Claim Text:
1. A polyethylene composition comprising: 1) a density from 0.952 to 0.960 g/cm 2) a MIF/MIP ratio from 17 to 30, wherein MIF is the melt flow index at 190° C. with a load of 21.60 kg, and MIP is the melt flow index at 190° C. with a load of 5 kg, both determined according to ISO 1133; and 3) a SIC Index from 2.5 to 5.0; where t onset,SIC @1000 is measured in seconds and is the time required for crystallization onset under shear rate of 1000 s −1 , the t onset, quiescent is measured in seconds and is the crystallization onset time at temperature of 125° C. under no shear, determined in isothermal mode by differential scanning calorimetry; HLMI is the melt flow index determined at 190° C. with a load of 21.6 kg, according to ISO 1133.
