What is Blow-Fill-Seal (BFS) and what makes Unither the world leader?

⏱ 1 min read

Blow-Fill-Seal (BFS) is a fully automated pharmaceutical process that allows the production of sterile single doses with no direct human intervention. The container is first blown from plastic granules, then filled and sealed aseptically within seconds, in a closed and controlled environment.
This unbroken production method drastically reduces the risk of contamination and guarantees a high level of sterility, making it a reliable alternative to glass packaging for many drugs, medical devices, and vaccines.

Unither Pharmaceuticals is currently the world leader in BFS thanks to:
