A new quasi‐isostatic permeation test method has been developed for aroma barrier testing. Aroma concentrations are measured as a function of time, while the compounds diffuse from the source cell containing the model aroma solution through the tested material to the receiving cell. This method is applicable for testing various materials such as uncoated and coated paper/paperboard, and polymer films. The method utilizes automatic gas sampling from the test cells to gas chromatography. Copyright © 2007 John Wiley & Sons, Ltd.
