Film layers made from formulated ethylene polymer compositions are
disclosed. Film layers made from such formulated compositions have
surprisingly good heat seal properties, and an especially good reduction
in heat seal initiation temperature. The ethylene polymer compositions
have at least one homogeneously branched ethylene/alpha-olefin
interpolymer and at least one homogeneously or heterogeneously branched
ethylene polymer which has a lower melt index than the first mentioned
component. The first homogeneously branched ethylene/alpha-olefin
interpolymer has a melt index higher than that of the formulated
composition.
