    摘要： The present invention relates to an at least single-layer, biaxially oriented film support for magnetic recording media which is predominantly composed of crystallizable polyester, having a thickness in the range from 1 to 40 &mgr;m. The film has, over its total roll length and roll width and after it has been made up into customer rolls, an electrostatic charge build-up which is in the range from −80 kV/m to +80 kV/m, the contact pressure at the roll cutters during make-up being set in the range from 300 N/m to 350 N/m. The film is drawn between electrical discharge means, which are arranged close to the roll, along the film path in the make-up machine, and is particularly suitable for high-quality audio, video or computer tapes and for floppy disks or thermal tapes.

    摘要： 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 .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, 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 .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 has a silk-matt finish.
