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 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.

Abstract: A sealable, transparent polyolefinic multilayer film composed of a polypropylene base layer, a non-sealable surface layer, and a sealable surface layer, and process therefor. The sealable surface layer has a low minimum sealing temperature and is made from a copolymer of propylene and ethylene or butene-1 units and/or a terpolymer of ethylene, propylene and butene-1 units. The non-sealable layer is a combination of a propylene homopolymer, a slip agent, and an anti-blocking agent. The process includes coextruding the three layers, biaxially stretching the coextruded film, and subjecting the non-sealable layer to a corona-discharge treatment.

Abstract: A coextruded multi-layer opaque film which has been biaxially oriented by stretching in the longitudinal direction and transverse direction at selected temperatures and with selected stretch ratios, and a method for producing the film. The film has a base layer of polypropylene or a copolymer thereof, and fillers. Its density is 0.4 to 0.6 g/cm.sup.3, the amount of filler, based on the mixture of polypropylene and filler, is 16 to 30% by weight, and the particles of the filler employed have a mean size of 2 to 5 .mu.m. Because of its reduced tendency to recover after folding, the film is particularly suitable for packaging purposes. One or more surface layers can be applied on either or both sides of the base layer.

Abstract: A sealable, opaque polyolefinic multilayer film composed of a polypropylene base layer, a non-sealable surface layer, and a sealable surface layer, and process therefor. The sealable surface layer has a low minimum sealing temperature and is made from a copolymer of propylene and ethylene or butene-1 units and/or a terpolymer of ethylene, propylene and butene-1 units. The non-sealable layer is a combination of a propylene homopolymer and a slip agent. The base layer contains an additive which is incompatible with polypropylene. The process includes stretching of the film, and during the stretching step, the polymer matrix is torn open around the additive particles to form vacuoles which give the base layer a degree of opacity.
