▎ 摘  要

NOVELTY - Paper-plastic composite bag comprises paper layer and plastic layer, where the plastic layer is placed on the surface of the paper layer. USE - Used as paper-plastic composite bag. ADVANTAGE - The paper-plastic composite bag: has excellent heat resistance, flame retardant and anti-aging performance. The method: is suitable for mass production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing (s1a) mixing acrylonitrile-butadiene-styrene plastic with styrene-N-phenylmaleimide-maleic anhydride, high rubber powder, N,N'-hexamethylene bis-stearamide evenly, After being placed in a twin-screw extruder for granulation at 240-270degreesC, the compound flame retardant is obtained with decabromodiphenylethane and antimony oxide in a twin-screw extruder at 180-210degreesC for granulation
