Abstract: The present invention is a polyolefin packing container having on the inner surface thereof an olefin resin layer that contains an ethylenebis fatty acid amide, wherein the ethylenebis fatty acid amide is bleeding in the inner surface in an amount of 12.5 to 200 mg/m2. Without using unstable compound such as organic peroxide, the packing container, even when hot-filled with a content, assures very improved content fall-down performance when inverted.

Abstract: 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.

Abstract: Laser marking is surely conducted on the second and subsequent layers of a structural body with a multilayer structure, whereby a marked part can be prevented from being marred, fouled, falsified or erased, as well as marking can be conducted in a variety of colors. A structural body 10 including an inner layer 12 and an outer layer 11 stacked, wherein said inner layer 12 is formed of a resin which does not transmit light with a specific wavelength and said outer layer 11 is formed of a resin which transmits light with the specific wavelength, and a fine periodic structure 14 in the form of convexes and concaves formed by generation of photodecomposition is provided on at least part of the surfaces 13 of the inner layer 12 which is opposite to the outer layer 11.

Abstract: 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.

Abstract: 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.
