Abstract:
This disclosure relates to manufactured articles containing ethylene interpolymers. Specifically, films, containers and lids comprising at least one layer of an ethylene interpolymer product, or a blend containing an ethylene interpolymer product, where the ethylene interpolymer product has: a Dilution Index (Yd) greater than 0; total catalytic metal ≥3.0 ppm; ≥0.03 terminal vinyl unsaturations per 100 carbon atoms, and; optionally a Dimensionless Modulus (Xd) greater than 0. The ethylene interpolymer products have a melt index from about 0.4 to about 100 dg/minute, a density from about 0.950 to about 0.970 g/cm3, a polydispersity (Mw/Mn) from about 2 to about 25 and a CDBI50 from about 55% to about 97%. Further, the ethylene interpolymer products are a blend of at least two ethylene interpolymers; where one ethylene interpolymer is produced with a single-site catalyst formulation and at least one ethylene interpolymer is produced with a heterogeneous catalyst formulation.
