Biaxially-oriented multilayer polyolefin film with a silk-matt finish, process for its preparation and use thereof |
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.
