Biaxially oriented multilayered polypropylene film, process of preparation and use thereof

摘要

The invention relates to a co-extruded, biaxially oriented film which comprises a base layer essentially containing a polypropylene or a polypropylene mixture, and at least one outer layer containing olefinic polymers. The outer layer contains a combination of inorganic and/or organic particles and tertiary aliphatic amine of the formula I in which R<1> is a partially unsaturated aliphatic radical having at least 18 carbon atoms or an essentially saturated alkyl radical having 8 to 26 carbon atoms, and R<2> and R<3> are identical or different and are R<4>-CH2OH, in which R<4> is an essentially saturated C1-C6-alkyl radical. The invention also relates to a process for the production of the film and to the use of the film as a label.
