Techni Ice Heavy Duty 4 Ply Reusable Ice & Heat Packs (20 sheets)

Techni Ice reusable dry ice packs/gel packs start as a flat sheet and absorbs water through a special perforation technology in the surface of the product.This is achieved by scrunching the sheets between your hands whilst immersed in warm water for a few minutes until the air bubbles have escaped.The hydration process will now begin and the cells will swell ready for the products to be used both cold or hot. The water enters through the surface and activates the polymer, which then swells the sheet into 24 individually sealed cells Which enables the product to be flexible when frozen and cut to size. Techni Ice reusable dry ice packs/gel packs can be used hot, cold or frozen can not only keep your food and drinks icy cold for days on end in the cooler but is also very effective at reducing battery consumption when placed in 12 volt fridge/freezers due to its eutectic qualities, which minimize thermostat activity.
