PROCESS TO PRODUCE A COMPOSITION OF POLYETHYLENE COMPRISING RECYCLED POST-CONSUMER RESIN AND CAPS OR CLOSURES MADE FROM THIS COMPOSITION

The disclosure relates to a process to produce a composition of polyethylene comprising post-consumer resin for the production of caps and closures , comprising in the steps of providing from 20 wt.% to 85 wt.% of a component A being one or more polyethylene post-consumer resins having a melt index ranging from 0.8 to 3.0 g/10 min, and a density ranging from 0.940 to 0.965 g/cm3; providing a component B being a polyethylene resin having a melt index (MI2) ranging from 0.2 to 1.2 g/10 min, and a density ranging from 0.935 to 0.955 g/cm3; and a multimodal molecular weight distribution, wherein the component B is selected to have a melt index that is equal or inferior to the melt index (MI2) of the component A and to have a molecular weight distribution Mw/Mn which is at most 14.0 as determined by gel permeation chromatography; and blending the components to form a composition having a melt index ranging from 0.8 to 3.0 g/10 min; wherein the composition has an environmental stress crack resistance of at least 360 hours according to ASTM D1693-15 at 100% Igepal and 50° C. and a weight-average molecular weight Mw of at least 90,000 g/mol.
