Viwit’s sterile blow-fill-seal (BFS) eye drops manufacturing facility is established in 2021. The BFS production line fulfills the need for an advanced aseptic manufacturing process using the state of the art Rommelag 434 BFS system. Pharmaceutical grade low-density polyethylene (PE) is used to ensure product quality and prevent leachable and leakage. A strip of 15 doses attached to each other can be created and filled within a few seconds. Every single BFS ampule is detected for leakage to ensure the integrity of the dose.

This automated, streamlined, continuous operational process assures a consistent medication dose as well as achieves the goal of obtaining the highest degree of sterility. BFS technology is ideal for high-speed, high-volume production and is cost-effective as compared to other options such as glass and 3-piece ampules.
