Abstract
The invention belongs to the technical field of packaging materials, in particular to a film for packaging. The biaxially oriented polypropylene adhesive-free film is characterized by consisting of a surface layer, a core layer and a secondary surface layer, wherein the core layer is positioned between the surface layer and the secondary surface layer; the surface layer, the core layer and the secondary surface layer are co-extruded and form a whole by biaxial tension; the material of the surface layer consists of the following components in percentage by weight: 90 percent of low-density polythene, 5 percent of anti-adhesive agent and 5 percent of slipping agent; the core layer is made of low-density polythene, metallocene polyethylene and ethylene propylene diene methylene; and the secondary surface layer is made of ethylene-polythene copolymer, paraffin, hydrogenated resin, low-density polythene and antioxidant. The invention has the characteristics of low compound temperature (60-95 DEG C) with paper and favorable puncture resistance.
