Multilayer structures suitable for food packaging is provided, wherein barrier layers of SiO and SiO.sub.2 are successively vacuum deposited on a resin substrate such as PET film. This combination of silicon oxide layers provides economical, color-free, microwaveable packaging. Barrier properties of the packaging after retorting can be improved by incorporation of a dopant of metallic material in the SiO.sub.2 layer.
