摘要： 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.

摘要： 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.

摘要： 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.

摘要： A biaxially stretch-oriented film, suitable for the process of transfer metallizing, which comprises a base layer coextruded with covering layers on either side thereof and comprising an inert admixture is disclosed. The three layers are formed of polyolefin and the base layer comprises an additive which migrates from the base layer into the covering layers. The base layer contains the inert admixture in the form of finely divided particles, which partially protrude from the base layer and are completely enveloped by the covering layers. At least one of the two outer surfaces of the covering layers displays, at least in partial areas, an increased roughness attributable to the particles protruding from the base layer.

摘要： A molten film extruded from a slot die onto a take-off drum in a cooling system is first cooled on the circumferential surface of the take-off drum and by the ambient air, is subsequently passed into the water bath of a water trough in which the take-off drum is immersed, and finally is transferred from the water bath of the water trough into a post-cooling water bath, in which the film solidifies to an intermediate film having a desired final temperature of approximately 40.degree. C. When the film leaves the take-off drum, the partially solidified molten film has a mean temperature T.sub.u of between 100.degree. C. and 120.degree. C. For optimization of the dwell time of the molten film in the cooling system and in the post-cooling water bath, the drum diameter D of the take-off drum and the length L of the post-cooling water bath are determined by a specific relationship.

摘要： A transfer-metallization method in which a metal coating is applied to a top layer of a metallizing film, and the film is then brought into contact with a substrate such that the metal coating is transferred from the top layer to the substrate. The film is a three-layer biaxially-oriented transfer film produced by coextrusion and having a base layer of a polypropylene homopolymer and top layers applied to the two surfaces thereof. The base layer contains an additive depot of migrating monomers in an amount of 0.01 to 2.0 percent by weight, relative to the weight of the polymer constituting the base layer. The top layers are comprised of polypropylene that has a lower viscosity than the polypropylene of the base layer.

摘要： In the process for the production of thin, biaxially stretched films from polypropylene, the latter is melted in an extruder and extruded from a slot die over the surface of a take-off roll. The plastic melt cooled on the surface of the take-off roll into an intermediate film is temperature-treated in the region of the take-off roll in a zone and the intermediate film is subsequently biaxially stretched and heat-set in a known way. At a take-off roll temperature T.sub.W of between 10.degree. C. and 100.degree. C., blowing air of a temperature T.sub.L greater than/equal to 30.degree. C. is blown onto the film surface on the air side not in contact with the circumferential surface of the take-off roll, the duration for this temperature treatment being at least 1.5 seconds.
