Abstract: Coated multilayer polyethylene films having improved sealability and barrier properties are provided. The films include a substrate which has been oriented in the machine direction to a degree of from about 5:1 to about 8:1 and in the direction transverse to the machine direction to a degree of from about 6:1 to about 15:1, and a coating selected from the group including polyvinylidene chloride, low temperature seal coating, polyvinyl alcohol polymer and acrylic coating. The substrate has a high density polyethylene base layer and at least a first skin layer adhered to a first side of the base layer.

Abstract: A multi-layered film that may be heat laminated to a substrate is described. The multi-layered film comprises a base layer comprising polypropylene, a first external layer comprising polypropylene, and a second external layer. The base layer is interposed between the first and second external layers. The second external layer comprises a mixture of first (i) and second (ii) ethylene vinyl acetate (EVA) copolymers, each having different vinyl acetate residue contents. The content of vinyl acetate residues in the first EVA copolymer (i) is 10 to 30 percent by weight, based on the weight of the first copolymer (i), the content of vinyl acetate residues in the second EVA copolymer (ii) is 1 to 10 percent by weight, based on the weight of the second copolymer (ii). The multi-layered film is heat laminated and oriented at least monoaxially.

Abstract: A multi-layer film including: (a) a substrate layer of a thermoplastic polymer film having opposed first and second surfaces; and (b) a heat sealable layer associated with the first surface of the substrate and including (i) a first acrylic polymer and (ii) a second polymer which is a copolymer including residues derived from one or more olefinically unsaturated monomers and residues derived from one or more olefinically unsaturated monomers which include one or more functional groups. The first polymer (i) has a glass transition temperature in the range of from 40 to 120° C. and a weight average molecular weight in the range of from 20,000 to 60,000, the second polymer (ii) is a copolymer of a C1-C4 olefinically unsaturated hydrocarbon and an olefinically unsaturated carboxylic acid, and the heat-sealable layer includes from 5 to 60% by weight of the first acrylic polymer and from 40 to 95% by weight of the second polymer.

Abstract: An oriented multilayer film is provided, the film including in at least one outer layer an ethylene copolymer having a density of 0.900-0.935 g/cm3 and a CDBI of 50-95% the outer layer is in contact with a polypropylene core layer, and the film is made by coextrusion of the ethylene copolymer and the polypropylene layer and subsequent orientation. The coextruded layers can be uniaxially oriented or biaxially oriented without difficulties caused by presence of low molecular weight amorphous polymer fractions inherently present in traditional Ziegler-Natta linear low density polyethylene. The optical properties of oriented polypropylene films can be retained, while the sealing temperature is lowered and the heat seal strength and the hot tack performance properties are improved.

Abstract: Stretch plastic film is formed by extruding suitable plastic material from an annular die as a tubular film, forming the extruded film into a bubble with air entrapped therein by collapsing the tubular film at a predetermined distance from the annular die, causing the temperature of the tubular film when collapsed to be sufficiently high to cause opposite sides of the collapsed film to become bonded together to form a blocked two layer film, and stretching the blocked two layer film to reduce its thickness.

Abstract: Polyolefin films having high oxygen transmission values are composed of blends of more than about 10% by weight to about 60% by weight of isotactic polypropylene, about 10% by weight to about 25% by weight of low density polyethylene and about 15% by weight to less than about 80% by weight of an olefin heteropolymer containing propylene and at least one other &agr;-olefin of 2 to 4 carbon atoms having a melting point less than that of polypropylene and a density of no greater than about 0.95 g/cc.

Abstract: Disclosed is a polyol/polyisocyanate adhesive system having an isocyanate component and a catalyzed component which form a heat-cured composition when admixed and heated above a threshold temperature. The catalyzed component has a hydroxyl-functional component catalyzed with a catalyst combination of a heat-activatable amine or amine-like catalyst which is activated at temperatures above the threshold temperature, and an activatable complexed metal catalyst comprising the reaction product of tin or bismuth catalysts, or a mixture thereof, and a molar excess of a mercapto compound complexing agent. The catalyst combination is effective to maintain the processibility of the system at ambient temperatures while promoting the rapid cure of the system when heated above the threshold temperature.
