Claim:
1. An injection stretch blow molded article, comprising a Ziegler-Natta catalyzed polyethylene resin, wherein the polyethylene resin has a multimodal molecular weight distribution and comprises at least two polyethylene fractions comprising fraction A and fraction B, fraction A having a higher molecular weight and a lower density than fraction B, each fraction prepared in different reactors of at least two reactors connected in series, wherein: fraction A has a melt index HL275 of at least 11 g/10 min and of at most 20 g/10 min as determined according to ISO 1133, condition G, at 190° C. and under a load of 21.6 kg except that a die of 2.75 mm was used; and a density of at least 941 kg/m the polyethylene resin has a melt index MI2 of at least 1.5 g/10 min and of at most 3.0 g/10 min as determined according to ISO 1133, condition D, at 190° C. and under a load of 2.16 kg; and a density of at least 950 kg/m
