The combination of high transparency, higher shatter resistance than glass and excellent moisture barrier makes TOPAS® COC particularly attractive for prefillable pharmaceutical primary packaging. The material is also characterized by high purity and excellent biocompatibility.
Examples of applications include prefillable syringes and vials as well as a variety of prefillable containers that can be used, for example, as part of injection systems.
Injection molding and injection blow molding/stretch blow molding are typical manufacturing processes for this type of pharmaceutical packaging.
In addition, TOPAS® COC is increasingly used for pharmaceutical blister packaging due to its high transparency, biocompatibility and excellent moisture barrier.
