A polyethylene resin comprising from 35 to 49 wt% of a firstnpolyethylene fraction of high molecular weight and from 51 ton65 wt% of a second polyethylene fraction of low molecularnweight, the first polyethylene fraction comprising a linear lowndensity polyethylene having a density of up to 0.930 g/cm 3 , andnan HLMI of less than 0.6 g/10min and the second polyethylenenfraction comprising a high density polyethylene having andensity of at least 0.969 g/cm 3 and an MI 2 of greater than 10ng/10min, and the polyethylene resin, having a density ofngreater than 0.946 g/cm 3 ,an HLMI of from 1 to 100 g/10min , andynamical viscosity η 0.01 , measured at 0.01 radians/second,ngreater than 200,000 Pa.s and a ratio of the dynamicalnviscosities measured at, respectively 0.01 and 1 radians/secondnη 0.01 /η 1 greater than 8. |
