Covestro is developing solutions with films that improve security and enable efficient production of cards. The company is presenting new and sophisticated products for ID cards. Covestro's position as a leading supplier of thermoplastic films for high-value documents derives primarily from the fact that the company continuously responds to the latest trends in this innovative sector. To meet the many different demands of card manufacturers, Covestro has developed a range of polycarbonate films under the Makrofol~R and Bayfol~R brands and the Platilon~R ID range of thermoplastic polyurethane films (TPU). "Multi-layer TPU films and combinations with polycarbonate films for applications where excellent mechanical strength and durability are crucial are new to our portfolio," says Georgios Tziovaras, applications engineer in special films at Covestro. One example is the thin fold of passports, which consists of a Platilon~R ID composite film and is laminated inside onto the data page. The production process is highly efficient and the composite is also long-lasting. Documents can be opened and closed again any number of times without affecting flexibility or tearing at the fold.
