Aluminized films mainly include polyester aluminized film (VMPET) and CPP aluminized film (VMCPP). The function of aluminum plating on the surface of the film is to block light and prevent ultraviolet radiation, which not only prolongs the shelf life of the contents, but also improves the brightness of the film. It replaces aluminum foil to a certain extent. , aluminized film is widely used in composite packaging.
PE has thermal bonding properties. After the VMPET/VMCPP is coated with a layer of PE, it can be used to bond other materials .
