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.

Primary packaging components come in intimate contact with drug products – they can affect both drug product and patient safety. Many elastomer components are offered with a FluroTec® film that serves as a chemical barrier to minimize the migration of compounds from the elastomer into the drug product. FluroTec film comprises an ethylene-tetrafluoroethylene co-polymer (ETFE) – selected based upon flexibility, ability to be laminated to an elastomer, and of course, permeability resistance.
