Abstract
An injection stretch blow molded article may include a Ziegler-Natta catalyzed polyethylene resin having a multimodal molecular weight distribution and including at least two polyethylene fractions A and B. Fraction A may have a higher molecular weight and a lower density than fraction B. Each fraction may be prepared in different reactors of at least two reactors connected in series. Fraction A may have a melt index HL275 of at least 11 g/10 min and of at most 20 g/10 min, and a density of at least 941 kg/mand of at most 946 kg/m. The polyethylene resin may have a melt index MI2 of at least 1.5 g/10 min and of at most 3.0 g/10 min, and a density of at least 950 kg/mand of at most 965 kg/m.
