Abstract
A composition comprising the following components: a) a first ethylene/alpha-olefin interpolymer that comprises the following properties: i) a melt viscosity (177° C.) from 2,000 to 50,000 mPa·s, ii) a density from 0.855 to 0.885 g/cc; b) a second ethylene/alpha-olefin interpolymer that comprises the following properties: i) a melt viscosity (177° C.) from 2,000 to 50,000 mPa·s, ii) a density from 0.900 to 0.960 g/cc; and wherein the weight ratio of component a to component b is from 1.0 to 100.
