Claim 0:
1. An ethylene polymer having:
a density in a range from about 0.952 to about 0.968 g/cm3;
a HLMI in a range from about 10 to about 55 g/10 min, and a ratio of HLMI/MI in a range from about 185 to about 550;
a Mw in a range from about 200,000 to about 450,000 g/mol;
an IB parameter in a range from about 1.46 to about 1.80;
an IVc in a range from about 2.2 to about 3.2 dL/g;
a tan δ at 0.1 sec−1 in a range from about 1.05 to about 1.75 degrees; and
a slope of a plot of viscosity (Pa-sec) versus shear rate (sec−1) of the ethylene polymer at 100 sec−1 in a range from about 0.18 to about 0.28; and
wherein the ethylene polymer comprises an ethylene homopolymer, an ethylene/1-butene copolymer, an ethylene/1-hexene copolymer, an ethylene/1-octene copolymer, or any combination thereof.
