Q&T’s POLYSECURE® SHIELD Embeds OVDs into Polymer

Hanoi-based Q&T Hi-Tech Polymer is the newest entrant to the market for polymer substrate market, and is already supplying its POLYSECURE® product for Vietnam’s banknotes. At the recent Currency Conference in Bangkok, the company unveiled its latest innovation – POLYSECURE® SHIELD.

POLYSECURE SHIELD is an advanced multilayer polymer security banknote substrate which is designed to enhance the longevity and security of banknotes by embedding the OVD within the polymer substrate structure.

As the company explained, typical polymer banknote substrates feature surface applied OVDs, which are subject to abrasion from handling, mechanical stress from bending and crumpling, and exposure to chemical and environmental contaminants. These factors can lead to a shorter lifetime of the OVD and the withdrawal and destruction of the banknote from circulation, even though the substrate itself continues to be fit for further circulation. They can all be overcome by embedding the OVD with the substrate rather than putting it on the surface.
