Adding Value through Improved Performance
West’s ongoing research and pharmaceutical processing expertise have made West and its affiliates the worldwide leaders in value-added technologies that improve the chemical and functional properties of stoppers and syringe components.

The documented, validated Westar^® process provides customers with stoppers and syringe components delivered ready-to-sterilize or ready-to-use.

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.
