NOVELTY - The utility model model claims a plastic film, the plastic film winding at the outer side of the supporting cylinder, the plastic film is composed of a first graphene layer, a connecting layer and a second graphene layer, the first graphene layer is attached to the inner surface of the plastic film, the lower end face of the first graphene layer is connected with a connecting layer and a second graphene layer in turn from top to bottom, the connecting layer comprises a polyvinyl chloride layer, polyethylene, polypropylene and polystyrene, the lower end face of the polyvinyl chloride layer is connected with the polyethylene; the lower surface of the polyethylene is orderly adhered with polypropylene and polystyrene, the surface and lower surface respectively of the plastic film is tightly attached with an upper and surface surface layer. The high tensile puncture resistant plastic film improves the whole tensile property and anti-puncture performance, prolongs the service life of the whole, and increases the friction force of the connection between the plastic film, prevents the skid phenomenon when using.
