Vacuum evaporation coating machine aluminum plating film resistance curve test

Vacuum aluminum plating film has excellent blocking performance, in the case of does not require the transparent packaging, vacuum aluminum plating film is an excellent choice, and aluminum plating film cover good fragrance, with metallic luster, beautiful decoration, but due to the limitation of the ductility of the metal aluminum and aluminum plating technology, aluminized layer under extremely easily produce pinhole after rubbing, kneading or cracks, which affect the vacuum aluminum plating wet oxygen resistance performance and resistance performance. Light coating machine
Vacuum aluminum plating film is the deposition of composite membrane, the most representative products in the high vacuum conditions through the high temperature aluminum melt evaporation, aluminum vapor deposition agglomeration in the form a layer on the surface of plastic film, cut off about 35 ~ 40 nm thick layer, as the base material of the plastic film can be PE, PP, PET, PA, PVC, etc.
Splash control sputtering coating machine through the pinhole in the number of changes before and after the test sample in the rubbing test or blocking performance changes to determine the rubbing resistance material, can be designed for packaging and materials provide quantitative basis for practical application. Materials rub resistance can affect the packaging material in the process of the whole circulation barrier performance of stability, if due to material blocking layer song rubbing or poor rub resistance and lose its blocking effect, which can lead to product bad failure, then for packaging manufacturers, and product manufacturers losses are huge.
