Abstract: Grease resistant packaging is prepared from a high density polyethylene (HDPE) composition that contains a nucleating agent. Outstanding results are observed when the nucleated HDPE composition is included in an internal layer of a multilayer packaging structure. The use of HDPE that is prepared with a chromium or titanium (especially titanium) containing catalyst is preferred. The packaging may be in the form of a monolayer film, a multilayer film, a sheet or a molded part.

Abstract: Coextruded multilayer blown films are produced comprising: a core layer comprising at least one random polypropylene copolymer; at least one skin or intermediate layer adjacent to said core layer; wherein the coextruded multilayer film has at least about 30% higher machine direction tear, at least about 30% improved tear ratio (machine direction tear divided by transverse direction tear) and at least about 10% lower film haze, relative to a similar multilayer film comprising at least one impact polypropylene copolymer in the core layer.

Abstract: A polymer composition comprises at least an ethylene/?-olefin interpolymer and at least one other polymer. The other polymer can be selected from a second ethylene/?-olefin interpolymer, an elastomer, a polyolefin, a polar polymer, and an ethylene/carboxylic acid interpolymer or ionomer thereof. The ethylene/?-olefin interpolymer is a block copolymer having at least a hard block and at least a soft block. The soft block comprises a higher amount of comonomers than the hard block. The block interpolymer has a number of unique characteristics disclosed here. Also provided are gaskets, bottle cap liners, and closures that comprise or obtained from a compositon comprising at least one ethylene/?-olefin interpolymer and at least one polyolefin. The gaskets are capable of compression sealing various containers, without contaminating the contents. Liquid containers particularly benefit from the use of the novel gasket materials disclosed herein.

Abstract: The present invention includes a coextruded film having at least two layers. The first layer contains a coupled propylene polymer and the second layer contains an in-reactor blend of a linear low density polyethylene fraction and a substantially linear polyethylene fraction. Alternatively, the second layer may include a homogeneously branched linear polyethylene. Preferably, the first layer makes up about 50 weight percent or less of the overall coextruded film structure. The first layer may also contain a polyethylene, such as a linear low density polyethylene, a low density polyethylene, a high density polyethylene, substantially linear polyethylene, a homogeneously branched linear polyethylene, an in-reactor blend of linear low density polyethylene and a substantially linear polyethyelene, and blends thereof.

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.
