Security printers and smart card manufacturers have to increase safety measures constantly in order to safeguard sensitive information incorporated in their products. In order to protect passports, ID cards or smart cards against counterfeiting, tampering and unautorized access state of the art high-tech materials need to be employed.
One essential component in the manufacturing process of these documents are adhesives and adhesive tapes used to bond various layers together, such as the cover page, inlay in passports and chips in smart cards. These tapes must meet strict requirements for durability, adhesion, and resistance to tampering. This is where Lohmann comes in, as a leading provider of secure high-tech adhesive solutions and customized services for security printing and smart card manufacturing industries.
Our innovative solutions help to combat counterfeiting and increase efficiency during the lamination process while realizing new security features. Furthermore, our DuploTEC® SBF adhesives offer an excellent adhesion to recycled materials such as Ocean Plastic, PLA and PVC thus enabling our customers to reduce the environmental footprint of their products.
Lohmann offers elegant bonding solutions for the following main applications
We do this by partnering with our customers in order to create mutually beneficial bonding solutions.
Lohmann offers innovative adhesive tapes that provide a secure and reliable connection between chip modules and antennas while reducing the environmental impact. We help card manufacturers improve their production process while reducing supplier dependency and increasing output. With DuploTEC® SBF, we offer a solvent-free thermoset transfer film that is easy to use and can be electrically conductive in the z-direction. This film can be used on in-use equipment, making it an efficient and cost-effective solution for any card manufacturer. With DuploTEC® SBF, card manufacturers can reduce their environmental footprint while still creating high-quality smart cards.

Lohmann helps passport manufacturers create secure connections between passport cover, inlay as well as inner pages and realize new material combinations. The efficiency is increased during the cover page lamination process, without the typical disadvantages of liquid bonding (no aspiration, no need for cleaning). Whats's more, thanks to the extremely low activation temperature ( > 70 °C), the material is protected and energy is saved. Thanks to its special adhesive design the adhesive strength is immediately available and the material can be directly processed. With our adhesive tapes, we offer the most flexible, thermoset adhesive that supports high-speed, roll-to-roll processes. With that, our customers achieve their production goals while maintaining the highest standards of security and quality. All products can be provided directly on e.g. cover or inlay materials.
