Reliable U-TEK® refrigerant gel packs simplify shipping temperature-sensitive materials.


U-TEK®'s are a clean, convenient alternative to wet or dry ice. When used to replace wet ice, U-TEK®'s eliminate the wet mess, returning to a gel after thawing. Each pack can be used repeatedly and is harmless to handle. U-TEK®'s are available both in -10°F and +30°F formulations so they're ideal for use with either refrigerated or frozen products.

Constructed of a laminated metallized polyethylene film, U-TEK®'s foil packaging is heat-reflective, durable, and puncture-resistant.

U-TEK®'s significantly extend the safe shipping time for temperature sensitive materials. They are the perfect shipping partners for our insulated containers.

Test Results


In separate trials, Polyfoam U-TEK® models 414 (+30°F) and 420 (-10°F) were placed in model 411 insulated containers (with 1½" wall thickness) at temperatures between 70°-74°F. The +30°F formula kept payload temperatures at or below 42°F for more than 50 hours. The -10°F formula kept payload temperatures at or below 32°F for more than 40 hours.
