The invention relates to an opaque, multilayer polypropylene film which comprises at least one base layer containing polypropylene or a polypropylene mixture and fillers, and at least one top layer containing a mixture or blend of two components I and II. Component I essentially comprises a propylene homopolymer or a copolymer of an alpha -olefin having 2 to 10 carbon atoms or a terpolymer of an alpha -olefin having 2 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. Component II essentially comprises an HDPE having an MFI (50 N/190@C) of from greater than 1 to 50 g/10 min, measured in accordance with DIN 53 735, or a blend of two blend components A and B. Blend component A is essentially an HDPE having an MFI (50 N/190@C) of from greater than 1 to 50 g/10 min, measured in accordance with DIN 53 735. Blend component B is essentially a propylene homopolymer or a copolymer of an alpha -olefin having 2 to 10 carbon atoms or a terpolymer of an alpha -olefin having 2 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. The invention also relates to a process for the production of the multilayer polypropylene film and to the use of the film. |
