Coatings and Films

​By applying coatings and films to stoppers and syringe components, West can improve a closure’s performance. Barrier films can help reduce the risk of interaction between the drug and the stopper, protecting the drug from contamination. Lubricity films can enhance performance on filling lines.

           B2 Coating


B2-coating helps improve machineability in the filling line. B2 is commonly used in combination with West FluroTec® film to provide a silicone oil-free answer to lubrication challenges.
