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.

Abstract: A film-forming composition made from a mixture of PVOH, chitosan, an alkali metal or ammonium bisulfite or metabi sulfite, and optional ingredients such as plasticizers, antioxidants, UV stabilizers, surfactants, crosslinking agents, lubricants, and extenders, is disclosed. Also disclosed are a method of making a film from the composition, a resulting film, and a packet made from the film and containing a cleaning composition such as a rinse additive. The composition can be formulated to yield an article such as a film which is soluble only below a predetermined pH threshold.

Abstract: Generally speaking, the present invention is a water-soluble copolymer film comprising a hydrolyzed copolymer of vinyl acetate and a second monomer, the resultant polyvinyl alcohol copolymer having a degree of hydrolysis, expressed as a percentage of vinyl acetate units converted to vinyl alcohol units, of from about 90% to 100%. The second monomer is preferably selected from the group of monomers having carboxylate functionality or sulfonate functionality. The resulting water-soluble copolymer film is disclosed for use in making pouches to contain a unit dose of liquid detergent, such as a liquid laundry detergent. However, it is an aspect of the copolymer film that film solubility is not significantly affected adversely by the detergent. Such film produces pouches having a greater storage shelf-life over prior art water-soluble film.

Abstract: Methods of treating fibers comprising a polymer including at least one of a vinyl acetate moiety or a vinyl alcohol moiety, and resulting fibers or the products comprising the resulting fibers are disclosed. In an example embodiment, a fiber having a surface region and an interior region, includes a polymer comprising at least one of a vinyl acetate moiety or a vinyl alcohol moiety chemically modified with a modification agent. The fiber has a transverse cross-section including the interior region comprising the polymer having a first degree of modification and the surface region comprising the polymer having a second degree of modification greater than the first degree of modification.

Abstract: A water-soluble film for packaging oxidizing agents including a polyvinyl alcohol resin and a plasticizer, the polyvinyl alcohol resin comprising about 70% to about 100% of a polyvinyl alcohol copolymer including a maleate unit, wherein (a) when the polyvinyl alcohol copolymer comprises less than 100% of the polyvinyl alcohol resin, the balance of the resin comprises a polyvinyl alcohol homopolymer; (b) when the polyvinyl alcohol copolymer comprises 100% of the polyvinyl alcohol resin and the film comprises a starch, the plasticizer comprises sorbitol and glycerol; and (c) when the polyvinyl alcohol resin comprises a blend of polyvinyl alcohol polymers and the polyvinyl alcohol copolymer is provided in an amount in a range of about 70% to about 90%, by weight, and the film comprises starch, then the film does not include sorbitol and/or glycerol; and the film is characterized by an elongation at break of at least about 25%.
