Aluminum metallized PP films are made by vapor phase deposition of aluminum onto the film in a vacuum and have a high dielectric constant, excellent insulating and thermal insulation properties. Polypropylene (PP) is a semi-crystalline thermoplastic known for its high impact resistance, strong mechanical properties, and resistance to a wide range of organic solvents and acids and bases.



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.

Physical vapor deposition (PVD) is a process used by many manufacturers to coat metals such as titanium and stainless steel. The technique involves “shooting” metal onto another metal at high temperatures, transforming the material from a vapor phase to a solid film.

We can process a wide range of materials, including non-metallic materials such as PEN, PET, PPS, PP, PI, PTFE, EPTFE, etc., as well as a variety of metal materials such as aluminum, copper, gold, silver, nickel, tin and indium.

Typically, our products have a width ranging from 0.5 meters to 1.4 meters and lengths between 1000 and 20000 meters per roll.
