The PET is the most economical solution for the surface of capacitive and resistive input systems. However, it also offers the least protection against vandalism.
When the input system itself is also made of PET, very compact and flexible input systems are possible. A further advantage of polyester film is that it creates an enclosed surface, preventing dirt and liquid from getting into the device.
Polyester films are subject to virtually no limits in terms of design. In screen printing, the film can be designed and printed according to customer requirements. Even photorealistic prints or logos with fine lines are no problem thanks to digital printing.
