The invention relates to a multilayered polypropylene film comprising at least one base layer containing polypropylene or a polypropylene mixture and resin, and at least one top layer containing a mixture or blend of two components I and II. The component I essentially contains 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 said homopolymers, copolymers and terpolymers or a blend of two or more of said homopolymers, copolymers and terpolymers, optionally mixed with one or more of said homopolymers, copolymers and terpolymers. Component II essentially contains 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 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 said homopolymers, copolymers and terpolymers or a blend of two or more of said homopolymers, copolymers and terpolymers. The film is matt. |
