    摘要: 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.
