Synthec® durable banknote paper – toughened up for mechanical strength
Synthec is the enhanced durable banknote substrate for improved quality throughout the banknote’s lifetime. The synthetic fibers and LongLife protective coating of Synthec delivers an optimized combination of outstanding mechanical stability, stiffness, and anti-soiling properties.
Synthec’s synthetic fiber and cotton mix increase resistance against initial and further tearing during circulation and processing to ensure higher mechanical stability. Featuring the LongLife microscopic coating applied to the paper during production, Synthetic effectively protects the surface against moisture and soiling. The intense compression of the LongLife coating and paper during intaglio printing further enhances the banknote’s anti-soiling properties.

Benefits of Synthec banknotes for central banks
Synthec is developed for denominations that require additional resistance against tearing as well as soiling, without compromise to security. Virtually identical in look and feel to cotton banknotes, Synthec banknotes are ideal for displaying attractive security features in a prestigious banknote design. Synthec banknote paper can be exclusively customized to embed watermarks, security threads, and machine-readable elements in order to secure the banknote against counterfeiting.
- Enhanced mechanical stability. Synthec’s optimized synthetic fiber content ensures high mechanical stability while maintaining stiffness, providing durability and tearing resistance to ensure a longer circulation life.
