Abstract:
Water-soluble articles such as films, which can be made resistant to contact with small amounts of water, and methods of making the same are disclosed. The water-soluble article is formed from a water-soluble film-forming composition, such as polyvinyl alcohol, and includes a salt that is distributed more closely to at least one of the surfaces than throughout its thickness.
