Fluid Transport & Dispensing

fluid_transport.jpgBags used for storage, transportation or dispensing fluids are prolific throughout the healthcare industry.  These containers are commonly produced from extruded or blown film that is sealed along designated edges.

PVC is used in a wide array of low cost, fluid containing devices, including intravenous (IV) bags, blood bags, feeding bags and dialysis bags. However, plasticizers used to increase flexibility of naturally rigid PVC have raised concerns by the FDA in recent years. In this case, polyolefin polymers such as polyethylene (PE) and polypropylene (PP) are also available as a plasticizer free alternative. PE film is inhert and offers flexibility and tear resistance, while PP provides a higher degree of clarity and excellent barrier properties against moisture and vapors.

Additionally, polyvinylidene fluoride (PVDF) bags, including those made of Kynar® are well suited for sample containment of gases or liquids, or single-use sterile manufacturing operations in bioprocessing. Bags made from PVDF are resistant to a wide range of sterilization processes including ultraviolet radiation and concentrated acids or halogens.
