The purpose of the aluminized composite membrane and characteristics

Aluminum plating film is through vacuum aluminum plating machine on special substrate film, using high temperature aluminum gasification precipitation principle to carry on the production of thin film evaporation, aluminum plating film with a sparkling appearance, similar to the aluminum foil, is generally the base material of aluminium coated mainly has three categories: OPP, CPP, PET, have certain barrier performance, aluminum plating film is better than before aluminum plating. USES: vacuum aluminum plating film due to both has the characteristic of plastic film, but also has the characteristics of metal is a kind of cheap and beautiful packaging materials, excellent performance, strong practicability, therefore, aluminum plating film has been widely used in food, medicine, chemical products such as packaging, such as fast food, tea, coffee and cosmetics packaging. Characteristics: a, and compared greatly reduced the amount of aluminum foil, save the energy and materials, reduce the cost. Composite aluminum foil thickness of 7 ~ 9 microns, the thickness of aluminum and aluminum plating film to 0. 04 mu m or so, the aluminum consumption is about 1/200 of the aluminum foil, and the production speed can be as high as 700 m/min. Second, it has excellent folding resistance and good toughness, rarely pinhole and split, no song cracking phenomenon, so the gas, water vapor, smell, such as light barrier property of the improvement. Three, metal luster, excellent optical reflectivity of 97%; And can form color film coating processing, its decorate effect is inferior to the aluminum foil. Part four, shield type can be used for aluminium, for any design or transparent window, can see inside. Five, aluminized layer conductive performance is good, can eliminate electrostatic effect. After six, for printing, composite processing and has good adaptability.
