NOVELTY - A composite BOPET film claimed by the utility model provided by some embodiments, BOPET base film from up to down in turn, PCT, a graphene layer, anti-ultraviolet, anti-oxidation polyurethane layer and an antibacterial and skid-proof silicon layer. No flame retardant layer can improve the heat distortion temperature of the film, the composite BOPET film has flame retardant property, heat conducting graphene layer can accelerate the composite BOPET film and improve the uniformity of heating and ultraviolet resistance, characteristic improved anti-ultraviolet, anti-oxidation performance, and anti-ultraviolet, anti-oxidation polyurethane layer further improves the softness of the composite whole BOPET film, through the antibacterial, anti-skid organosilicon layer such that composite BOPET film with antibacterial and anti-oxidation polyurethane layer so that the composite BOPET film. In addition, the thickness of the BOPET base film is 15m to 75m such that composite BOPET film with a reasonable thickness, further widening the application range of the composite BOPET film.
