Abstract

The specification describes a sealant film composition comprising at least two ethylene polymer components. The sealant film composition comprises: from 5 to 95 weight percent, based on the total weight of the composition, of at least one first ethylene polymer which is a homogeneously branched substantially linear ethylene polymer or a homogeneously branched linear ethylene polymer. The first ethylene polymer is characterized as having: i. Melt flow ratio, I10/I2, of greater than 5.63, ii. an I2 melt index in the range of from 0.001g/10 minutes to 2 g/10 minutes, as measured by ASTM D-1238 Condition 190 C/2.16 kg, iii. a density in the range of from 0.85 to 0.92g/cc, as measured in accordance with ASTM D 792, iv. a molecular weight distribution, MW/Mn as determined by gel permeation chromatography of less than 3.5, v. a short chain branching distribution index (SCBDI) greater than 50 percent, as determined using temperature rising elutionfractionation, and from 5 to 95 weight percent, based on the total weight of the composition, of at least one second ethylene polymer which is a homogeneously branched ethylene polymer or a heterogeneously branched linear ethylene polymer. The second ethylene polymer is characterized as having a density less than 0.97 g/cc. The composition is characterized as having a composition density of from 0.89 g/cc to 0.95 g/cc, as measured in accordance with ASTM D-792, and the I2 melt index of the at least one first polymer is lower than the I2 melt index of the at least one second polymer.
