摘要: A process for the manufacture of a water soluble film with at least one embedded active material. A formulation for the water soluble film is cast on a liner at a casting head (28). The cast water soluble film is smoothed and then dried with the at least one embedded active material at a drier (30). One or more additional water soluble films may be cast onto the cast water soluble film at subsequent casting heads (33) to produce a multi-layer water soluble film.
