FluroTec® Plungers

An investment in drug purity

West FluroTec® barrier film is the premier choice to protect drugs from contamination by providing an effective barrier minimizing interaction between the drug and the closure while maintaining container closure integrity. In addition, the fluoropolymer film reduces absorption and adsorption of the drug product, an important benefit for maintaining the potency and shelf life of most drugs. 

West FluroTec Plungers can:

  • Improve the shelf life of a packaged drug
  • Reduce visible and subvisible particulates
  • Improve compatibility of the closure and the drug

FluroTec film is applied during the molding process and is conformable to complex-shaped closures, which are typically required for dry powder and lyophilized applications. Lyopholization closures with West FluroTec film are available in a single-vented design that is proven effective in eliminating mechanical twinning, the interlocking of double-vented stoppers during processing.
