USPTO Abstract
The present invention relates to edible multi-layer films (10) that dissolve in water. In particular, the edible multi-layer films (10) have a first water-soluble film layer (10) and one or more additional water-soluble film layers (200) in at least partial face-to-face engagement with the first film layer (100). The film layers (100,200) include a polymer composition which contains polyethylene oxide alone or in combination with at least one water-soluble polymer. The edible multi-layer films (10) may include pockets defined between the layers that house an active component. Upon addition of water, the multi-layer film dissolves, thereby releasing the active component into the water.
