Abstract
This disclosure relates to films comprising at least one layer of an ethylene interpolymer product. The ethylene interpolymer product comprises a first ethylene interpolymer, a second ethylene interpolymer and optionally a third ethylene interpolymer; wherein the ethylene interpolymer product has ≥0.03 terminal vinyl unsaturations per 100 carbon atoms and ≥3 parts per million (ppm) of a total catalytic metal; and optionally a Dilution Index, Y, greater than 0. The disclosed ethylene interpolymer products have a melt index from about 0.4 to about 10 dg/minute, a density from about 0.900 to about 0.940 g/cm, a polydispersity (M/M) from about 2 to about 12 and a CDBIfrom about 20% to about 98%. 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.
