PROCEDURE FOR MANUFACTURING HIGHLIGHTS POLYETHYLENS COMPOSITION WITH HIGH REVENUE RESPONSIBILITY FOR ENVIRONMENTAL EFFECTS FROM RESPONSIBILITY MATERIALS AND RESPONSIBILITY PRODUCED BY THE COMPOSITION

摘要

A process may include providing a polyethylene post consumer resin, providing a virgin polyethylene resin, and blending the polyethylene post consumer resin with the virgin polyethylene resin to produce a composition. The polyethylene post consumer resin may have an ESCR of at most 10 hours, a density ranging from 0.950 to 0.967 g/cm3, and an HLMI of 40 to 70 g/10 min. The virgin polyethylene resin may include fractions A and B, with fraction A having a higher molecular weight and lower density than fraction B. Fraction A may have an HL275 of at least 0.1 g/10 min and of at most 4 g/10 min, and a density of at least 0.920 g/cm3 and of at most 0.942 g/cm. The virgin polyethylene resin may have an HLMI of 5 to 75 g/10 min, and a density ranging from 0.945 to 0.960 g/cm3.
