Blow-Fill-Seal

Blow-Fill-Seal (BFS) is an advanced aseptic process used to fill-finish billions of sterile liquid pharmaceutical doses every year in dozens of markets. In a 3-8 second continuous process (varies by machine model), a plastic container is formed from heated resin, filled with the drug product, and then aseptically sealed.

BFS is designed to scale to any output. A high-end BFS machine can fill and finish up to 15,000 units an hour, with high uptime and low overhead. It uses a very simple supply chain of typically only 1-2 facilities, and its only key raw materials being pharmaceutical-grade virgin resin. 

BFS has always been recognized for its efficiency and low manufacturing cost. But a recent study has also highlighted its low carbon footprint and wastage as compared to other standard liquid delivery formats. Much of these benefits are realized because BFS only relies on virgin pharmaceutical-grade resin, and not energy intensive materials such as glass, metal, and rubber. Learn more here.

BFS is a growing around the world as a trusted fill-finish process for sterile liquids because of its advantages in efficiency, cost, and reliability.
