Definitions

  • the present invention relates to water-soluble, liquid-containing pouches, especially to pouches containing cleaning liquids such as detergents and hard surface cleaners. More specifically, the invention is directed to water-soluble pouches which exhibit improved compatibility when used in combination with selected levels of water and ionic components selected from the group consisting of carboxylates, phosphonates, and mixtures thereof.
  • Liquid-filled pouches are known as a convenient form of packaging consumer products as well as industrial products.
  • the liquid can be provided in pre-measured quantities intended for use as "unit doses".
  • the film enveloping the liquid product, which forms the wall of the pouch, is soluble in water.
  • a particularly suitable water-soluble film for this purpose is made from polyvinyl alcohol, and, in this context, this invention is particularly suited to packaging unit doses of liquid detergent.
  • Commonly known water-soluble pouches are generally formed by using either a vertical form-fill-seal (VFFS) or horizontal form-fill-seal (HFFS) processes or by directly thermoforming water soluble envelopes.
  • VFFS vertical form-fill-seal
  • HFFS horizontal form-fill-seal
  • Liquid products have been packaged in water-soluble films wherein the film is made from a water-soluble co-polymer comprising vinyl alcohol and carboxylic acid groups.
  • most of such water-soluble films exhibit poor compatibility when used in combination with compositions packed therein and comprising dissolved ionic components selected from the group consisting of carboxylates, phosphonates, and mixtures thereof.
  • Such ionic components are desirable in liquid detergents as they generally act as builders or chelants.
  • the aforementioned incompatibility translates into a substantial solubility loss of water-soluble pouches made from a film comprising a co-polymer of vinyl alcohol and a carboxylic acid.
