ETHYLENE-BASED POLYMER COMPOSITIONS FOR IMPROVED EXTRUSION COATINGS
First Claim
1. A composition comprising at least the following:
- a) a first composition comprising at least one first ethylene-based polymer, formed by high pressure, free-radical polymerization, and wherein the first composition comprises the following properties;
a melt index (I2) from 1.0 to 15.0 g/10 min, and density from 0.910 to 0.940 g/cc;
b) a second composition comprising at least one second ethylene-based polymer, and wherein the second composition comprises the following properties;
a melt index (2) from 1.0 to 1000 g/10 min, a density greater than 0.940 g/cc;
wherein the composition comprises the following properties;
melt index (2) from 2.0 to 20.0 g/10 min, and a density from 0.915 to 0.940 g/cc; and
wherein the first composition is present in an amount from 65 to 95 wt %, based on the weight of the composition.
