|PureFlex Single-Use Process Container Films|
PureFlex™ Single-use process container films are flexible, robust and chemical resistant materials used in the construction of our single-use process containers, including Mobius® assemblies and NovaSeptum® sterile sampling products.
Single-use containers made with PureFlex™ films are employed throughout the biopharmaceutical production process and are free of animal derived components.
PureFlex film is a high purity, medical grade, coextruded film designed to provide strength, flexibility (with maximum resistance to flex-crack), excellent gas barrier performance and inert contact. The fluid contact material is made of ultra low density polyethylene (ULDPE). The gas barrier is made of polyethylene vinyl alcoholcopolymers (EVOH). The outer layers are made of ethylene vinyl acetate (EVA) and ULDPE. PureFlex film contact layers comply with the Food and Drug Administration (FDA) regulation 21 CFR 177.1520.
For particularly demanding applications often encountered in large volume operations (>500L), additional robustness may be required to assure single-use process container integrity. PureFlex™ Plus film is constructed with a tough, linear low density polyethlene (LLDPE) outer layer. This rugged outer layer increases the film's resistance to leak formation through abrasion, puncture, stretching, and tearing. The inner layers, including the product contact layer, are identical to PureFlex™ film, maintaining the same extractables profile and gas barrier properties.
