Abstract:
The invention provides a composition comprising a first ethylene-based polymer, formed by a high pressure, free-radical polymerization process, and a second ethylene-based polymer, formed by a high pressure, free-radical polymerization process, such composition comprising the following properties: a) a melt index (I2) from 2.0 to 10 dg/min; b) a density from 0.922 to 0.935 g/cc; and wherein the second ethylene-based polymer is present in an amount from 60 to 95 weight percent, based on the sum of the weight of the first polymer and the second polymer; and wherein the second ethylene-based polymer has a density greater than, or equal to, 0.924 g/cc; and wherein the first ethylene-based polymer has a melt index less than 2.5 dg/min.
