ABSTRACT A pouch containing a laundry detergent and formed from a porous fabric includes top and bottom permanent seams and longitudinal side seams formed from a water-soluble adhesive. The water-soluble adhesive is a thermoplastic material such as polyvinylacetate or polyvinylalcohol. The pouch contains a measured amount of detergent and is placed in the laundry wash water where the adhesive dissolves to open the pouch and release the detergent. The pouch is formed by attaching a strip of water soluble adhesive on a first web and passing the first web and a second web through a pair of laminating rollers. A metered quantity of detergent is deposited between the webs as they are fed to the laminating rollers to form pouches filled with the detergent.
