This innovative product combines a water-soluble PVOH layer with one or more protection films such as PET film, PE film, ALU film or metallized films which separate from the water-soluble film.
When the sachet is opened, the outer protective layer is removed, leaving an uncontaminated packaging to be thrown away or recycled. The inner dose in a water-soluble film is used directly and dissolves in contact with water, leaving no toxic residue.
