Rotomolded articles comprising at least one layer comprising a metallocene-catalyzed polyethylene resin

A rotomolded article, comprising at least one layer:

• said at least one layer comprising:
• at least one metallocene-catalyzed polyethylene resin comprising at least two metallocene-catalyzed polyethylene fractions A and B, wherein the at least one metatllocene-catalyzed polyethylene resin has a bimodal molecular weight distribution, wherein each fraction of said at least one metallocene-catalyzed polyethylene resin is prepared in at least two slurry loop reactors connected in series;
• and
• at least one ionomer;
• wherein the at least one metallocene-catalyzed polyethylene resin comprises:
• at least 25% to at most 55% by weight of polyethylene fraction A based on the total weight of the at least one metallocene-catalyzed polyethylene resin, wherein fraction A has a density at least 0.005 g/cm3 higher than the density of the at least one metallocene-catalyzed polyethylene resin;
• and
• wherein the at least one metallocene-catalyzed polyethylene resin has a density of at least 0.930 g/cm3 to at most 0.954 g/cm3 as measured according to ASTM D-1505 at 23° C.;
• a melt index MI2 of at least 1.0 g/10 min to at most 25.0 g/10 min as determined according to ISO 1133, condition D, at 190° C. and under a load of 2.16 kg.
