The present invention relates to a polyethylene resin prepared using a continuous process having and at least one metallocene catalyst composition: The present invention also relates to articles comprising said polyethylene resin as well as process for preparing said resin.

Polyethylene resins

A metallocene-catalyzed polyethylene resin having a multimodal molecular weight and composition distribution, comprising from 45% by weight to 75% by weight of a low density fraction, said fraction having a density below or equal to 918 g/cmas measured following the method of standard test ISO 1183 at a temperature of 23&#xb0; C., wherein the density of the polyethylene resin is from 0.920 to 0.945 g/cm, wherein the M/Mof the polyethylene is of from 2.8 to 6, wherein the melt index MI2 of the polyethylene resin of from 0.1 to 5 g/10 min measured following the method of standard test ISO 1133 Condition D at a temperature of 190&#xb0; C. and under a load of 2.16 kg; and wherein the composition distribution breadth index (CDBI) of the polyethylene resin is below 70%, as analyzed by quench TREF (temperature rising elution fractionation) analysis.
