The physical properties required for numerical implementation are studied. The analysis reveals that the solubility of the metallic coating is not required for an accurate water transport analysis, which makes the ILT-based model practical. The model is implemented numerically and the results are compared with the experimentally measured transient water weight gain of PET films with Al </p> <p><a href="../../fulltext/2008/APPL ILT.pdf">Complete article</a> is available to CALCE Consortium Members.</p> <hr><br> <center> [<a href="http://www.calce.umd.edu">Home Page</a>] [<a href="../../">Articles Page</a>] </center> <center><font size="-1">Copyright ýÿ 2008 by CALCE and the University of Maryland, All Rights Reserved </font></center> </body></html>
