ABSTRACT:
The invention relates to a multilayer polypropylene film which contains at least one base layer containing polypropylene or a polypropylene mixture and resin, and at least one outer layer which contains a mixture or a blend of two components I and II. Component I essentially comprises a propylene homopolymer or a copolymer of ethylene and propylene or ethylene and butylene or propylene and butylene or ethylene and another .alpha.-olefin having 5 to 10 carbon atoms or propylene and another .alpha.-olefin having 5 to 10 carbon atoms or a terpolymer of ethylene and propylene and butylene or ethylene and propylene and another .alpha.-olefin having 5 to 10 carbon atoms or a mixture of two or more of the homopolymers, copolymers and terpolymers or a blend of two or more of the homopolymers, copolymers and terpolymers, if desired mixed with one or more of the homopolymers, copolymers and terpolymers. Component II essentially contains an HDPE or a blend of two components A and B. Blend component A is essentially an HDPE. Blend component B is essentially a propylene homopolymer or a copolymer of ethylene and propylene or ethylene and butylene or propylene and butylene or ethylene and another .alpha.-olefin having 5 to 10 carbon atoms or propylene and another .alpha.-olefin having 5 to 10 carbon atoms or a terpolymer of ethylene and propylene and butylene or ethylene and propylene and another .alpha.-olefin having 5 to 10 carbon atoms or a mixture of two or more of the homopolymers, copolymers and terpolymers or a blend of two or more of the homopolymers, copolymers and terpolymers. The film is used in twist wrapping.
