Thermal Barrier
Trapped air is the key. Our patented manufacturing process allows us to seal every edge of every pack.
We have developed lightweight yet wide material that is weak without sealing. Seal the edge however, and the product is transformed, with more air trapped inside. This trapped air in both tray and lid acts like double glazing, restricting the flow of temperature very effectively. There is a significant wall of trapped air around a pallet of fish packed in CoolSeal boxes.
