Abstract
A polymer composition comprising an ethylene alpha-olefin copolymer, wherein the polymer composition is characterized as having (a) a density in the range of from greater than about 0.910 g/cc to about 0.930 g/cc, as determined according to ASTM D1505; (b) a melt index in the range of from greater than about 0.5 g/10 min to about 3 g/10 min, as determined by ASTM D1238, Condition 190° C./2.16 kg; (c) a molecular weight distribution of from about 3.4 to about 12, as determined by gel permeation chromatography (GPC); (d) a weight average molecular weight of from greater than about 85 kg/mol to about 160 kg/mol, as determined by gel permeation chromatography (GPC); and (e) a z-average molecular weight of from greater than about 210 kg/mol to about 500 kg/mol, as determined by gel permeation chromatography (GPC).
