According to its production process, it can be divided into two types: direct method and transfer method

The direct method is to pre coat the surface of the paper to improve its smoothness and brightness, and then directly place the paper in a vacuum aluminum plating machine for aluminum plating. This method has high requirements for paper, and is suitable for 40~120g/m2 Coated paper, whiteboard, cardboard and other paper types. The transfer method uses PET and BOPP films as transfer substrates, and undergoes coating, coloring, aluminum spraying, lamination, peeling, and other processes to transfer the aluminum sprayed molecular layer with metallic luster to the surface of paper or paperboard through adhesive action.

The aluminum coated paper produced by the transfer method is bonded to the paper using PET film transfer. The aluminum film has good flatness, strong metallic luster, and high smoothness, making it more suitable for packaging and printing. Compared to the direct method, the transfer method has the following characteristics: (1) the adhesion of the aluminum layer is firm and reliable, and it can produce aluminum coated paper of any thickness (40-450g) of paper or paperboard. (2) the flatness of the PET film can be fully utilized to make the paper surface more shiny with metal luster and greatly improve the appearance quality; (3) We can produce laser anti-counterfeiting vacuum aluminized cardboard with various patterns.
