In addition to the excellent physical and mechanical properties of ordinary polyester film, aluminized PET film also has optical properties, such as good transparency, low haze, and high gloss. It is mainly used for vacuum aluminized products. The film is a mirror after aluminizing, which has a good packaging and decoration effect; it can also be used for laser anti-counterfeiting base film.
Transfer film is also called thermal transfer film. The characteristics of this transfer film are high tensile strength, good thermal stability, low thermal shrinkage, smooth and clean surface, good peelability, and can be used repeatedly. It is mainly used as a carrier for vacuum aluminization, that is, after the PET film is placed in a vacuum aluminizing machine for aluminum plating, the glue is coated with the paper, and then the PET film is peeled off, and the aluminum molecular layer is transferred to the surface of the cardboard through adhesion. The so-called aluminized cardboard is formed.
