This disclosure relates to multilayer films having improved caulkability. These multilayer films have at least one layer containing an ethylene interpolymer product, or a blend containing an ethylene interpolymer product, where the ethylene interpolymer product has: a Dilution Index (Y) greater than 0; total catalytic metal &#x2265;3.0 ppm; &#x2265;0.03 terminal vinyl unsaturations per 100 carbon atoms, and; optionally a Dimensionless Modulus (X) 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/cm, a polydispersity (M/M) from about 2 to about 25 and a CDBIfrom 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.
