Cell Growth
Flexsafe® bags ensure excellent and reproducible growth behavior of the most sensitive production cell lines. The optimization of the resin formulation and the complete control of our raw materials, the extrusion process and the bag assembly guarantee a consistent lot-to-lot cell growth performance.
To avoid cell growth issues that have been reported by several users of single-use bags1,2 and to ensure batch to-batch consistency, it is important to optimize and control the concentration of antioxidants. In close collaboration with polymer, additive and film suppliers, we developed a new polyethylene film, called S80. Applying a standardized cell growth assay3,4, the raw material composition and film formulation was optimized especially for critical upstream applications.
As a result, Flexsafe® bags are designed to excel thanks to:
| Optimized antioxidant package | => | Excellent cell growth of the most sensitive cells |
| Use of pharmacopeia-listed antioxidants only | => | Simplified toxicology assessment |
| Zero slipping agents | => | No risk of interference due to these agents |
| Mechanical anti-blocking | => | Reduces stickiness, facilitates extrusion and bag handling |
| Meaningful specifications and process control from polymer resin to finished bag | => | Reliable and reproducible growth performance, well-characterized extractables profile |

Full Control of Manufacturing Process
The current industry practice of using resins or films based on trade names does not provide true control of polymer and additive formulations. Therefore, we established a strong collaboration with leading polymer, additive and film manufacturers to access and control the formulation of our polymer and additive package and to define and control the operating ranges for extrusion, welding and gamma-irradiation processes.
Flexsafe® is the first bag on the market that underlies complete control and traceability of all resins, additives and the entire manufacturing process:
Based on our unprecedented material science and process control approach, you can rely on excellent and reproducible growth behavior, even for your most sensitive cell lines. This has been confirmed by the recently published Dechema study* and biopharma companies worldwide using their specific cell lines. Further, no residual amounts of bDtBPP, a cytotoxic leachable, was identified in WFI extracts of Flexsafe® bags.

Robustness
Flexsafe® meets your requirements for outstanding robustness and ease of use at all steps of your manufacturing process. The film’s strength and flexibility provide consistent performance and easy handling – even in the most stringent applications like cell culture, long-term storage or shipping of drug products.
Superior Strength and Flexibility
The thickness, strength and flexibility of the new S80 film enhances the mechanical robustness of Flexsafe® bags, making it ideal for all bioprocessing applications. The strength of Flexsafe® bags significantly reduces the risk of accidental damage to the bag due to inappropriate handling. Its flexibility enables convenient installation and self-deployment of the bag in its container.

Flexsafe® 3D Bags | Safe and Easy-to-use for Storage applications
Due to its well-characterized and consistent extractable profile, the use of Flexsafe® 3D Bags allows a safe long-term storage for all fluids from upstream, to downstream and final filling steps.
Thanks to the combination of the flexibility of the S80 film and the self-deploying accessory, the bag can be filled to its full volume with no operator manipulation.
