What is an aluminized composite film?

- Jan 10, 2019-

The aluminized film is also called a metal film or a vacuum aluminized film. The aluminum vaporized atom is solidified on the surface of the film by vacuum evaporation on a plastic film to form an aluminum-plated film having an aluminum metallic luster. Its appearance is as attractive as aluminum plating, but the packaging cost is much lower than aluminum foil. The vacuum evaporation process has three types: single chamber method, double chamber method and continuous vapor deposition method.


The main equipment of vacuum aluminum plating film is aluminum plating machine, which mainly includes vacuum tank, winding system, winding drive system, evaporation enthalpy, vacuuming equipment, cooling tower drum, numerical control operating system and accessory equipment. Vacuum evaporation can also be used to evaporate low-boiling metals such as aluminum, nickel, lead, etc. Recently, silicon oxide and silicon nitride can also be deposited on plastic films to form vapor-deposited materials with high barrier properties. The cooling drum has a single strand and a double strand.
