Filling Your Needs: for the good of all people

Health and physical integrity are key resources, as the COVID-19 pandemic clearly demonstrated, further fueling the health megatrend. It now permeates all areas and defines entire lifestyles. We are making an active, significant contribution with our Blow-Fill-Seal technology, aseptic filling machines, special pharmaceutical services, and single-use containment systems.

Blow-Fill-Seal safely, quickly and sustainably produces unadulterated medications, some of which are vital, and a wide variety of healthcare products. Flecotec containment systems protect employees and products in API and (bio)pharmaceutical production from contamination and toxic substances. All our solutions guarantee easy handling and reduce operating errors - in the manufacturing process, during transport and application. This is what we like to work for and what spurs us on again and again to top performance.
