| heal.abstract | The permeation parameters of conventional PET films, films coated with SiOx and SiOx-coated films laminated to LDPE were determined for ethyl acetate using the permeation cell/gas chromatography method. Permeation to O-2 and water vapour was also determined to monitor overall changes in the barrier properties of the experimental films. Coating of the PET film was achieved by a 'directed evaporation' method that increased the yield of the coating process from 30-35 to > 70%. It was shown that the SiOx coating increased the film barrier to ethyl acetate by similar to 20-30 times. Permeation values showed low reproducibility, indicating the need for further development and standardization of the 'directed evaporation' web-coating process. The barrier to oxygen and water vapour increased by 20-25 and 12-14 times respectively after coating. The web-coating speed did not seem to influence the barrier properties of the films. Permeation coefficients, diffusion coefficients and solubility coefficients were calculated for all samples. | en |
