Polystyrene is a polymer from the styrenics family that offers excellent transparency coupled with a very competitive cost. It has medium mechanical properties making PS rigid and brittle.

The GEM integrates a nano-structuring surface technology that allows the creation of very fine patterns and thus the fight against counterfeiting, either in a discreet and non-reproducible way, or
