Problems solved by technology

[0003] The biaxially oriented polypropylene film has many characteristics such as light weight, good transparency, moisture resistance and oxygen resistance, good air tightness, and toughness. However, the aging resistance of the biaxially oriented polypropylene film prepared by the prior art is average, especially in When used outdoors, after a long period of aging, the mechanical properties will be greatly reduced, resulting in a shortened lifespan

Description

technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to a method for preparing an aging-resistant BOPP film. Background technique [0002] Biaxially oriented polypropylene (BOPP) films, also known as oriented polypropylene films, are used in various technical applications such as packaging, tapes or capacitor films. [0003] Biaxially oriented polypropylene film has many characteristics such as light weight, good transparency, moisture resistance and oxygen resistance, good air tightness, and toughness. When used outdoors, after a long period of aging, the mechanical properties will be greatly reduced, resulting in a shortened lifespan. Contents of the invention [0004] The object of the present invention is to provide a method for preparing an aging-resistant BOPP film aiming at the existing problems. [0005] The present invention is achieved through the following technical solutions: [0006] A method for pr...
