Zusammenfassung:	The utility model relates to the technical field of composite films, in particular to an anti-extension composite film which comprises a base material layer, and a bottom layer is arranged on the lower surface of the bottom end of the base material layer. The reinforcing layer is compounded on the surface of the top end of the base material layer, the anti-bending layer is compounded on the surface of the top end of the reinforcing layer, the anti-ultraviolet film layer is compounded on the surface of the top end of the anti-bending layer, the surface coating is compounded on the surface of the top end of the anti-ultraviolet film layer, the bottom layer is compounded on the surface of the bottom end of the base material layer, and the composite film layer adopts a dry type compounding method. Wherein the base material layer is a main structural layer in the composite film, and the polypropylene film has the main advantages that the barrier property of the polypropylene film is superior to that of a high-dens
