Extruded, copolymer pellet compositions and methods for making the same. A copolymer pellet composition can have an ethylene content of about 40 wt % to about 50 wt % and a propylene content of about 50 wt % to about 60 wt %, based on total weight of the copolymer, wherein the copolymer has a MFR (230° C./2.16 kg) of from about 3.0 g/10 min and about 25 g/10 min; a MWD (Mw/Mn) of about 2.3 or less; and no measurable melting peak, as measured by DSC.
