Techni-ICE, Better Than Ice or Gel Packs! Reusable, Dry Ice Replacement - Single Sheet

Techni Ice reusable ice packs are here to make your life easier! Techni Ice HDR consists of a 4 layer construction - the two outer layers are a heavy duty plastic while the two inner layers are made to protect and hold the main ingredients. Techni Ice is made of cross-linked polyacrylate polyalcohol co-polymer refrigerant that is combined with a proprietary secret formula to give you the best results! It is also non-toxic! The outside layers are puncture resistant to keep your ice pack safe and sturdy. When your Techni Ice arrives it will be in thin sheets that require hydrating before freezing or heating. To activate the cells, simply fill a bucket or sink with warm water; cold water will work as well, but warm works best from what we've experienced. Immerse the sheet in the warm water for about 90 seconds while scrunching the Techni Ice. Techni Ice recommends that you leave a thumb indentation in each cell during the swelling to allow room for expansion during freezing. Once the sheets have expanded they are ready to use! The sheets remain flexible when frozen and will not turn back to water as they thaw. Techni Ice lasts longer than ice and is less of a mess and it is easier to use than dry ice. It is also lighter than ice, making it great for use on-the-go!
