Abstract
The present invention relates to an injection-molded article, comprising at least one metallocene-catalyzed polyethylene resin comprising at least two metallocene-catalyzed polyethylene fractions A and B, wherein the at least one metallocene-catalyzed polyethylene resin comprises: at least 40% to at most 50% 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 melt index MI2 of at least 100.0 g/10 min as determined according to ISO 1133, condition D, at 190° C. and under a load of 2.16 kg; andwherein the at least one metallocene-catalyzed polyethylene resin has a density of at least 0.940 g/cmto at most 0.950 g/cmas measured on pellets according to ISO 1183 at 23° C.; a melt index MI2 of at least 1.4 g/10 min to at most 2.5 g/10 min as measured on pellets according to ISO 1133, condition D, at 190° C. and under a load of 2.16 kg. The present invention also relates to a process for preparing said injection-molded article, comprising the steps of a) providing at least one metallocene-catalyzed polyethylene resin as described herein; and b) injection-molding said polyethylene resin into an article.
