Sonoco™ ThermoSafe U-tek™ Gel Pack

Phase Change Material (PCM) gel pack for shipping temperature-sensitive materials.

Sonoco™ ThermoSafe U-tek™ Ice
Cushions fragile shipments, and won’t dilute ice baths or damage samples. Remains frozen longer than regular ice, without the melting mess.

Sonoco™ ThermoSafe PolarPack™ Foam Bricks
Foam brick ice packs never change shape during freezing, thawing or transit, enabling superior surface contact for more consistent temperature control. Refrigerant bricks are vacuum-sealed for consistent weight and shape.
