▎ 摘  要

NOVELTY - Coated polyamide film comprises a coating layer and a substrate layer. The coating layer is formed by coating the surface of the polyamide substrate layer with an acrylic coating liquid. The acrylic coating liquid includes silicone-modified acrylic resin, crosslinked polymethylmethacrylate powder and water. The mass ratio of the silicone-modified acrylic resin to crosslinked polymethylmethacrylate powder is 8-10:3-5. The substrate layer is a three-layer biaxially oriented polyamide film such as substrate layer (A), a substrate layer (B), and a substrate layer (C) arranged from top to bottom. The components of the substrate layer include polyamide, copolymer polyamide, dendrimer polyamidoamine, and black pigment. USE - Coated polyamide film used for aluminum-plastic composite film flexible package. ADVANTAGE - The film has good punching performance, no warping occurs after punching, and has good electrolyte resistance after the film is compounded with aluminum foil and polyethylene, and has good market application prospects.
