A4 sample of PET coating 40 g/m², printed in 4 C offset on Invercote GP 230 g/m² combined with the product specification.
Paperboard with polyethylene terephthalate (PET) coating is suitable for packaging applications where the fat barrier and temperature resistance are important. It is amorphous and sealable.
At temperatures around 70°C it is transformed successively to a partly crystalline state with a melting point of approximately 260°C. This means that the heat sealing properties of the package will deteriorate when heated. It can be used for food products that are cooked in the pack and/or reheated in a microwave or conventional oven.
