▎ 摘　　要

NOVELTY - Cigarette film comprises functional layer, core layer and secondary functional layer, where the core layer is located between functional layer and sub-functional layer, the mass ratio of functional layer, core layer and secondary functional layer is (3-4): 15:(3-4), the functional layer is prepared using 97-98.3 %mass copolymerized ternary polypropylene, 1-2 %mass antioxidant and 0.5-1 %mass graphene, the core layer is prepared using 87-92 %mass homopolymerized polypropylene, 5-10 %mass petroleum resin, 1-2 %mass internal lubricant, 0.5-1 %mass antioxidant, 0.5-2 %mass anti-UV agent and 1-3 %mass migration toner, and the secondary functional layer is prepared using 0.5-3 %mass graphene, 0.5-2 %mass antioxidant, 95-98 %mass homopolypropylene, 0.2-0.5 %mass benzophenone and 0.2-0.5 %mass diphenylamine. USE - As cigarette film. ADVANTAGE - The cigarette film has strong anti-UV and anti-yellowing ability.
