Abstract (en)
[origin: DE19718199A1] The invention relates to a heat-sealable composite film with a biaxially stretched polypropylene base layer, a modified polyolefin adhesion-promoting layer, an ethylene and carbon monoxide copolymer gas barrier layer and an olefin polymer heat-seal layer. The base layer has optionally at least one monoaxially oriented layer combination on at least on one of its surfaces, comprising: A) an olefinic homo, co or terpolymer heat-sealable outer layer; B) a modified polyolefin adhesion-promoting layer; C) a one or more olefin or carbon monoxide (polyketone) gas barrier layer; D) a modified polyolefin adhesion-promoting layer and E) a polyethylene layer and an ethylene polymer with at least 3 wt. % ethylene. The base layer has optionally layer A, a combination of layers A-E, A-D or B and C on at least one of its surfaces.
