Abstract
Provided in this disclosure is an ethylene interpolymer composition. The ethylene interpolymer composition includes a first ethylene interpolymer, a second ethylene interpolymer, and a third ethylene interpolymer. Further, the ethylene interpolymer composition has a density of at least 0.945 g/cm3; an environmental stress crack resistance (ESCR), measured according to ASTM D1693, Condition B, 10% IGEPAL CO-360, of at least 90 hours; and an Izod impact strength of at least 80 J/m, as measured according to ASTM D256.
