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/mand of at most 970 kg/m, 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/mand of at most 945 kg/m, 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/mand of at most 980 kg/m.
