Sonoco ThermoSafe Refrigerants
PolarPack, U-tek, and Moisture Guard Gel Packs
Polarpack, U-tek and Mositure Guard gel packs provide thermal protection for the shipment of temperature sensitive products. Available in a broad selection of styles and a multitude of sizes.
PolarPack standard gel packs are an economical alternative wet ice. U-tek phase change materials provide longer protection than standard gel packs to help maintain critical temperatures for extended periods of time. The unique phase change formula is ideal for products requiring frozen temperatures or extreme cold that do not tolerate dry ice or carbon dioxide. Moisture Guard gels feature a multi-layered exterior which minimizes surface condensation and protects product from moisture damage. The outer film layer assures products arrive in top condition by absorbing condensation.
PolarPack Foam Bricks
The semi-rigid PolarPack Foam Bricks never change shape during freezing, thawing or transit. These foam bricks maintain designated packing configurations throughout the trip. Each brick is vacuum sealed for consistent weight and shape.
PolarPack Rigid Bottles
ThermoSafe™ blow-molded rigid plastic bottles are the most durable packs. These bottles are multi-purpose, can be reused and withstand rugged warehouse packaging environments.
PureTemp Phase Change Materials
PureTemp Phase Change Material- The industry's only USDA Bio Preferred phase change material that liquefies or solidifies at precise temperatures. PureTemp bio-based PCMs are 100% renewable and environmentally-friendly. Even after thousands of thermal cycles, tests show PureTemp experiences, no thermal degradation.PureTemp is engineered to react to a precise temperature, from -40° to +37°C, and to operate in a very narrow temperature range. PureTemp comes in two formats: foam bricks and hard bottles.
