A structural body has an inner layer formed of a resin which does not transmit light with a specific wavelength, an outer layer stacked on the inner layer and formed of a resin which transmits the light with the specific wavelength, and a fine periodic structure provided on at least part of a surface of the inner layer facing the outer layer and having a plurality of photodecomposition generated convex and concave portions. The plurality of convex and concave portions of the fine periodic structure is formed alternatively, and horizontally and vertically with substantially equal intervals in between along the surface of the inner layer facing the outer layer.

A method of forming a vapor deposited film of a silicon oxide on the surface of a substrate by holding the substrate to be treated in a plasma-treating chamber, and effecting the treatment with a chemical plasma by feeding an organosilicon compound and an oxidizing gas into the treating chamber, wherein the rate of feeding the oxidizing gas is varied while maintaining constant the rate of feeding the organosilicon compound gas into the plasma-treating chamber during the formation of the vapor deposited film. A chemical vapor deposited film is formed featuring excellent adhesiveness, softness, flexibility, oxygen-barrier property and water-barrier property.

Chemical vapor deposited film based on a plasma CVD method and method of forming the film

The present invention is a packaging material composed of a thermoplastic polyester as a constituent material. By adjusting the contents of a dibasic carboxylic acid and its oligomer derived from the polyester to 500 ppm or less, and adjusting sodium to 6 ppm or less and all alkali metals to 30 ppm or less, especially 20 ppm or less, the flavor retention of the packaging material can be markedly increased.
