| 20120061014 | Self-Adhesive Material With A Water Soluble Protective Layer - 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. labels made from the material can be applied by passing them through water and guide rolls, and then between punching die and two way moving vacuum cylinder, and squeeze rolls | 03-15-2012 |
| 20110039985 | METHOD OF MANUFACTURING EMBEDDED WATER SOLUBLE FILM CARRIER - This invention relates to a water-soluble film (WSF) system with embedded/entrapped water-soluble films (WSF). More particularly, the invention relates to a WSF system with actives embedded/entrapped therein such as to provide precise and desired release of actives there from and its method of manufacturing for diverse applications, in which a variety of substances such as detergents, enzymes, softeners, perfumes, pesticides, fungicides, active ingredients, dyes, pigments, hazardous chemicals, active agents for cleaning laundry, dishes, floorings, walls, furniture, fluffs, pulp, etc., and the like can be so embedded/entrapped for such purpose. The invention further discloses novel online and offline process for the manufacture of such multi-layered WSF with or without liners and of desired shapes to selectively entrap interacting/non-interacting materials and their combinations. The process also provides options for the use of a wide range of raw materials, liners such as paper, film, foil, fabric, etc. | 02-17-2011 |
| 20100193146 | High security paper and process of manufacture - The invention relates to high security paper wherein the security feature(s) is/are incorporated into the paper during the manufacturing process using a polymeric film as a carrier for the security feature(s). The invention enables the security feature(s) to be delivered at precise places into security paper used for such diverse applications as bank notes, passport paper, visa paper, security documents, etc. The polymeric film may be a cold water soluble film or hot water soluble film or water insoluble hydrophilic film or a or a non soluble non hydrophilic film or a combination of these films or slit strips of any of these woven or intertwined offline and incorporated into the paper during the paper making process. Alternatively the polymeric film may comprise zone coating or discreet printing or zone extrusion striping or formation of hot water soluble film on preformed cold water soluble film which is then inserted into paper during the paper making process. The combination of polymeric films may be plain or wholly or partially perforated. The security features may be light source readable or machine readable or both. | 08-05-2010 |
| 20100175842 | High strength paper and process of manufacture - A preparation of high strength paper by incorporating a polymeric film into the paper web during the paper making process is provided. The polymeric film is either a cold water soluble film or hot water soluble film or water insoluble hydrophilic film or non soluble non hydrophilic film or a combination of cold+hot+cold water soluble film or cold+hot water soluble film or cold+non soluble hydrophilic film or cold+non soluble hydrophilic film+cold water soluble film or cold+non soluble non hydrophilic film or cold+non soluble non hydrophilic film+cold water soluble film or slit strips of one or many of these combinations woven or intertwined offline and incorporated into the paper during the paper making process. Zone coating or discreet printing or zone extrusion striping or formation of hot water soluble film on preformed cold water soluble film which is then inserted into paper during the paper making process, thus using cold water soluble film as a carrier is also provided. The combination of the water soluble film(s) may be plain or wholly or partially perforated. | 07-15-2010 |
| 20090197341 | WATER SOLUBLE FILM BASED MATRIX TO COLLECT SAMPLES EXTRACTED FROM LIVING SPECIES - 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. | 08-06-2009 |
| 20080206461 | Self Adhesive Material with a Water Soluble Protective Layer - 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. | 08-28-2008 |
