Disclosed herein are sealing solutions for sealing water-soluble films, particularly aqueous mixtures comprising one or more polymeric solvents such as polyols. An aqueous encapsulating solution comprising a relatively dilute solvent for one or more polymer components of the water soluble film (e.g., a water soluble polymer component thereof, such as polyvinyl alcohol (PVOH)), may reduce the solubility of the film by the encapsulating solution, May represent one or more of the advantages including increased strength. A water-soluble packet containing a sealed article formed of a sealing solution, for example, various liquid or solid compositions, is also disclosed. |
