    Abstract: A non-sealable, multi-layer polypropylene film which includes a base layer of polypropylene and at least one cover layer. The cover layer includes a propylene-ethylene copolymer which includes about 1.2 to 2.8% by weight of ethylene and has a distribution factor V.sub.F greater than about 10, an enthalpy of fusion .DELTA.H.sub.m greater than about 90 J/g and a melt index of about 3 to 12 g/10 min. under a load of 21.6N and about 230.degree. C. The film is particularly useful in laminating and as a support film for aqueous coating systems.

    Abstract: For packaging purposes, metallized multilayer films containing a biaxially oriented polypropylene film as a base layer should have high scratch resistance, good heat-sealing properties, such as low heat-sealing temperature, attractive visual properties, such as high metallic luster, excellent metallizability of the base layer or of a covering layer, and also good processing properties during metallization, printing, slitting, and during processing on fast-running packaging machines. This requirement profile is fulfilled by a multilayer film of asymmetric structure containing a biaxially oriented base layer 4 composed of polypropylene, a heat-sealing layer 3 which contains an additive combination composed of pigment in platelet form and siloxane and which is optionally modified by an addition of polypropylene and a hydrocarbon resin, and of a corona-treated polypropylene covering layer 2 which is not capable of being heat-sealed. A corona-treated, heat-sealable copolymer may also be used as the covering layer 2, instead of a covering layer 2 composed of non-heat-sealable polypropylene. The covering layer 2 can also be omitted; in that case the surface of the base layer 4 is metallized. Tubular bags, jackets, containers of various shape for packaging foodstuffs, including the vacuum packaging of foodstuffs, are manufactured from this multilayer film.

    Abstract: A packaging wrapper for disk-shaped magnetic information carriers is disclosed. The wrapper is formed by folding over a blank to form a flat wrapper. The wrapper has projecting tabs jutting out laterally from the sides of the front wrapper wall and overlap zones on the rear wrapper wall formed as a result of folding-over of the projecting tabs. The projecting tabs are firmly bonded to the rear wrapper wall by means of welding. The blank for forming the packaging wrapper is formed from a biaxially oriented, opaque multi-ply film comprising a base layer consisting essentially of polypropylene and fillers. The fillers are present in a quantity in the range from 10 to 30% by weight, relative to the total weight of the polypropylene and fillers.

    Abstract: An opaque polyolefin film having a three-layer support film and transparent or clear polyolefin covering layers which cover the two surfaces of the support film. In the support film, either the inner layer or the two intermediate layers arranged between the inner layer and the covering layers are composed of a filler-free polyolefin which is modified with a natural or synthetic resin having a softening point ranging from 70.degree. C. to 180.degree. C. The respective non-modified polyolefin layer or layers of the support film have a filler and exhibit a vacuole structure which produces a relatively low density film of less than 0.9 g/cm.sup.3. The production of the opaque polyolefin film comprising five layers is carried out by coextrusion and biaxial stretching, followed by heat setting the coextruded film. The film is advantageously used for packaging purposes.
