Eco-friendly flexographic ink for anti-counterfeiting

The challenge to prevent the counterfeiting of documents is a research area that demands innovative techniques. A new study reports the use of fluorene-based Schiff base (FBH) prepared via a simple, one-step and cost-effective method as a thermally stable and biocompatible pigment for environment-friendly, water-based flexographic ink for potential application in security printing.Get more news about china flexographic ink,you can vist our website!

Invisible fingerprint
The flexo ink coating and print on the UV dull security paper were invisible in the daylight but displayed bluish-green fluorescence under UV light. The functional ink formulation can also be smartly-utilised in stamp/ink pads to obtain invisible fingerprint for detecting forgery.
Once again Werner & Mertz, in cooperation with its Reyclate Initiative partners, has pioneered a new printing ink system for applications way beyond its own industry. With the ink manufacturer Siegwerk Druckfarben AG & Co. KGaA, the EPEA Switzerland GmbH (Environmental Protection Encouragement Agency), and the global packaging and paper company Mondi, the Mainz cleaning products maker has developed a recyclable printing ink system for flexography which has been awarded Material Health Certification (MHC) GOLD. The use of sustainable printing inks is a significant step in designing packaging according to the Cradle-to-Cradle principle. “In the spirit of the Open Innovation approach promoted by the Werner & Mertz Recyclate Initiative, the certified ink series with the product name ‘NC 270’ is not patented. It may be and should be used by other companies,” said Torsten Haas, Packaging Developer at Werner & Mertz.

Closed cycles down to the smallest detail

Within the Recyclate Initiative, all packaging is developed in accordance with the Cradle-to-Cradle principle, that is, designed from the start to go into a closed material cycle and to pose no risk to human health and the environment. Sustainable and healthy raw materials are just as important as packaging’s recyclability after its use phase. That’s why, in addition to the bottles and caps made of recyclates, sustainable printing inks are critical for a product’s recyclability. With the Material Health Certification, the safety of the solvent-based printing ink NC 270 is now confirmed scientifically for biological cycles. Gold certification is awarded exclusively to products that “do not contain carcinogens, mutagens or reproductive toxicants with plausible exposure routes,” according to the MHC.

“The New Green Deal of the EU Commission calls for safe and reliable plastic packaging that is sustainable for coming generations and the environment. This project is the guide to that goal. It has been confirmed by an independent third-party with the only certification system for cycles,” said Albin Kälin, CEO of EPEA Switzerland, an accredited assessment body for Cradle-to-Cradle Certified™ and MHC Standard.
