Abstract

Disclosed herein are sealing solutions for sealing water-soluble films, in particular aqueous mixtures including one or more polymeric solvents such as polyols. Aqueous sealing solutions including a relatively dilute solvent for one or more polymeric components of the water-soluble film (e.g., water-soluble polymeric components thereof, such as polyvinyl alcohol (PVOH)) can exhibit one or more benefits, including a reduction in dissolution of the film by the sealing solution and an increase in seal strength. Also disclosed are sealed articles formed with the sealing solutions, for example water-soluble packets containing various liquid or solid compositions.
