A film includes 20.0 weight percent to 69.5 weight percent of a linear low density polyethylene (LLDPE) based polymer. The LLDPE having a high density fraction (HDF) from 3.0% to 8.0%, an I/Iratio from 5.5 to 6.9, and a short chain branching distribution (SCBD) of less than or equal to 8.0° C. The film also includes 0.0 weight percent to 10.0 weight percent low density polyethylene (LDPE) based polymer, and 30.0 weight percent to 70.0 weight percent pore former.

Polymer-based film with balanced properties

The present disclosure provides a multilayer film. The multilayer film includes at least two layers including a sealant layer and a second layer in contact with the sealant layer. The sealant layer contains (A) a first ethylene-based polymer having a density from 0.895 g/cc to 0.925 g/cc and a melt index from 0.5 g/10 min to 30 g/10 min; (B) a branched fatty acid amide; and (C) a linear saturated fatty acid amide, wherein the branched fatty acid amide and the linear saturated fatty acid amide have a weight ratio of from 1:5 to 3:1. The second layer contains a second ethylene-based polymer.

Multilayer films and laminates containing slip agents

A cast film inducing a bimodal ethylene-based polymer having a high density fraction (HDF) from 3.0% to 10.0%, an I/Iratio from 5.5 to 7.0, a short chain branching distribution (SCBD) less than or equal to 10° C., a density from 0.910 g/cc to 0.920 g/cc, and a melt index (I) from 1.0 g/10 mins to 8.0 g/10 mins.

Cast films comprising bimodal ethylene-based polymers having high molecular weight high density fractions

A bimodal ethylene-based polymer, including a high density fraction (HDF) from 3.0% to 25.0%, wherein the high density fraction is measured by crystallization elution fractionation (CEF) integration at temperatures from 93° C. to 119° C., an I/Iratio from 5.5 to 7.5, wherein Iis the melt index when measured according to ASTM D 1238 at a load of 2.16 kg and temperature of 190° C. and Iis the melt index when measured according to ASTM D 1238 at a load of 10 kg and temperature of 190° C., and a short chain branching distribution (SCBD) less than or equal to 10° C., wherein the short chain branching distribution is measured by CEF full width at half height.

Bimodal ethylene-based polymers having high molecular weight high density fractions

A blown film having a bimodal ethylene-based polymer including a high density fraction (HDF) from 3.0% to 25.0%, an I/Iratio from 5.5 to 7.5, a short chain branching distribution (SCBD) less than or equal to 10 C, a zero shear viscosity ratio from 1.0 to 2.5, a density from 0.902 g/cc to 0.925 g/cc, and a melt index (I) from 0.5 g/10 mins to 2.0 g/10 mins.

Blown films comprising bimodal ethylene-based polymers having high molecular weight high density fractions

A method of producing bimodal ethylene-based polymer includes reacting ethylene monomer and C-C&#x3b1;-olefin comonomer in the presence of a first catalyst in an agitated reactor to produce a first polymer fraction, and outputting effluent from the agitated reactor. A second catalyst is added to the effluent downstream of the agitated reactor and upstream from a non-agitated reactor, the second catalyst facilitates production of a second polymer fraction having a density and melt index (I) different from the first polymer fraction. The second catalyst and effluent are mixed in at least one mixer. The second catalyst, second polymer fraction, and the first polymer fraction are passed to the non-agitated reactor; and additional ethylene monomer, additional C-C&#x3b1;-olefin comonomer, and solvent are passed to the non-agitated reactor to produce more second polymer fraction and thereby the bimodal ethylene-based polymer.
