A polyethylene resin comprising from 35 to 49 wt% of a first polyethylene fraction of high molecular weight and from 51 to 65 wt% of a second polyethylene fraction of low molecular weight, the first polyethylene fraction comprising a linear low density polyethylene having a density of up to 0.930 g/cm<3>, and an HLMI of less than 0.6 g/10min and the second polyethylene fraction comprising a high density polyethylene having a density of at least 0.969 g/cm<3> and an MI2 of greater than 10 g/10min, and the polyethylene resin, having a density of greater than 0.946 g/cm<3> ,an HLMI of from 1 to 100 g/10min , a dynamical viscosity eta 0.01 , measured at 0.01 radians/second, greater than 200,000 Pa.s and a ratio of the dynamical viscosities measured at, respectively 0.01 and 1 radians/second eta 0.01/ eta 1 greater than 8. |
