West Flip-Off® Seals

Because clean sealing matters

Seals are a crucial part of a vial system. Though Flip-Off® Seals do not have direct product contact, the selection of an appropriate seal is critical to ensuring container closure integrity, drug protection, user convenience and safety. To deliver consistency and extreme precision, Flip-Off Seals are manufactured using the TruEdge® technology production process that includes 100% vision inspection.

Recently revised regulatory standards and emerging quality directives – such as USP <1> and EMA Annex 1 “Manufacture of Sterile Medicinal Products” – bring new considerations to the forefront in seal selection. Partner with West to select the right Flip-Off® Seal for your product.
