Abstract: Heat-sealable, white-opaque, biaxially oriented, multilayer polypropylene film, process for the production thereof, and the use thereof. The invention relates to a heat-sealable, white-opaque, biaxially oriented, multilayer polypropylene film comprising a core layer and at least one interlayer arranged there.

Abstract: A sealable, transparent multilayer film comprised of a base layer, essentially of polypropylene, which is coated on both sides with further polyolefin layer is described. The base layer is coated on both surfaces with a layer of polypropylene which contains, as additives(i) 0.1 to 1% by weight of an inorganic pigment and(ii) 0.2 to 1% by weight of an oxyalkylamine, in each case relative to the total weight of the layer. Both free surfaces of the polypropylene layers are coated with a sealable covering layer which comprises a combination of(a) 68.5 to 89.7% by weight of an olefin resin composition comprising a copolymer or terpolymer of ethylene, propylene, butylene or further .alpha.-olefins having 5 to 10 carbon atoms or mixtures of these,(b) 5 to 15% by weight of a low molecular weight resin compatible with the olefin resin composition,(c) 5 to 15% by weight of a propylene homopolymer and(d) 0.3 to 1.
