1. A polymer composition comprising:
from about 80 to about 99.5 wt % ethylene-derived units; and
from about 0.5 to about 20 wt % of alpha-olefin derived units other than ethylene-derived units;
wherein the polymer composition has a total internal unsaturations (Vy1+Vy2+T1) of from about 0.15 to about 0.40 per 1000 carbon atoms, a melt index MI of from about 0.1 to about 6 g/10 min, a high load melt index HLMI of from about 5.0 to about 40 g/10 min, a density of from about 0.890 to about 0.940 g/ml, a Tw1-Tw2 value of from about −50 to about −23° C., an Mw1/Mw2 value of from about 2.0 to about 3.5, an Mw/Mn of from about 4.5 to about 12, an Mz/Mw of from about 2.5 to about 3.0, an Mz/Mn of from about 15 to about 25, and a g′(vis) greater than 0.90.
