Abstract
Fabricated articles made from formulated ethylene polymer compositions are disclosed. Films made from such formulated compositions have surprisingly good impact and tensile properties, and an especially good combination of modulus and toughness. The ethylene polymer compositions have at least one homogeneously branched substantially linear ethylene/.alpha.-olefin interpolymer and at least one heterogeneously branched ethylene polymer. The homogeneously branched substantially linear ethylene/.alpha.-olefin interpolymer has a density from about 0.89 to about 0.92 g/cm.sup.3 and a slope of strain hardening coefficient greater than or equal to about 1.3.
