Metalized film/Aluminized film introduction

Aluminized film, through the vacuum aluminum plating process, high-purity aluminum wire is evaporated into a gaseous state at high temperature (1100-1200C), and then when the plastic film passes through the vacuum evaporation chamber, the gaseous aluminum molecules precipitate on the surface of the plastic film to form a bright metallic color For thin films, the thickness of the aluminum layer is usually between 320 and 480 angstroms.

, Aluminized film production process:

Substrate unwinding, vacuuming, heating evaporation boat, aluminum wire feeding, evaporation, cooling, thickness measurement, flattening, and winding 2. Classification of aluminized film:

PET aluminized film, CPP aluminized film, OPP aluminized film, PVC aluminized film, PE aluminized film, currently the most commonly used in the market are PET aluminized film and CPP aluminized film. Three, aluminized film effect:

1. Aluminized film is used for shading and UV protection, and is mostly used for drying and puffing food packaging such as biscuits and the outer packaging of some medicines and cosmetics

2. The light reflectance of the aluminized film can reach more than 92%, and it is mostly used for heat insulation materials.

3. Conventional thickness of PET aluminized film: 6u/8u/12u/18u
