Abstract: Disclosed herein are water-soluble films including a polyvinyl alcohol (PVOH) resin blend and optionally one or more additional components such as plasticizers, fillers, surfactants, and other additives. The PVOH resin blend includes a first copolymer including a first anionic monomer unit and a second PVOH copolymer including a second anionic monomer unit. When the PVOH copolymers are blended in particular proportions and/or selected with regard to various criteria related to physical and chemical film properties, the resulting water-soluble film formed from the PVOH resin blend exhibits maintained film stiffness, and pouch tautness when in contact with liquid pouch contents, and/or maintain acceptable clarity properties, without impairing the ultimate solubility of the water-soluble film.
