Embodiments disclosed herein include multilayer films having a cling layer, a core layer, and a release layer, wherein the cling layer comprises a propylene interpolymer and the core layer comprises a core layer polyethylene composition.

Multilayer stretch films and methods thereof

A multilayer shrink film comprising at least one core layer positioned between a first skin layer and a second skin layer, wherein the multilayer shrink film comprising an ethylene/alpha-olefin interpolymer composition and a low density polyethylene.

Low temperature multilayer shrink films, and methods of making thereof

Provided is a method for increasing the melt strength and/or low shear viscosity of a polyethylene resin. The method includes: a) providing a polyethylene composition including the reaction product of ethylene and optionally, one or more alpha-olefin comonomers, wherein the polyethylene composition is characterized by the following properties: a density ranging from 0.900 g/cmto 0.970 g/cm, a molecular weight distribution (Mw/Mn) ranging from 2.6 to 3.5, and from 0.10 to 0.27 vinyl groups per 1,000 total carbon atoms; b) providing a masterbatch composition including a free radical generator and a polyethylene resin, wherein the free radical generator has a half-life at 220&#xb0; C. of less than 200 seconds, and a decomposition energy higher than &#x2212;250 kJ/mol, and wherein the polyethylene resin has a density ranging from 0.900 g/cmto 0.970 g/cm, melt index ranging from 0.01 g/10 min to 100 g/10 min; and c) reacting the polyethylene composition with the masterbatch composition to form a modified polyethylene composition.

Modified polyethylene compositions and method for making the same

Embodiments disclosed herein include multilayer cast films having a first outer layer, a core layer, and a second outer layer, wherein the first outer layer comprises (a) a linear low density polyethylene (LLDPE), ultra-low density polyethylene (ULDPE), a first polyethylene composition, or combinations of two or more thereof, and (b) polyisobutylene, and the core layer comprises a core layer polyethylene composition.

A multilayer shrink film comprising a first layer, a second layer, and a third layer, wherein the second layer is positioned between the first layer and the third layer, and wherein the second layer comprises a second polymer blend, the second polymer blend comprising from 0 to 60 wt. %, based on the total polymer weight in the second polymer blend, of a low density polyethylene, and from 40 to 100 wt. %, based on the total polymer weight in the second polymer blend, of an ethylene/&#x3b1;-olefin interpolymer composition having a density in the range of from 0.860 g/cc to 0.910 g/cc, a melt index (I) in a range of from 0.1 to 5 g/10 minutes, a molecular weight distribution (M/M) in the range of from 1.8 to 3.5, and a Comonomer Distribution Constant (CDC) in the range of from 95 to 200.
