FluroTec® barrier technology

FluroTec® film, West's superior barrier technology, is a leading product in all pharmaceutical markets.

West FluroTec film provides an effective barrier against organic and inorganic extractables, minimising interaction between the drug and the closure while maintaining container closure integrity. The fluorocarbon film reduces absorption and adsorption of the drug product, an important benefit for maintaining the strength and shelf life of most drugs. In addition, the low surface energy of FluroTec film, in combination with B2-Coating, provides lubricity without the need for free silicone oil; eliminating one potential source of particulate contamination.

FluroTec film reduces stopper clumping during autoclave sterilisation and helps prevent stoppered vials from sticking to the shelves in lyophilisation chambers. FluroTec film is applied during the molding process and is conformable to complex-shaped closures, which are typically required for dry powder and lyophilised applications. Lyophilisation closures with West FluroTec film are available in a single-vent design that has proven to be effective in eliminating mechanical twinning, the interlocking of double-vented stoppers, during processing.

Your benefits

By choosing West FluroTec stoppers and plungers, you may be able to:

  • Improve the shelf life of your packaged drugs
  • Reduce visual and subvisual particulates
  • Improve the compatibility of the closure and the drug, leading to:
  • Reduced risk of packaging-related failures
  • Reduced interaction of extractables from the rubber
  • Reduced accumulation of leachables in the drug formulation
