U Chill Components: Foil Bubble Insulation System

The U CHILL foil system used with gel packs have been designed and validated to keep your products chilled below +5°C for 72 hours in the winter & 48 hours in the summer. The temperature controlled systems consist of a white double walled corrugated carton & a two part air infused reflective insert.

Our packs have been designed solely to replace polystyrene with a cost effective, fully functional, and aesthetically attractive alternative. They have been designed specifically to maximise the number of layers of airlock insulation with the fitment’s fully glued to the box to ensure the product is both watertight and temperature controlled.

Although we can design this product to fit your needs, we stock 4 sizes: small, medium, large and extra large.
