Opake, matte Polypropylen-Mehrschichtfolie, Verfahren zu ihrer Herstellung und ihre Verwendung

摘要

The invention relates to an opaque, matt multilayer polypropylene film comprising at least one base layer and at least one interlayer and a top layer applied to this interlayer. The base layer contains polypropylene and fillers. The interlayer contains a mixture or blend of two components I and II. Component I is a propylene homopolymer or a copolymer of alpha -olefins having 2 to 10 carbon atoms or a terpolymer of alpha -olefins having 2 to 10 carbon atoms or a mixture or blend of said polymers. Component II is an HDPE or a blend of HDPE and a propylene homopolymer or a copolymer of alpha -olefins having 2 to 10 carbon atoms or a terpolymer having 2 to 10 carbon atoms. The top layer essentially contains a propylene homopolymer or a copolymer of alpha -olefins having 2 to 10 carbon atoms or a terpolymer of alpha -olefins having 2 to 10 carbon atoms or a mixture or blend of said polymers.
