Introducing a brand-new, scalable range of single-use bags. The new product family Flexsafe enables the implementation of single-use bioprocessing throughout all steps of drug manufacture, from process development to production, in upstream and downstream – all using just the one innovative polyethylene film. Flexsafe is based on a multilayer, proprietary polyethylene (PE) film, called S80, and has been developed in close collaboration with resin and film suppliers. A standardized cell growth assay has been used to optimize film formulation, determine the operating ranges for extrusion, welding and gamma-irradiation processes and to establish specifications and process controls. The optimization of the resin formulation, the complete control of raw materials, the extrusion process and the bag assembly guarantee lot-to-lot consistent cell growth performance. The bags enable safe and easy-to-use operation, even in the most demanding applications such as liquid shipping and large-scale stirred bioreactors.
