A formal architecture for public authentication, trained-handler verification, and machine-readable controls on advanced polymer substrates.
Q&T's proprietary multilayer architecture (Vietnamese Invention Patent No. 1-0041088 B) encloses optical security devices (OVDs) within the polymer laminate rather than applying them onto exposed exterior surfaces, delivering structural shielding against friction, crumpling, and solvent attack.
A high-clarity outer biaxially oriented polypropylene layer that shields against surface scuffing, everyday wear, and chemical exposure.
Diffractive optical devices (OVD / KINEGRAM®) encapsulated within the substrate core, reducing direct edge exposure and peel-related vulnerability.
High-tensile biaxially oriented core combined with uniform opacification layers, establishing dimensional stability and baseline tear resistance.
A clear taxonomy distinguishing Q&T proprietary substrate technology, partner optical integrations, and compatible security features.
Proprietary substrate formulations and multilayer architectures engineered, patented, and manufactured by Q&T.
Engineered BOPP currency-grade substrate with superior tensile integrity and print receptivity.
Patented laminate engineering embedding optical devices inside the polymer matrix.
High-transparency optical aperture zones formed natively during substrate opacification.
Diffractive optical elements from LEONHARD KURZ (Germany), integrated within Q&T substrates under the two companies' Project Development Cooperation Agreement.
LEONHARD KURZ • KINEGRAM®High-security diffractive microstructure foil for unambiguous public verification (Level 1).
High-resolution color-shifting kinematic imagery providing unmistakable visual authentication.
Optical devices sit beneath the outer BOPP barrier, reducing raised surface interfaces.
Advanced authentication features compatible with PolySecure®, deployable to issuing authority specifications.
Designed for integration with modern cash-processing systems, subject to programme-specific validation (Level 2).
Engineered capability to host covert microscopic taggants for laboratory authentication (Level 3).
Research pathway exploring ultra-thin embedded circuitry for serialized lifecycle tracking.
Relative durability results from accelerated circulation testing, alongside the certified management systems that govern production.
Measured for the PolySecure® substrate in the independent Substrates Durability Assessment (May 2025): QT versus the tested UNK reference substrate.
A substrate-level mechanical assessment of soil resistance, crumpling and wear. Embedded optical devices were not part of the tested scope.
Rigorous security management system certification for facilities producing secure document substrates.
Audited physical security, supply chain chain-of-custody, and production integrity controls.
ISO 9001:2015 certifies Q&T's quality management system for the certified production scope.
A management-system certification. It is not evidence of any specific material or print performance property.
Q&T and LEONHARD KURZ signed a Project Development Cooperation Agreement to integrate KINEGRAM® optical security technology into Q&T's embedded polymer substrate platform.
The companies will jointly develop the process and product toward industrial maturity.
