This innovative technology developed by CST enables new security features and makes identification documents even safer than before.
CST was founded in 2010. The transaction is one of the first projects of Covestro´s strategy to invest in start-upsDr Thorsten Dreier, Global Head of the Specialty Films business at Covestro, said: “With this step, we are strengthening our position as an innovation driver in special films for ID documents. With the new partnership and the introduction of Makrofol ID OVM films, we are creating a new degree of security.”
Covestro has many years of experience in the development and production of films for identification documents.
CST Founder Cosimo Prete added: “We value Covestro as a very innovative partner in the development of film solutions for the production of identification documents and look forward to working together in this growing market.”
Covestro and CST have been working together in this field since 2016. Last year, Covestro introduced the transparent Makrofol ID OVM film to the industry. The OVM material technology creates a completely new colour change effect, which is a very strong level 1 security feature.
The new film can be integrated into existing card manufacturing processes without further modifications.
