    Abstract: A high-density polyethylene (HDPE) can be adapted for the manufacture of caps and closures. The caps and closures can be used as screw-on caps for carbonated or still drinks. The high-density polyethylene can have a density of at least 940 kg/m3 and of at most 970 kg/m3, and a high load melt index HLMI of at least 35 dg/min and of at most 180 dg/min. The high-density polyethylene can include a first polyethylene fraction and a second polyethylene fraction. The first polyethylene fraction can have a density of at least 920 kg/m3 and of at most 945 kg/m3, and a melt index HL275 of at least 3 dg/min and of at most 12 dg/min. The second polyethylene fraction can have a density of at least 960 kg/m3 and of at most 980 kg/m3.

    Abstract: Heterophasic propylene copolymers can include a matrix phase and a dispersed phase. The heterophasic propylene copolymers can be characterized by good processability and good mechanical properties, particularly an improved rigidity. The heterophasic propylene copolymers can be well-suited for injection molding applications, particularly for injection molding of thin-walled articles.

    Abstract: The present invention relates to a polyethylene resin suitable for preparing moulded articles, such as caps and closures. The invention provides in particular a polyethylene resin comprising at least two polyethylene fractions A and B, wherein said polyethylene resin has a melt index (MI2), of at least 3.0 g/10 min to at most 5.5 g/10 min as measured according to ISO 1133, condition D, at 190° C. and under a load of 2.16 kg, and a density of at least 0.955 g/cm3 to at most 0.965 g/cm3 as measured according to ISO 1183 at 23° C., and a molecular weight distribution Mw/Mn which is at most 7.0, as determined by gel permeation chromatography, with Mw being the weight-average molecular weight and Mn being the number-average molecular weight; and wherein said polyethylene fraction A has a high load melt index (HLMI), as measured according to ISO 1133:1997 condition G at 190° C. and under a load of 21.6 kg, of at least 10.5 and a melt index (MI2) of at least 0.5 g/10 min to at most 1.5 g/10 min as measured according to ISO 1133, condition D, at 190° C. and under a load of 2.16 kg. The invention further relates to a process for preparing said polyethylene resin, to a cap or closure comprising said polyethylene, and to a process for producing such a cap or closure.
