Introduction to PET Coated Paperboard
PET Coated Cardboard is a high-performance paperboard laminated with a layer of Polyethylene Terephthalate (PET) film. This coating enhances the base board with moisture resistance, heat sealability, and surface gloss, making it an excellent material for food-grade packaging, high-barrier cartons, and specialty print applications.
The PET layer not only acts as a barrier but also supports vibrant printing, allowing brands to combine visual appeal with functional durability. PET-coated cardboard is recyclable in many regions and often used as a more sustainable alternative to plastic trays and containers.
