Containment/delivery systems for sensitive biologic drugs must provide the chemical, physical, and performance properties required to ensure product quality through shelf life. Further, they must be compatible with fill/finish operations, and enable functional performance during administration. Legacy rubber components may no longer meet the increasing technical and regulatory requirements of current and future biologic drug products.

Fluoropolymer-laminated elastomer stoppers and plungers provide enhanced performance for container and delivery systems for parenteral drug products – especially sensitive biologic drug products. Among the many fluoropolymers available, West uses ETFE [poly(ethylenetetrafluoroethylene)] for its FluroTec®–laminated products. Selection of ETFE was based upon ease of moldability and the following factors.

The regulatory landscape in China continues to evolve and become more stringent. In December 2018, the Chinese Pharmacopoeia Commission (ChPC) published: Second Draft for Comments on Guideline for Stability Study of Plastic and Rubber Pharmaceutical Packaging Materials. This guideline comprises part of the results of a research project organized by ChPC in 2016 and is one of the actions taken by National Drug Administration of China (formerly the China Food and Drug Administration, CFDA) to support the previously announced Opinions on Reforming the Review and Approval System for Drugs and Medical Devices (No. 44).
