摘要： Embodiments of the present invention relate to polyethylene-based compositions, monolayer films, multilayer films, laminates, and articles. In one aspect, a polyethylene-based composition comprises (A) at least 95% by weight, based on the total weight of the polyethylene-based composition, of one or more polyethylenes; and (B) 250 to 15,000 ppm, based on the total weight of the polyethylene-based composition, of a polydimethylsiloxane having a number average molecular weight (Mn) of 1,000 to 40,000 g/mol, wherein the polyethylene-based composition has a density of 0.865 to 0.915 g/cm3 and a melt index (I2) of 0.5 to 25 g/10 minutes.

摘要： The present invention provides multilayer films and packages formed from such films. In one aspect, a multilayer film comprises Layer A which is a sealant layer having a top facial surface and a bottom facial surface and comprising at least 30 weight percent low density polyethylene based on the weight of Layer A; and Layer B having a top facial surface and a bottom facial surface and comprises at least 70 weight percent of at least one of homopolymer polypropylene, random copolymer polypropylene, an impact copolymer of polypropylene, or a combination thereof based on the weight of Layer B, wherein the top facial surface of Layer B is in adhering contact with a bottom facial surface of Layer A, wherein the film is configured to provide a peelable seal that opens due to delamination between Layer A and Layer B.

摘要： The present invention provides multilayer films and packages formed from such films. In one aspect, a multilayer film comprises an outer layer, the outer layer comprising a polyethylene having a density of 0.930 g/cm3 or greater and 0.01 to 1 weight percent of an additive, based on the total weight of the polyethylene composition, the additive comprising either a sorbitol acetal derivative or a bisamide as specified, wherein the outer layer has a 50% seal strength temperature at least 10° C. greater than an outer layer in a comparative film that differs only in the absence of the additive in the outer layer, when sealed to itself at a pressure of 5 bar with a dwell time of 0.5 seconds.

摘要： The present invention provides multilayer films and packages formed from such films. In one aspect, a multilayer film comprises Layer A which is a sealant layer having a top facial surface and a bottom facial surface, wherein Layer A comprises (a) a copolymer comprising ethylene and alkylacrylate, wherein the copolymer has a melt index (I2) of 2 to 30 g/10 minutes and wherein the total amount of alkylacrylate in the copolymer is 5 to 30 weight percent based on the weight of the copolymer, and (b) a polyolefin elastomer having a crystallinity of 30% or less and a melt index (I2) of 1.0 g/10 minutes or more; and Layer B having a top facial surface and a bottom facial surface, wherein the top facial surface of Layer B is in adhering contact with a bottom facial surface of Layer A.
