Covestro will show its polymer technologies that help reshape the security, durability, and sustainability of identity documents and banknotes at TRUSTTECH 2025, which will take place at Paris, France on December 2-4. Highlighted exhibits will include Certevo and TPU passport covers.

Certevo: Advancing document security and circularity

Covestro’s Certevo, successfully launched in 2024, has proved how it can be integrated into real-world security printing applications including certificates, diplomas, vehicle registration papers, and fiscal documents.

Engineered for high-security substrates, Certevo combines reliable print performance and precise laser engravability in a fully recyclable, single-polymer design, helping document producers enhance security while supporting circularity in material use.

“It tackles two core challenges at once: enhancing document security through excellent offset intaglio printing tactility, and laser personalization, while advancing recyclability and circular design. Its outstanding durability and print receptivity extend document lifespan and help conserve valuable resources across the entire value chain,” explained Daniel Hentschel, Global Segment Manager for ID & Security Printing Specialty Films at Covestro.

Laser-personalized TPU passport covers

Covestro’s new laser personalization concept for passport covers, made from thermoplastic polyurethane (TPU), enables document manufacturers and personalization hubs to customize covers using standard laser-engraving systems.

This innovation transforms the cover into an active security feature, enhancing each document’s protection and uniqueness. The process can also produce tactile Braille markings, reflecting Covestro’s commitment to both authenticity and accessibility in passport design.

Secure Color Personalization technology

Addressing a key industry challenge, Covestro’s Secure Color Personalization technology enables decentralized, color portrait personalization without compromising security. The process combines digital printing and laser personalization with specialized polycarbonate overlay film to structurally integrate portraits into ID documents.

This three-step "tattooing" technique creates tamper-evident documents with unique tactile patterns, while supporting faster local issuance and greater system resilience.

“This technology delivers the security benefits of centralized production with the flexibility of decentralized personalization,” said Hentschel.
