3D Bags

Flex4Sure™ 3D Bag Systems incorporate chambers manufactured from INFUFLEX film from Renolit. This co-extruded film has a PE contact layer and offers robustness, a well-characterized extractable profile, high clarity, and excellent chemical resistance. In sizes from 100L to 1000L, Flex4Sure™ 3D Bag Systems are adapted to fit various existing rigid storage totes. The SaniSure® Flex4Sure™ 3D Bags eliminate CapEx for this hardware as they can be integrated quickly into any current process for storage of fluids used in biopharmaceutical manufacturing. Standard Flex4Sure™ 3D Bags are available with Cellgyn® TPE tubing and MPC connectors for rapid delivery or can be integrated into custom assemblies designed to meet your application.
