Aluminum plating film, through the vacuum aluminum plating process will be high purity aluminum wire at high temperature (1100~1200℃) evaporation into a gaseous, after the plastic film through the vacuum evaporation chamber, gaseous aluminum molecules precipitate to the surface of the plastic film and form a bright metal color film, aluminum layer thickness is usually between 320~480 emm.
Aluminum film production process:
Base material unwinding → vacuum pumping → heating evaporation boat → aluminum wire feeding → evaporation plating → cooling → thickness measurement → flattening → coiling.
Aluminum plating film classification:
PET aluminized film, CPP aluminized film, OPP aluminized film, PVC aluminized film, PE aluminized film, PET aluminized film and CPP aluminized film are commonly used in the market.
Characteristics:
1, aluminized film shading, anti-ultraviolet radiation, mostly used in biscuits and other dry, puffed food packaging and some medicine, cosmetics packaging.
2, aluminized film light reflectivity can reach more than 92%, mostly used for heat insulation materials.
3, PET aluminum plating film conventional thickness: 6U / 8U / 12U / 18U.
