Understanding BFS Packaging
What Is BFS Packaging?
Overview of the BFS Process
Blow-fill-seal (BFS) packaging is an advanced aseptic technology that integrates container formation, filling, and sealing into a single automated process. This method ensures a high assurance of product sterility, making it ideal for packaging needs for pharmaceutical liquids. The process begins with pharmaceutical-grade thermoplastic resin, which is melted and extruded into a tubular shape called a parison.
