Abstract
A method of automatically manufacturing a filled packette having a closure where a film is advanced from a feed roller to a punch that produces a series of holes in the film. Individual closures are then positioned into each punched hole and ultrasonically welded into place. The film is folded and oriented vertically so that heat sealing may be used to form the side and bottom edges of individual pockets. The film is then clipped to form individual pockets and filed with the appropriate amount of desired material from a bulk feeder. The filled pockets may be sealed along the top edge to form a closed packette and die cut to form the final packette shape.
