Project Description
Precise, contactless sealing of soluble pouches.
To produce the capsules, the PVOH film is first deep-drawn into a prefabricated mould and the resulting chambers are then filled with powder, gel or liquid. To ensure secure sealing of the products, Harro Höfliger uses a special head that applies water to the lidding film in a precise and controlled manner: individually metered water droplets solubilise the lidding film before it is placed onto the filled base film using a roller. This non-contact process prevents contamination of the materials while keeping the final product free of water.
