ABSTRACT:
A process for the production of water-soluble pouches. The process comprises the steps of drawing a first film into a mould to form a first compartment, adding composition to the first compartment, drawing a second film into the mould to form a second compartment which comprises a composition and, preferably, sealing. The first film is perforated and the second film is drawn into the mould by means of suction applied through the first film. This eliminates the need to align separately formed pouches or containers. This also reduces the total amount of film needed to produce a multi-compartment pouch. Furthermore, it is very easy to vary the film material used according to what properties are desired. Since the different compartments may require different properties this adds flexibility to the process.Process particularly suited for the production of water soluble pouches such as cleaning or fabric care pouches.
