  • 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.

  • Patent number: 8673236
    Abstract: The invention relates to a water soluble film based matrix for collecting blood samples, urine samples, serum samples or any other type of samples extracted from living species; so as to avoid cross infection or spillage of samples during transportation of said samples. These samples can then used for further detection of virus, bacteria, finding new molecules, diagnosing genes or extraction of DNA. Also, said matrix will dissolve during analysis of the sample and thus there will be no disposal problems.

  • Publication number: 20120061014
    Abstract: A face material is coated with a pressure sensitive adhesive which is in turn coated with a water soluble protective layer. The opposite printed side of the face material may be coated with hydrophobic lacquer. The adhesive is dried or cooled before the protective coating is applied. The protective layer is applied by extrusion or solution casting. Alternatively a reusable liner can be coated with the protective material and adhesive before the protected adhesive is transferred onto a face material.

  • Publication number: 20110266711
    Abstract: A pin-hole free multi-layered film having partially or fully water soluble films layered with substantially pin-hole free barrier coatings that are partially insoluble or fully water-soluble or dispersible. The film may include detachable and/or non detachable substrates. The process for manufacturing the film is versatile to accommodate embodiments such as on-line/off-line processing, selective barrier print-coating in flexo-gravure processing individually or in combinations involving especially designed roto-gravure cylinders/flexoplates for multi station registrations and/or multipass operations to achieve substantially pin-hole free films, etc. The barrier coatings may be continuous or discrete and/or selective, based on the end use application.

  • Publication number: 20090208559
    Abstract: A device for controlled delivery of an active ingredient to a receiving site (1) such as a plant, human or animal. The device comprises a filmic substrate including a water soluble carrier layer (2) disposed between first and second water soluble control layers (3, 4). The second control layer (4) of the filmic substrate is provided with adhesive (5) on the side remote from the carrier layer (2) for attaching the device to the receiving site (1) with the first control layer (3) outermost. The first and second control layers (3, 4) having perforated regions (9, 8) whereby the carrier layer (2) can be dissolved by wetting the first control layer (3) with an aqueous medium that passes through the perforations (9) of the first control layer (3) releasing the active ingredient into solution that passes through the perforations (8) of the second layer (4) to come into contact with the receiving site (1).
