Tests were performed on several bags made from fluorinated ethene-propene copolymer film, commonly referred to as FEP-Teflon, to see if they release fluorocarbon vapors, as was recently reported by others. Special attention was given to determining if tetrafluoroethene and hexafluoropropene, the monomer units used to synthesize the film, were released. By use of an instrument that measured total gas-phase carbon, it was determined that at most 0.06 ppm of C of non-methane organic contamination was released into bags of clean air stored outdoors for up to 2 days. A more sophisticated technique was used to confirm that neither of the two precursor fluorocarbons was released into the bag at concentrations above the detection limit of approx.25/sup 0/C in a room as well as one stored in an irradiated chamber at 30-40/sup 0/C. These findings are contrary to those recently reported by another group who found large releases of fluorocarbon contaminants, especially hexafluoropropene, from similar bags. We conclude that no all FEB-Teflon film releases fluorocarbon vapors.
