Abstract
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.
