High Performance Insulated Packaging

Woolcool insulated packaging has been independently proven to keep products within the 2°c and 8°c from 24 hours to more than 72 hours.

To send out chilled products by post, courier or regular delivery van, you’re going to need ice packs - although Woolcool insulated packaging requires much fewerthan you’d need in polystyrene boxes.

Sorbafreeze sheets are ultra thin because they are filled with a clever polymer powder which are simply soaked in water to hydrate and frozen into ice sheets when required.
