Abstract
The invention provides a composition comprising a first composition, wherein the first composition comprises a first ethylene-based polymer and a second ethylene-based polymer, and wherein the first composition has a high load melt index (I21) less than 17, a density greater than, or equal to, 0.952 g/cm3, a molecular weight distribution MWD (conv), defined as the ratio of the weight average molecular weight to the number average molecular weight (Mw (conv)/Mn (conv)), greater than, or equal to, 11; and a viscosity ratio, η(0.01 s−1)/η(100 s−1) at 190° C., greater than, or equal to, 60.
