Banknote paper, as well as other sophisticated papers for passports and official documents, must have specific features to ensure security and reassure users. To achieve these two goals and to resist wear-and tear, banknote papers have traditionally been made with cotton or other annual plants.
However, resistant cellulose made from cotton provides with exceptional strength. They are therefore the prime choice to manufacture bank notes, passports and other official documents. Cotton-based papers are used for well over 95% of banknotes in the world. Twin-screw processing is ideal for making these paper pulps because it ensures consistent quality and features and can achieve the right “look-and-feel” that people expect. Also, the twin-screw process makes it easier to include watermarks, security threads or chemical tracers at the papermaking phase to make more secure banknotes that are difficult to counterfeit. With twin-screw equipment supply, banknotes of cellulose composition have established their reputation in many areas of the world such as France and internationally England, Russia, South Korea, China and other countries.
