Until now gas permeation measurements can take several hours or even up to a couple of days for high-barrier technical applications. Therefore a method that allows a quick measurement of the polymer films' barrier properties has been developed. Using this method it is possible to reduce the duration of the permeation measurement to only a few minutes. The rapid feedback on the permeation properties will make it feasible to accomplish an iterative development of new formulations for films directly at the production line. A further application for this atline measurement technique is the monitoring of the barrier properties in the quality control. The investigations show for several barrier properties a good correlation between the results of accelerated and standardized tests. These results and the basic aspects of the rapid permeation measurement method are discussed and presented.
