A water-soluble film, comprising a first water-soluble film, wherein the first water soluble film disintegrates in water within less than about 24 hours and dissolves in water within less than about 48 hours as measured by the MSTM-205 at 20° C. The disclosure provides a water-soluble film comprising a first water-soluble film that disintegrates in water within less than 24 hours and dissolves in water within less than 48 hours as measured by MSTM-205 at 20° C. The first water-soluble film optionally may be further characterized in that it does not disintegrate in water for at least about 1 hour and does not dissolve in water for at least about 1 hour as measured by MSTM-205 at 20° C. The disclosure further provides a water-soluble film comprising a first water-soluble film characterized in that the degradation and/or dissolution of the first water-soluble film is adapted to be activated by consumer handling.

The first water-soluble film optionally may be further characterized in that it does not disintegrate in water for at least about 1 hour and does not dissolve in water for at least about 1 hour as measured by MSTM-205 at 20&#xb0; C.

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.

Polyvinyl alcohol copolymer film for packaging liquid products and having an improved shelf-life

Water-soluble copolymer film packet

A water-soluble film for packaging a non-liquid product, a package employing the film, and methods of making the same, are disclosed. The film is made from a hydrolyzed copolymer of vinyl acetate and methyl acrylate in a range of from about 30 to about 95 percent by weight, modified starch in a range of from about 4 to about 30 percent by weight, plasticizer in a range of from about 5 to about 30 percent by weight, lubricant/release agent in a range of from about 0.0 to about 1.5 percent by weight, and surfactant in a range of from about 0.01 to about 1.5 percent by weight.

Starch-loaded polyvinyl alcohol copolymer film for packaging non-liquid product and method for making the same

A water-soluble film for packaging a non-liquid product is disclosed. The film is made from a hydrolyzed copolymer of vinyl acetate and methyl acrylate in the range of from about 30 to about 95 percent by weight, modified starch in the range of from about 8 to about 30 percent by weight, plasticizer in the range of from about 5 to about 30 percent by weight, lubricant/release agent in the range of from about 0.0 to about 1.5 percent by weight, and surfactant in the range of from about 0.01 to about 1.5 percent by weight. The increased starch content of the resultant film lowers production cost, but creates physical incompatibilities for use with liquid products.

Starch-loaded polyvinyl alcohol copolymer film

A multi-layer film includes a structural layer of water-soluble film, and a barrier layer. The barrier layer is affixed to spaced apart discrete areas of the structural layer. The barrier layer has insufficient structural integrity and strength to contain a bag's contents once the structural layer has been dissolved. A bag is formed by overlapping areas of the multi-layer film which do not include the barrier layer, and sealing the overlapping areas to one another.
