Zeonex cycloolefin polymers (COP) are used as lightweight, breakage-resistant packaging that can be designed to protect protein-based, peptide-based, floating-particle and high-viscosity drugs, as well as contrast media. The material’s high purity and wide-ranging compatibility make it a better choice than glass and other plastics (such as polypropylene or polyethylene terephthalate) for such applications. Zeonex’s mechanical properties insulate it from damage frequently inflicted onto other plastics from steam, ethylene oxide and gamma sterilization. It has a very high transparency, which facilitates a physician’s ability to see the drug relative to its contrast media when dispensing doses to patients.
