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%.
