Abstract: A biaxially oriented polypropylene film is described. The base ply of the film contains at least 90% by weight 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.

Abstract: The disclosed oriented polyolefin film contains at least one voided layer. The voided layer contains an amorphous voidinitiating 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 disclosed heat-sealable, layered film comprises a polyolefinic base layer and at least one outer layer. The outer layer comprises a propylene-olefin copolymer prepared by means of a metallocene catalyst. The film is prepared by coextruding melts corresponding to the indiviaual layers of the film, taking off the coextruded film over a take-off roll whose temperature is between 10 and 90.degree.C, biaxially stretching and then heat-setting the resulting film, and optionally corona- or flame-treating the film, then winding it up in a wind-up unit.
