datalase ltd has developed a broad portfolio of products which enable laser coding of virtually any substrate. this range of unique patent protected materials are integrated into water based, solvent based, oil based or uv curable coatings and  applied via a broad range of printing processes, including flexography, gravure, pad and screen. coding with a low energy laser results in an irreversible colourchange from white or clear to black, or clear to white, enabling printing of high contrast text, graphics, barcodes and qr codes.  the coatings can be successfully activated beneath barrier layers such as laminates, waxes or varnishes without compromising the integrity, providing a secure, indelible, tamper resistant code that is integral to the product or packaging. sourcehttpwww.datalase.com
