A composition comprising an ethylene-based polymer which comprises the following properties: a) MWD(conv) from 3.0 to 7.0; b) an ADF IR between 0.230 and 0.260 for molecular weight &#x2264;15,000 g/mol c) 12 from 4.0 to 6.5 g/10 min.

Ethylene-based polymers with good processability for use in multilayer films

Disclosed herein is a cast film comprising a polyethylene composition comprising the reaction product of ethylene and optionally one or more alpha-olefin comonomers, wherein said polyethylene composition is characterized by the following properties: a melt index, I2, measured according to ASTM D1238 (2.16 kg, 190&#xb0; C.), of from 1 to 20 g/10 min; a density (measured according to ASTM D792) of from 0.935 to 0.970 g/cm3; a melt flow ratio, I/I, wherein Iis measured according to ASTM D1238 (10 kg, 190&#xb0; C.) of from 5.5 to 7.0; a molecular weight distribution (Mw/Mn) of from 2.2 to 3.5; and a vinyl unsaturation of greater than 0.12 vinyls per one thousand carbon atoms present in the backbone of the composition.

Cast films, and articles made therefrom

The present disclosure is directed to compositions and film structures suitable for heat seal production. The heat sealable flexible film structure includes: a layer (A) comprising a blend comprising from 35 to 80 percent by weight of the layer (A) of a propylene based plastomer or elastomer ('PBPE') and from 20 to 65 percent by weight of the layer (A) of a low density polyethylene having a density in the range of from 0.915 g/cmto 0.935 g/cm, wherein the blend has a melt index (as determined according to ASTM D 1238 (at 190&#xb0; C./2.16 Kg); a layer (B), adjacent to layer (A), comprising a polyolefin-based polymer, wherein the polymer or polymer blend which makes up layer (B) flows more easily than the blend of layer (A) under conditions intended for making a hard seal with the film structure; and an outermost layer (C) comprising a material having a melting point greater than 140&#xb0; C.; wherein the ratio of the thickness of layer (B) to the thickness of layer (A) is 3:1 or greater. The heat sealable flexible film structure is used to make a flexible container having one or more heat seals. The heat seal can be a frangible heat seal, a hard heat seal, or a combination of frangible heat seals and hard heat seals depending on the sealing conditions.
