摘要:
The invention relates to a self destructive irreversible 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 destroyed irreversibly 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 package or alteration of the product inside the package.
摘要:
A process for the manufacture of a water soluble film with at least one embedded active material. A formulation for the water soluble film is cast on a liner at a casting head (28). The cast water soluble film is smoothed and then dried with the at least one embedded active material at a drier (30). One or more additional water soluble films may be cast onto the cast water soluble film at subsequent casting heads (33) to produce a multi-layer water soluble film.

The invention relates to a high security film, optionally in the form of a slit thread or a micro tape, which is then inserted into high security paper such as a bank note paper and the like during the paper making process. The invention envisages a novel method of producing such a high security film using a print transfer method, wherein one or more security features are incorporated on one or more indicia including letters, optionally graphics, during such a production process, using multiple printing stations and lamination.

The invention relates to self adhesive material (SAM) using water soluble film incorporated with surfactants and/or fillers as a protective layer, eliminating the release liner (backing liner). The water soluble film incorporated with surfactants and/or fillers, used as a protective liner, provides easy breakage, faster dissolution as well as easy application to an object. The invention also relates to a process for the preparation of self adhesive material (SAM) without release liner and an apparatus and a method for applying the self adhesive material (SAM) on an object.

The present invention discloses novel pin-hole free multi-layered films consisting of partially or fully water soluble films layered with substantially pin-hole free barrier coatings that are partially insoluble or fully water-soluble or dispersible and methods of manufacturing. The invention further relates to detachable and/or non detachable substrate based multi-layered films with water soluble or partially water-soluble films layered with substantially pin-hole free barrier coatings and methods of manufacturing the same. The process described herein is versatile to accomodate 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. The multi-layered film product with good gas barrier properties optimal tensile strength, percentage elongation and impact strength to withstand mechanical stresses during the processing and at the same time retain their strength and integrity during storage thereby making them most suited for a variety of applications including packaging of detergents, pharmaceuticals, agro-chemicals, food products, etc...

摘要:
This invention relates to a combined water soluble film wherein at least one layer is a solution cast water soluble film on a liner and at least one layer is a preformed water soluble film, preferably a thermally extruded water soluble film. The said water soluble films may be edible or non edible. The said water-soluble film on a liner is coated with a tie-coat to enable coating of a water-based binder used for combining the water soluble films without dissolving/damaging WSF on liner. The water based binder used for combining the said water soluble films may be incorporated with active ingredients like flavours, perfumes, detergents, enzymes, softeners, active agents for cleaning laundry, dishes, floorings, walls, furniture; various agrochemicals like pesticides, insecticides, weedicides, fungicides, bio-pesticides; agro nutrients like urea, fertilizers; dyes, pigments, fluff, pulp, super absorbents and active pharma ingredients like vitamins, drugs, medicine. The said combined water soluble film so achieved will be a substantially pinhole free multi-layered water soluble film of desired mechanical strength at low cost. The invention farther relates to the methods/processes used for producing a cast-extruded or cast-cast combined WSF.
