The novel composition is characterized as having a melt flow ratio, I10/I2, from 8 to 30, a Mw/Mn of greater than 4 as determined by gel permeation chromatography, a melt index, I2, from 0.01 to 1000 grams/10 minutes, preferably greater that 0.1 to 10 grams/10 minutes, and a density less than 0.945 g/cm3. The novel composition exhibits good processibility and improved toughness properties, especially excellent film tear and impact resistance, and is particularly well-suited for use in applications such as high performance trash can liners and heavy duty shipping bags.

Film layers made from such formulated compositions have surprisingly good (for example, low) water vapor transmission rates and are particularly useful for packaging dry goods such as cereal. The polymer compositions preferably have at least one homogeneous ethylene homopolymer and at least one heterogeneously branched ethylene polymer. The homogeneous ethylene homopolymer has a molecular weight much higher than that of the heterogeneously branched ethylene polymer, although the density of each is preferably higher than about 0.95 g/cm3.
