High-Adhesion Metallized PET Film
Cailong High Adhesion Metallized PET Film is a vacuum-metallized polyester film designed for structures where metal-layer bonding is critical. It is used in flexible packaging, extrusion lamination, labels and industrial laminates that may undergo demanding printing, coating or converting steps. Its main advantage is improved adhesion between the aluminum layer and PET substrate, helping reduce peeling and delamination risks during processing.
Properties:
High barrier and ultra-high barrier properties:
significantly improve the flavor retention and preservation performance of food,and extend the shelf life of food;High adhesion of
aluminumlayer:Adhesion≥2.5N/15mm
More environmentally friendly and meet the requirements of GB4806.7,FDA,EU, reach,ROHS,etc;
Application:
Flexible Packaging Lamination;Application and packaging of electronics, decorative materials,labels,cosmetics and metal products;
