Self-destructive irreversible security packaging film

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.

1 . An irreversibly self-destructive security packaging water soluble film for packages or the like, comprising one or more layer(s) of water soluble film and at least one inbuilt security element embedded or entrapped or imparted in at least one layer of the WSF forming a part of the security package which will destroy itself irreversibly during final usage after dissolving or dispersing in water. 
     
     
         2 . The security packaging WSF according to  claim 1 , wherein more than one security elements of similar and/or dissimilar properties are embedded/entrapped or imparted in one or more layers of the WSF. 
     
     
         3 . The security packaging WSF according to  claim 1 , wherein the said security element(s) is/are of overt nature or of covert nature. 
     
     
         4 . The security packaging WSF according to  claim 1 , wherein the WSF is single layered or multi-layered made of raw materials selected from polyvinyl alcohol copolymer ionomers, polyvinyl alcohol homopolymer, non-ionomeric polyvinyl alcohol polymer, polymethacrylate, polyvinyl alcohol, polyacrylamide, polymethacrylamide, polyacrylic acid, polymethacrylic acid, polyurethane, polyethyleneglycol, polyvinylpyrrolidone, proteinaceous binders such as gelatin, modified gelatins such as phthaloyl gelatin, polysaccharides such as starch, gum Arabic, pullulan and dextrin, and water-soluble cellulose derivatives such as methyl cellulose, hydroxy propyl cellulose, hydroxy propyl methyl cellulose, hydroxy propyl ethyl cellulose, hydroxy ethyl cellulose, carboxy methyl cellulose either alone or combinations thereof. 
     
     
         5 . The security packaging WSF according to  claim 1 , wherein the said WSF is cold water soluble, warm water soluble, hot water soluble or non-soluble depending upon the formulation. 
     
     
         6 . The security packaging WSF according to  claim 1 , wherein said security element(s) is/are selected from optically variable pigments, multi-layer thin-film interference pigments, liquid crystal pigments, holographic pigments, interference coated particles, thermochromic pigments, photochromic pigments, luminescent compounds, magnetic compounds, infrared-absorbing compounds, UV-absorbing compounds, magnetic compounds, micro-engraved or microtextured flake pigments, forensic marking compounds, dyes, RFID taggants, nano-particles, nano-tracers, security markers printed security features like barcodes, metallized fibers, metallized/demetallized texts, active molecules, and DNA taggants. 
     
     
         7 . The security packaging WSF according to  claim 1 , wherein said security element(s) is/are light source readable, machine readable PCR, or otherwise readable by any mechanical, electrical or digital device. 
     
     
         8 . The security packaging WSF according to  claim 1 , wherein the security elements are printed or embossed on WSF forming a part of it. 
     
     
         9 . The security packaging WSF according to  claim 8  wherein the security elements are holograms, barcodes, or metallized/demutualized microtexts. 
     
     
         10 . The security packaging film according to  claim 1  wherein the security packaging film is converted into a self-adhesive web and further converted into a printed seal with a barcode including 2D or 3D barcode forming self-adhesive label/seal used for securing the openings of a package or a bottle.
