Formulated from nontoxic materials, these reusable Koolit® refrigerant gel packs maintain the thermal profile of temperature-sensitive products safely and more efficiently than ice.

The 500 Series gel packs contain a CMC-based gel formation, while the 500-ST Series packs contain a suppressed temperature gel formation. Both feature a puncture-resistant laminate foil film exterior. The 600 Series gel packs consist of a long-lasting polymer gel formulation in a 5mil thick white polyethylene pouch. They are ideal for one-time use or disposable applications.

Use the 0°C (32°F) gel formulation for the shipment of refrigerated products, and the –23°C (–10°F) formulation for products that need to stay below freezing temperatures.
