Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a functionalized substrate in the form of a water-soluble film carrying a coating of a functional composition.SOLUTION: The method includes applying to at least one side of a film an aqueous solution including one or more functional materials to form a coating, where the coating is at least 5 g/m, loading is at least 30 wt.% of a non-coating film, and preferably, the elastic characteristics of the film are measured at 40% relative humidity and at 20°C to be within approximately 40%. The coating is formed from a plurality of layers in a stepwise manner and/or the aqueous solution includes a film insolubilizer agent.

Abstract:
PROBLEM TO BE SOLVED: To provide a water-soluble articles such as films, which is made to have resitance to contact with small amounts of water, and methods of making the same.SOLUTION: The water-soluble article 10 is formed from a water-soluble film-forming composition, such as polyvinyl alcohol, and includes salt 20 that is distributed more closely to at least one of the surfaces than throughout its entire thickness 16.
Abstract:
PROBLEM TO BE SOLVED: To provide a film-forming composition which is soluble only at a pH lower than a specified pH threshold value.SOLUTION: A film-forming composition is produced from a mixture of PVOH, chitosan and an alkali metal or ammonium slat of bisulfite or metabisulfite and an arbitrary constituent ingredient(s), e.g. plasticizers, antioxidants, UV stabilizers, surfactants, crosslinking agents, lubricants and extenders. A method of producing a film from the composition, the film obtained and a packet which is produced with the film and contains a composition for cleaning, e.g. a rinse additive, are also provided.
