IMPROVEMENTS TO CONTINUOUS MOTION ROTATING THERMOFORMING OF SOLUBLE POUCHES

摘要

Soluble pouches are formed on a continous motion rotating thermoforming machine having cavities 11 in the surface of a drum 10 into which a web of polymeric film is drawn by a vacuum to form pockets. The pockets are filled with one or more components and closed by a further web of polymeric film. Shrink-back of the polymeric film within the cavities is reduced by heating the cavities 11 with heaters 125.
