Beschreibung
Zusammenfassung:	The utility model relates to the technical field of composite packaging films, in particular to a tensile wear-resistant fresh-keeping packaging film which comprises a tensile layer serving as a substrate, a stiffness increasing layer with a stiffness increasing effect and a toughening layer made of composite materials, and the stiffness increasing layer, the toughening layer and the tensile layer are sequentially overlapped from top to bottom. According to the tensile wear-resistant fresh-keeping packaging film disclosed by the utility model, the 0.012 mm PET film is compounded with the 0.017 mm PET film (the KPA layer and the VM-PA layer) film and the 0.07 mm high-strength CPP film, and the good stiffness of the PET film and the heat sealing performance and the high tensile performance of the CPP film are utilized; according to the tensile wear-resistant fresh-keeping packaging film disclosed by the utility model, a peanut bag made of the tensile wear-resistant fresh-keeping packaging film is not easy to we
