Abstract
Deposition of SiOx layers by low-pressure microwave plasmas is an excellent means to add missing barrier functionalities to cheap and material-saving homo-polymeric materials that will increasingly replace expensive multi-layer polymer food packaging. SiOx coatings were deposited in an ECR plasma process on polyethyleneterephthalate (PET) foils using two different precursors, HMDSO and HMDSN. O2 transition rates of less than 1 cm3 (m-2·24 h -1·bar-1) were obtained for the best performing SiOx coatings deposited from O2/HMDSN gas mixtures. First ECR plasma deposition tests on polypropylene (PP) trays show the high barrier potential of SiOx coatings even on three-dimensional polymer food packaging.
