Transparent inorganic barrier layers deposited on polymer films are of considerable commercial interest in the food and medical device packaging industries. For these applications, the nanocomposite materials must provide an effective gas barrier against oxygen and moisture to preserve the packaged product. When, however, the packaging film will experience a moderately high temperature during either usage or fabrication, the gas barrier properties of the film are retained. In this study, the effect of a moderate heat treatment on the structural and gas barrier properties of aged SiO x coatings on PET have been investigated using scanning electron microscopy, atomic force microscopy and gas permeation measurements.
