Vacuum metallized polyester film
Aluminized PET film is vacuum-vapor coated with aluminum on the surface of the film, which has high dielectric constant, excellent insulation, heat insulation, and strong tensile properties.
Vacuum metallization includes vacuum deposition, sputtering, ion plating and other methods to form various metallic and non-metallic thin films on the surface of products in a vacuum environment to achieve the effect of electroplating.
The main difference between electroplating and vacuum metallizing is cost. Vacuum metallization is usually more expensive and has a higher process complexity than electroplating.
