Abstract: This invention relates to inventive ethylene-based copolymers comprising 75.0 wt % to 99.5 wt % of ethylene-derived units and 0.5 wt % to 25.0 wt % of C3 to C20 olefin derived units; the inventive ethylene-based copolymer having: a density in the range of from 0.900 to less than 0.940 g/cm3; a g′(vis) of less than 0.80; a melt index, I2, of from 0.25 to 1.5 g/10 min.; a Mw/Mn within a range from 3.0 to 6.0, and Mz/Mn greater than 8.0; and an absence of a local minimum loss angle at a complex modulus, G*, of 1.00×104 to 3.00×104 Pa.
