Water soluble film and articles comprising same

A water-soluble unit dose article comprising at least one compartment and optionally a composition housed in the compartment, wherein the unit dose article comprises:

• a water-soluble film, the water soluble film comprising a polyvinyl alcohol resin and a plasticizer, the polyvinyl alcohol resin comprising about 70% to about 100% of a polyvinyl alcohol-co-maleate polymer, based on the total weight of the polyvinyl alcohol resin and the plasticizer comprising triethylene glycol, polyethylene glycol having a molecular weight of about 200 Da, or a combination thereof, wherein
• (a) when the polyvinyl alcohol copolymer comprises less than 100% of the polyvinyl alcohol resin, the balance of the polyvinyl alcohol 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, then the plasticizer comprises sorbitol and glycerol;
• and
• (c) when the polyvinyl alcohol resin comprises a blend of the polyvinyl alcohol copolymer and the polyvinyl alcohol homopolymer and (i) the polyvinyl alcohol copolymer is provided in an amount in a range of about 70% to about 90%, by weight based on the total weight of the polyvinyl alcohol resin and (ii) the film comprises a starch, then the film does not include sorbitol and/or glycerol;
• and
• wherein the film is characterized by an elongation at break of at least about 25% after the film is stored in contact with a bleach for 8 weeks at 38° C. and 50% relative humidity (RH);
• wherein the water-soluble film comprises at least one wall of the compartment.
