Preparation method of double-color imitation aluminum laminated film

The invention discloses a preparation method of a double-color imitation aluminum laminated film, and belongs to the technical field of printing and packaging. The method comprises the following steps: mixing metal particle powder with varnish to form uniform metal ink; printing metal ink on the plastic film, and drying the metal ink; and coating a layer of photocuring gloss oil on the surface of the metal ink, and curing to form a film after ultraviolet irradiation. According to the invention, the metal ink is utilized to realize the metallic luster of the aluminum laminated film, and meanwhile, the production efficiency far superior to that of the aluminum laminated film is effectively realized due to the quick drying of the ink; the printing of the metal printing ink can simultaneously realize the visual effects of various metal luster, so that the designability is increased; and in addition, due to introduction of the light-cured gloss oil, the light-cured gloss oil can be stably combined with metal ink i
