The utility model discloses a multilayer film structure based on bright surface paper, including the transparent layer, bright surface paper, adhesive layer and double glue base paper of up and down distribution, the transparent layer includes the first transparent adhesive film and second transparent adhesive film that different anti -fake marks are printed, and the first transparent adhesive film and second transparent adhesive film all are glued on the bright surface layer, and the anti -fake mark of both is not blocked each other, and the adjacent place of first transparent adhesive film and second transparent adhesive film exists the overlapping area, and both fixed connection. The utility model discloses through gluing the first transparent adhesive film and second transparent adhesive film on the bright surface layer of bright surface paper, does not influence the original luster and aesthetic feeling of bright surface paper, and through the anti -fake mark of first transparent adhesive film and second transparent adhesive film, increases the anti -fake function, in addition, because first transparent adhesive film and second transparent adhesive film fixed connection, improve the bonding strength of first transparent adhesive film and second transparent adhesive film and bright surface paper, and the combination of different anti -fake marks can improve the difficulty of counterfeiting, and easily consumer identification.

This invention relates to a titanate nanomaterial composite polypropylene film and its preparation method, specifically providing a BOPP composite film masterbatch, which comprises modified titanate nanotubes, modified titanate nanowires, or modified titanate nanosheets, wherein the modified titanate nanotubes are titanate nanotubes adsorbed with surfactants, the modified titanate nanowires are titanate nanowires with surfactants adsorbed on their surfaces, and the modified titanate nanosheets are titanate nanosheets with surfactants coated on their surfaces.
