Evaluation of PET as functional barrier towards organic compounds

Although PET is a promising barrier material, knowledge about lag times does not exist until now. As this knowledge is essential for the evaluation of PET as functional barrier, the aim of this study was to develop a permeation testing method suitable for the determination of lag times. The lag times of 37 compounds were determined with the developed method. A tested 12 ìm PET film proved to be an effective barrier towards the investigated compounds. The prediction of lag times of organic compounds at different film thicknesses and temperatures becomes possible using the data of this study.
