Prefilled syringes (PFS) are continuously gaining market share as a convenient form of administering drugs. In particular, PFS made of high-quality polymer such as cyclic olefin co-polymer (COC) has become a well-established alternative because they offer greater design flexibility while reducing the breakage rate throughout the value chain. Andreas Hofenauer and Stefan Krauss at Schreiner MediPharm and Tom Van Ginneken at Schott AG have a discussion on polymer syringes along with functional labels.
