Aluminized film

The aluminized film is obtained by evaporating a high-purity aluminum wire into a gaseous state at a high temperature (1100 to 1200 ° C) by a vacuum aluminum plating process, and then the molten aluminum molecules are deposited on the surface of the plastic film to form a bright light when the plastic film passes through the vacuum evaporation chamber. Metallic film.

The most widely used aluminized films are mainly polyester aluminized film (VMPET) and CPP aluminized film (VMCPP).

The surface of the film is coated with aluminum to prevent light and ultraviolet radiation, which not only prolongs the shelf life of the content, but also improves the brightness of the film. It replaces the aluminum foil to a certain extent, and has the advantages of low cost, good appearance and good barrier property.
