Our ice packs offer several advantages over dry ice. Safety: Dry ice is dangerous to handle, can contain harmful contaminants and is considered a hazardous material for air and water transportation. In contrast, our Enviro Ice -12°C packs offer similar refrigerant properties in a formula that’s safe to handle, 100% food-safe and nontoxic.  Control: Dry ice is highly unstable, which introduces additional risk and complexity to cold chain operations. Using more stable gel ice packs instead allows easier refrigerant inventory control.  Sustainability: Enviro Ice provides reliable performance along with industry-leading advantages in biodegradability and recyclability.
