A multilayer polypropylene film is disclosed that has at least one base layer containing polypropylene and at least one outer layer containing a mixture of two mixture components I and II. Mixture component I is essentially a polypropylene homopolymer or a copolymer of ethylene and propylene or ethylene and butylene or propylene and butylene or ethylene and another a-olefin having 5 to 10 carbon atoms or propylene and another a-olefin having 5 to 10 carbon atoms or a terpolymer of ethylene and propylene and butylene or ethylene and propylene and another a-olefin having 5 to 10 carbon atoms or a mixture of two or more of said homopolymers, copolymers and terpolymers or a blend of two or more of said homopolymers, copolymers and terpolymers, if desired mixed with one or more of said-homopolymers, copolymers and terpolymers. Mixture component II is essentially an HDPE or a blend of two blend components A and B. Blend component A is essentially an HDPE. Blend component B is essentially a polypropylene homopolymer or a copolymer of ethylene and propylene or ethylene and butylene or propylene and butylene or ethylene and another a-olefin having 5 to 10 carbon atoms or propylene and another a- olefin having 5 to 10 carbon atoms or a terpolymer of ethylene and propylene and butylene or ethylene and propylene and another ac-olefin having 5 to 10 carbon atoms or a mixture of two or more of said homopolymers, copolymers and terpolymers or a blend of two or more of said homopolymers, copolymers and terpolymers.
