<p>A polyethylene resin comprising from 44 to 55 wt% of a high molecular weight polyethylene fraction, and from 45 to 56 wt% of a low molecular weight polyethylene fraction; the high molecular weight polyethylene fraction comprising a linear low density polyethylene having a density of from 0.913 to 0.923g/cm3, and an HLMI of from 0.02 to 0.2 g/10min; and the low molecular weight polyethylene fraction comprising a high density polyethylene having a density of at least 0.969 g/cm3 and an MI2 of greater than 100 g/10min; wherein the relationship between the density D of the resin in g/cm3 and the weight fraction of the low molecular weight fraction P1 is defined by 0.055P1 + 0.916 < D < 0.034P1 + 0.937.</p> |
