Abstract: A multi-layer heat film having at least three layers is disclosed wherein the film has high optical properties, high stiffness and desirable shrinkage in the cross direction. The inner layer, or layers, comprises at least one stiffening polymer selected from the group consisting of: low density polyethylene, linear low density polyethylene, high density polyethylene, blends thereof, polypropylene random copolymer, styrene/butadiene copolymer, polystyrene/butadiene copolymer, polystyrene, ethylene-vinyl acetate copolymer and cyclic-olefin copolymer, provided that when more than one inner layer is present, the inner layers can be the same or different.

Abstract: The invention provides a film comprising at least one layer, wherein the at least one layer comprises a surface area, and wherein the surface area comprises a plurality of stretched segments, and where each stretched segment is, independently, at least one inch in length, and where the at least one layer is formed from a composition comprising one or more polyolefins, and where the combined weight of the one or more polyolefins is greater than 90 weight percent, based on the total weight of the composition. The invention also provides articles, each comprising at least one component formed from an inventive film, and for methods of preparing such films and articles.

Abstract: The invention relates to perforated films comprising at least one layer, and to packages prepared from the same. Such packages contain a combination of perforation sizes and perforation densities that allows for effective air removal, during a filling, conveying, and palletizing process, and especially during the pressurized filling of fine powder substances. In particular, the invention provides a perforated film, comprising at least one layer, and wherein the at least one layer comprises perforations that are individually of a size less than, or equal to, 100 microns (?m), and wherein the ratio of the total perforation area to the total film surface area is from 400,000 to 2,000,000 square micron per square inch of film (?m2)/(in)2.

Abstract: The present invention pertains to a multilayer blown film structure having a blended polypropylene layer and at least one polyethylene sealant layer. In particular, the invention relates to a multilayer blown film comprising a non-sealant layer made from a propylene-rich polypropylene polymer blended with at least one ethylene-rich ethylene interpolymer and a sealant layer made from at least one ethylene interpolymer, wherein the ethylene-rich ethylene interpolymer comprises ethylene interpolymerized with at least one other comonomer other than propylene. The novel multilayer film structure exhibits excellent interlayer adhesion (especially at the blended non-sealant/sealant interface when adjacent to one another) and toughness (e.g. excellent trouser tear) with acceptable optical properties and surprising sealing properties.

Abstract: An environmentally friendly polymer film pouch made from a polyethylene film structure for the packaging of flowable materials, for example milk, including, for example, a pouch made from a monolayer or multilayer film structure such as a two-layer or a three-layer coextruded film containing at least one layer of a blend of a substantially linear ethylene polymer or a homogeneously branched ethylene polymer and a high pressure low density polyethylene as a seal layer. Also disclosed is a process for making the pouch for packaging flowable materials using a film structure described hereinabove.

Abstract: This invention relates to compositions comprising ethylene interplymers, such as a linear or substantially linear ethylene interpolymer and polydimethylsiloxane. The compositions have good abrasion resistance without sacrificing coefficient of friction.
