Abstract: A coextruded, biaxially orientated film comprising a base layer, which comprises a polypropylene or a polypropylene mixture, and at least one top layer comprising olefinic polymers. The top layer comprises a combination of inorganic and/or organic particles and tertiary aliphatic amine of the formula I in which R1 essentially is an at least partially unsaturated alkyl radical having at least 18 carbon atoms or an essentially completely saturated alkyl radical having 8 to 26 carbon atoms and R2 and R3 are identical or different and are R4-CH2OH, in which R4 is an essentially saturated C1-C6-alkyl radical. The film is useful, for example, as a label or wrapping.

Abstract: Biaxially oriented polypropylene (BOPP) film with at least one base layer (A) contg. polypropylene (PP) is claimed, in which (a) the isotactic block length of the PP between two structural defects is more than 40 (statistical average); (b) the n-heptane- insol. component of the PP has an isotacticity (by C-NMR spectrometry) of at least 95%; and (c) the PP has a mol. wt. ratio Mw/Mn of less than 4 and contains less than 1% n-heptane-soluble component. Sealable film of this type has a gloss value of more than 90, pref. more than 105, and an opacity of less than 2.5, pref. less than 2.0. Non-sealable BOPP film has a gloss value of more than 120, pref. more than 130, and an opacity of less than 2.0, pref. less than 1.8. Also claimed is a process for the prodn. of this BOPP film, by (i) heating, compressing and melting the polymers for the different layers in extruders; (ii) combining the different melts; (iii) extruding through a sheet die; (iv) cooling and compacting the film on a take-off roll; and (v) orienting the film by stretching in the machine direction by a factor of (3:1)-(9:1) and in the transverse direction by a factor of (4:1)-(12:1).

Abstract: A biaxially oriented polypropylene film is described. The base ply of the film essentially consists of a polypropylene prepared by means of a metallocene catalyst. This polypropylene is distinguished by a mean isotactic block length of greater than 40, an n-heptane soluble fraction of less than 1% and a ratio of the weight average molecular weight Mw to the number average molecular weight Mn of less than 4.

Abstract: The invention relates to an oriented multilayer polyolefin film which comprises a polyolefinic base layer and at least one heat-sealable top layer. The heatsealable top layer contains at least one amorphous polymer which is in the top layer in the form of separated particles. The invention also relates to a process for the production of the multilayer polyolefin film and to the use of the film.
