Technical information

Sealed Edge Technology

  • Trapped air is the key. Air is trapped in the flutes with our exclusive manufacturing process which allows us to seal the open ends and traps the air inside, to create an insulative layer and a leak-proof package.
  • The polypropylene flute board employed is lightweight and strengthened through the process of heat sealing the edges.
  • CoolSeal includes our inter-locking stacker range, from 3kg up to 25kg. All designed for perfect palletising and logistics.



Stericor™is an Antimicrobial Plastic Sheet that is FDA approved. Stericor™ can be applied to sealed-edge Corflute® packaging when extra protection is required for applications like medical and food packaging items.

Cleaner & more durable: It is inherently cleaner and more durable plastic product. These invaluable features make it perfect for use in hygiene critical, high-traffic environments such as hospitals, food processing facilities and schools.

Permanent & cost-effective: Provides protection is a permanent, cost-effective solution that remains active for lifetime. It restricts  typical microbial and fungal degradation. Remains effective even if a treated object is nicked or scratched. The technology does not wash off, wear away.

Stops the stink! Microbes can cause noxious odours. Stericor™ naturally reduces odours and improves product appeal for consumers. It minimizes the presence of stain and odor-causing bacteria.


Everything we make is invited to be brought back for recycling and reuse in products for tomorrow.

Corex Recycling works alongside the factory that designs and produces CoolSeal packaging.
