In the bronzing process that requires lamination, people often worry that the gold foil will be easily wiped off and then hot stamped and then laminated. This can easily lead to:
A. The film (especially the matt film) will destroy the luster of the surface of the electrodeposited aluminum. It is not appropriate to use a water-soluble glue to cover the film. Otherwise, the surface of the electrodeposited aluminum will be blackened, and the powder will easily stick to the edges of the picture and cause the phenomenon of hair weakness.
B. After the bronzing, the dent is caused by the pressure, and the glue is not easy to penetrate the surface of the galvanized aluminum, which can easily cause separation of the OPP and the paper at the bronzing office and affect the product quality. The correct process is to apply foil and then hot stamping, choose the matching of aluminum and OPP.
