Abstract
An aqueous barrier coat for formable cellulosic substrates comprises a blend of A) at least one aqueous polymer binder dispersion at 40 wt % to 95 wt %, B) at least one active filler at 3 wt % to 30 wt % and, C) one or more optional additives, such as wetting additives, dispersants, thickeners, defoamers, and crosslinkers. Crystallinity is present in at least one of the polymer binder dispersion and active filler particle. The resulting dried film has a shear storage modulus between 50° C. and 60° C. in the range of 1.5×10to 1×10Pascals, a shear storage modulus between 80° C. and 90° C. in the range of 2×10to 5×10Pascals, and a shear storage modulus between 100° C. and 110° C. is in the range of 5×10to 1×10Pascals. The total weight % of crystalline polymer binder and the crystalline active filler combined is greater than 50%.
