Abstract: The invention relates to a polyolefinic multilayer film which comprises a base layer containing polypropylene, and at least one outer layer. The outer layer contains a low-crystallinity C3/C4-olefin resin composition and has a minimum heat-sealing temperature of less than 84@C. The invention also relates to a process for the production of the multilayer film and to the use of the film.

Abstract: 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 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 and R are identical or different and are R -CH2OH, in which R 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.

Abstract: The disclosed oriented polyolefin film contains at least one voided layer. The voided layer contains an amorphous void- initiating polymer which, after orienting, is present as a separate particle inside the void. In the process for producing the polyolefin film, a molten blend comprising an olefin polymer and the amorphous polymer is extruded through a die at an extrusion temperature above the glass temperature or Vicat softening point of the amorphous polymer, the resulting film is drawn off on one or more rollers, and is then subjected to stretch orientation, followed optionally by thermofixing and a surface treatment.

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 heat-sealable 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.

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 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%, (c) the mol. wt. ratio Mw/Mn is less than 4, (d) the PP contains less than 1% n-heptane-soluble component, and (e) the base layer has elastic moduli of more than 2400 and more than 4800 N/mm in the machine (longitudinal) and transverse directions respectively. Also claimed is a process for the prodn. of this BOPP film, by heating, compressing and melting the polymers for the different layers in extruders, combining the different melts, extruding through a sheet die, cooling and compacting the film on a take-off roll, and 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: 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%, (c) the PP has a mol. wt. ratio Mw/Mn of less than 4 and contains less than 1% n-heptane-soluble component, and (d) the film has a tear strength of more than 15 N/(mm film thickness) in both the machine (longitudinal) and transverse directions. Also claimed is a process for the prodn. of this BOPP film, which involves 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).
