Abstract: Disclosed herein are water-soluble films including a polyvinyl alcohol (PVOH) polymer and a combination of at least three plasticizers. The combination of plasticizers includes dipropylene glycol as a first plasticizer, a sugar alcohol such as sorbitol as a second plasticizer, and a polyol such as glycerin as a third plasticizer. When the PVOH polymer and plasticizers 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 beneficial combinations four) of aged tensile strength, aged melting transition delta elevation, aged adhesion value, and/or resistance to seal peeling, which provide strong film seals that retain their water-solubility characteristics.
