发明名称 BIAXIALLY ORIENTED POLYPROPYLENE FILM FOR METALLIZING APPLICATIONS
摘要 A metallizable, heat-sealable, biaxially oriented multi-layer film for metallizing applications is described which comprises a base layer comprising polypropylene, a first polyolefinic heat-sealable surface layer and a second polyolefinic metallizable surface layer. The second polyolefinic metallizable surface layer comprises a propylene-ethylene copolymer, which has an ethylene content of 1.2 to 2.8% by weight, a distribution factor VF greater than 10, an enthalpy of fusion .DELTA. Hm greater than 90 J/g and a thermo-oxidation temperature Tox greater than 240.degree.C.
