Covestro unveils Autentium®: an innovative step towards the future of currency printing

The first polymer banknotes made their debut in the late 1980s. They reformed cash transactions with their modern design, allowing for new security features that were impossible with paper. Over time, countries such as Australia, Canada, and the United Kingdom have fully transitioned to polymer banknotes as their primary currency medium. Despite this progress, most banknotes worldwide are still made from paper and cotton composites, materials with inherent limitations such as a comparable short lifecycle and limited recyclability.



In response to the growing demand for sustainable solutions in currency printing, Covestro is introducing Autentium®, an innovative polymeric printing substrate. Designed exclusively for currency printing applications like banknotes, Autentium® combines cutting-edge anti-counterfeiting technology with a recyclable mono-material design.


"The launch of Autentium® represents a significant breakthrough in currency printing, offering an innovative, recyclable polymeric substrate that excels in printability, durability and is more sustainable," says Daniel Hentschel, Global Segment Manager for ID & Security Printing at Covestro.


Key Features of Autentium® include:

Exceptional printability: It supports secure printing techniques such as intaglio and offset, enabling embossed structures and therefore tactile security features that differ from traditional paper and existing polymer substrates.

No coatings or primers needed: Its secondary properties as a hot-melt adhesive contribute to superior ink adhesion without requiring additional primers or coatings, streamlining the printing process and improving durability.

Water & Stain Resistance: The polymer absorbs only minimal moisture, which contributes to a low static charge, while at the same time being resistant to contamination.

Advanced laser engraveability: It allows precise micro-engravings, providing advanced anti-counterfeiting measures and enhancing currency security.

 

As a single-polymer solution, Autentium® is recyclable, addressing the demand for sustainable materials in banknote production. Its high tear propagation resistance and excellent ink adhesion contribute to extend the lifespan of printed currency and can help reducing the environmental impact and conserving resources.


Furthermore, its durable composition can translate into long-term costs savings by minimizing replacements, making it an ideal choice for governments and the public sector that prioritize security and environmental responsibility.

Today's KNOWLEDGE Share Researchers Identify Plastic-Degrading Microbes in Mangrove Soil An international team of researchers has developed a novel method to select bacteria from mangrove soils capable of transforming plastic. This breakthrough offers a potential new approach to tackling plastic waste pollution. By analyzing the effects of polyethylene terephthalate (PET) particles and seawater intrusion on the microbiome of mangrove soil, the team was able to cultivate a collection of PET-degrading microbes. With plastic pollution reaching alarming levels globally, even in remote ocean environments, ecosystems like mangroves—crucial biodiversity hotspots—are under threat from various stressors, including plastic contamination. “Mangrove ecosystems are exposed to significant plastic pollution, and their soils harbor diverse microbial communities, including those with potential plastic-degrading capabilities,” explained Diego Javier Jiménez Avella, a research scientist from the Micr...

Today's KNOWLEDGE Share MCG increases biomass content of polycarbonate diols Mitsubishi Chemical Group (MCG) has introduced grades of its Benebiol biomass-based polycarbonate diols that have a higher biomass content. The product is primarily used in the manufacture of polyurethane resins for coatings in sectors such as automotive, furniture and outdoor products. It is also used in the production of artificial leather. Existing Benebiol grades had a bio-based content of 20-50%, but the new HSS and NLDS grades have a biomass content in excess of 80%. Some of its previous petroleum-derived grades have also been converted to biomass, as the NLS grades. This, the company said, allows it to offer bio-based grades of all its Benebiol products. The shift to biomass-based raw materials while maintaining high-quality functions will contribute to our customers’ efforts to achieve sustainable manufacturing. source:MCG/www.utech-polyurethane.com
