US Patent 9493591 Ethylene based polymers and articles made therefrom

An ethylene-based polymer comprising about 80.0 to 99.0 wt. % of polymer units derived from ethylene and about 1.0 to about 20.0 wt. % of polymer units derived from one or more C3 to C20 α-olefin comonomers; the ethylene-based polymer having: a CDBI of 60% to 80%; a melt index, I2.16, of about 4.0 to about 12.0 g/10 min.; a high-load melt index, I21.6, of 80.0 to about 160.0 g/10 min.; a melt index ratio (I21.6/I2.16) of 9.0 to 40.0; and a density of from about 0.910 to about 0.930 g/cm3. Articles, such as films, particularly suitable for use in pre-stretch applications, produced from such polymers and methods of making such articles are also provided.
