What do Banknotes and turtles have in Common?

One specific area G+D set out to improve is the durability of banknote materials. The proposition is simple: The longer a banknote lasts, the more sustainable it becomes. But the challenge is to improve durability and thus reducing the need for reprints, while simultaneously maintaining maximum banknote security.
In this episode of Currency Insights, Christoph Mengel elaborates on the requirements for long-lasting banknote substrates, and also introduces two innovative solutions from G+D and Papierfabrik Louisenthal.
