These closures were polypropylene closures with ethylene vinyl acetate (EVA) liners as disclosed in U.S. Patent 5,306,542. After being allowed to equilibrate for 14 days at 68F/50% RH storage, the total container CO 2 transmission rate was measured by placing the container within a sealed vessel with a known capture volume. The sealed vessel had two ports through which nitrogen carrier gas flowed in through one of the ports and exited the vessel from the other port. The exit port was directed to a Mocon C-IV CO 2 test machine used for detecting the amount of CO 2 . The quantity of CO 2 was measured for a period of time, from which the CO 2 transmission rate was determined.
