  • Patent number: 11192343
    Abstract: An irreversibly self-destructive security packaging water soluble film and method for manufacturing the same. The water soluble packaging film is embedded with various security elements, which will get irreversibly destroyed upon final usage as the whole package along with its contents will dissolve in water. This process of self-destruction will control the duplication of the package or alteration of the product inside the package.

  • Publication number: 20180015643
    Abstract: A water-soluble film (WSF) system comprises at least one active material embedded/entrapped in the film so as to provide precise and desired release of the at least one active material therefrom. The at least one active material includes detergents, enzymes, softeners, perfumes, pesticides, fungicides, active ingredients, dyes, pigments, hazardous chemicals, active agents for cleaning laundry, dishes, floorings, walls, furniture, fluffs, pulp, and combinations thereof. Online and offline processes can be used for the manufacture of multi-layered WSFs with or without liners. The WSFs can be formed in desired shapes to selectively entrap interacting/non-interacting materials and combinations thereof. The process also provides options for the use of a wide range of raw materials, liners such as paper, film, foil, fabric, etc.
