SYSTEMS AND METHODS FOR FORMING DUAL LAYER WATER SOLUBLE PACKETS

摘要

Systems and methods for forming dual layer water soluble packets are described. Layers of film contain several layers of powder to form the packets. The systems and methods form openings in a base layer of the film. A vacuum draws ambient air through the openings, while the layers of powder are deposited onto the base layer of film. The vacuum generally holds the powder in position. The layers of powder are deposited onto the base layer of the film and/or on top of previously deposited layers of powder. By depositing the powder while the vacuum is applying the vacuum through the openings, denser and more compacted layers of the powders are formed.
