Claim Text:
1. An ethylene polymer having a density of greater than or equal to about 0.954 g/cm 3 , a high load melt index (HLMI) in a range from about 10 to about 45 g/10 min, a ratio of high load melt index to melt index (HLMI/MI) in a range from about 175 to about 600, a slope of a plot of the viscosity (in Pa-sec) versus shear rate (in sec −1 ) of the ethylene polymer at 100 sec −1 in a range from about 0.15 to about 0.30, and an environmental stress crack resistance (ESCR, 10% igepal) of greater than or equal to about 800 hours; wherein: the ethylene polymer comprises a high molecular weight component and a low molecular weight component; the high molecular weight component has a Mw in a range from about 1,000,000 to about 1,500,000 g/mol, and a ratio of Mw/Mn in a range from about 1.8 to about 2.7; and the low molecular weight component has a Mw in a range from about 50,000 to about 80,000 g/mol, and a ratio of Mz/Mw in a range from about 1.6 to about 2.5.
