Laser paper

Laser aluminum spray paper (referred to as laser paper) is made by loading laser holographic patterns or text signals onto the surface of aluminum spray paper through molding. Vacuum aluminized paper can be divided into two production processes: direct method (paper surface aluminum spraying) and transfer method (film surface aluminum spraying). The direct method is to directly place paper in a vacuum aluminum plating machine for aluminum spraying. This method is limited to thin paper spray aluminum. The transfer method involves placing a PET film or laser PET film on coated paper or cardboard, and then peeling off the PET film (which can be reused multiple times). The aluminum molecular layer is transferred to the paper or cardboard through adhesive action. The transfer method can produce laser anti-counterfeiting vacuum aluminized paper or cardboard with any pattern and text that radiates radiance.
