Permeability measurements were performed on several polymeric films used for packaging applications. The results were analysed in terms of the ratio of the permeabilities between twogases. Moreover, recent experimental results and data reported in the literature have been compared with a simple relationship reported by van Krevelen for predicting the transport properties of highmolecularweightpolymers. Finally, a suggestion is made for improving the accuracy of the prediction of the permeabilities for highmolecularweightpolymers.

Abstract
Permeability measurements were performed on several polymeric films used for packaging applications. The results were analysed in terms of the ratio of the permeabilities between twogases. Moreover, recent experimental results and data reported in the literature have been compared with a simple relationship reported by van Krevelen for predicting the transport properties of highmolecularweightpolymers. Finally, a suggestion is made for improving the accuracy of the prediction of the permeabilities for highmolecularweightpolymers.File in questo prodotto:
