Metalized PET film laminating packaging plastic roll film

Aluminum coating is a composite soft packaging material formed by using a special process to coat a thin layer of metal aluminum on the surface of plastic films. The most commonly used processing method is vacuum aluminum coating, which is to melt and evaporate the metal aluminum under high vacuum at high temperature, causing the vapor deposition of aluminum to accumulate on the surface of plastic films, thereby giving the plastic film a metallic luster.
