The present invention relates to edible multi-layer films that dissolve in water. In particular, the edible multi-layer films have a first water-soluble film layer and one or more additional water-soluble film layers in at least partial face-to-face engagement with the first film layer. The film layers include a polymer composition which contains polyethylene oxide alone or in combination with at least one water-soluble polymer. The edible multi-layer films 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.
