New 50- and 100-dollar notes for the Bahamas

Fortress Paper has announced that the Central Bank of the Bahamas will use the Durasafe substrate developed by their subsidiary Landqart AG for the new 50- and 100-dollar banknotes. These new notes are planned for introduction in 2018. This relatively new material is also used in the new banknote series of Switzerland.

From the press release some more explanation about Durasafe: "Durasafe® is an innovative composite paper-polymer-paper banknote substrate developed by Landqart in cooperation with the Swiss Federal Institute of Technology (ETH) Zürich. Durasafe® is composed of two cotton paper outer layers with a fully transparent polymer core. The polymer core in Durasafe® adds stability and higher mechanical strength properties to banknotes as well as high security features. The substrate's unique properties allow windows to be formed virtually anywhere on the banknote and can contain a watermark and security fibres as well as traditional security features, including easy-to-recognise banknote paper tactility."

Update 11-12-2019: it took a while but the new 50-dollar note was issued on 3 October 2019. According to a press release, this is the first note in the world with a Rapid security thread on Durasafe substrate.
