摘要:
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.

摘要:
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).

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.

The invention relates to a preparation of high strength paper by incorporating a polymeric film into the paper web during the paper making process. 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. The invention also relates to 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. The said combination of the water soluble film(s) may be plain or wholly or partially perforated.
