Speciallity
Technological process
The aluminum plating process of plastic film is usually plated by direct plating, and the aluminum coating is directly plated on the surface of the substrate film. There is no need for surface treatment before aluminum plating of BOPET and BOPA film substrate, and can be directly steamed. BOPP, CPP, PE and other non polar plastic film, steamed in need on the film surface corona treatment or coating adhesive layer before plating, the surface tension reached 38-42 dyne / cm or has good adhesion. In the process of evaporation, the film is placed in a vacuum chamber, and the vacuum chamber is closed. When the vacuum level reaches (4 * 10 4mba), the evaporation boat will rise to 1300 ~ 1400 C, then the aluminum wire with purity of 99.9% will be sent to the evaporation boat continuously. Adjust the rolling speed, winding speed, wire feeding speed and evaporation volume, open the cooling source, make the aluminum wire continue to melt and evaporate on the evaporating boat, and then form a bright aluminum layer on the surface of the moving film, that is, the aluminum plated film.
 
Brief Introduction
Metallic bubble mailers
Product description:
Metallic bubble mailers is made of low density polyethylene (LDPE). The features of low cost, large volume, good waterproof performance.
