Fortress Paper Ltd. announced that the Central Bank of the Bahamas has chosen to use Durasafe®, the proprietary banknote substrate of Fortress Paper's wholly-owned subsidiary, Landqart AG ("Landqart"), for the two highest denomination banknotes of its "Crisp Evolution" series. 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.
