These 4 layers are bonded together, thus ensuring that each sheet withstands the harshest of operational climates, with performance that can only be described as revolutionary.
Thanks to this advanced and incredible technology, the sheets can be frozen right down to minus 190C (that’s more than twice as cold as dry ice!). Techni Ice reusable packs are often frozen in blast freezers to minus 80C when used in dry ice applications.
A Techni Ice reusable dry pack starts as a flat sheet, which absorbs water through a special perforation technology in its surface. The process takes approximately half an hour, after which it is ready to be placed in the freezer, fridge or microwave – see separate instructions.
Each sheet (39.5cm x 28cm) is divided into 24 (Standard Type) or 48 (Elliptical Type) individually sealed cells, which means the sheet is flexible when either frozen or heated. It can also be cut to any convenient size. The same sheet can be used for freezing on one occasion and then heating for another application.
