Film layers made from polymer blends

摘要

Film layers made from formulated polymer compositions are disclosed. Film layers made from such formulated compositions have suprisingly good heat seal properties, and an especially good reduction in heat seal initiation temperature. The polymer compositions preferably have at least one homogeneously branched ethylene/alpha-olefin interpolymer and at least one heterogeneously branched ethylene polymer. The homogeneously branched ethylene/alpha-olefin interpolymer has a density lower than that of the formulated composition and of the heterogeneously branched ethylene polymer.
