Abstract: A biodegradable resin bottle having a container wall (1) including a biodegradable resin and having a vacuum-evaporated film (3) formed on the inner surface of the container wall (1) by a plasma CVD method. The vacuum-evaporated film (3) includes a first hydrocarbon vacuum-evaporated layer (3a) positioned on the inner surface of the container wall and a second hydrocarbon vacuum-evaporated layer (3b) formed on the above hydrocarbon vacuum-evaporated layer (3a). The first hydrocarbon vacuum-evaporated layer (3a) has polar groups introduced therein. The second hydrocarbon vacuum-evaporated layer (3b) exhibits hydrocarbon peaks stemming from CH, CH2 and CH3 in a region of wave numbers of 3200 to 2600 cm?1 as measured by FT-IR, has a CH2 ratio of not larger than 35% and a CH3 ratio of not smaller than 40% per the sum of CH, CH2 and CH3 calculated from the hydrocarbon peaks, and has no polar group introduced therein.

Abstract: A plastic formed article comprising a plastic substrate and a vapor deposited film formed on the surface of the plastic substrate by a plasma CVD method, wherein the vapor deposited film includes an organometal vapor deposited layer having an element ratio C/Si of 2.5 to 13 and an element ratio O/M of not larger than 0.5, and a hydrocarbon vapor deposited layer; and the hydrocarbon vapor deposited layer has a thickness in a range of 40 to 180 nm, exhibits peaks stemming from CH, CH2 and CH3 over a region of wave numbers of 3200 to 2600 cm?1 as measured by FT-IR, and has a CH2 ratio of not larger than 35% and a CH3 ratio of not less than 40%. A film is deposited on a plastic formed article without deteriorated by oxidation, without thermally deformed or without thermally deteriorated not only when PET or polyolefin is used but also when polylactic acid is used as the plastic substrate.

Abstract: A stretch mold container of the present invention is obtained by draw-forming a resin composition containing a poly-L-lactic acid (A) and a poly-D-lactic acid (B) at a molar ratio A:B in a range of 95:5 to 60:40, and has an amount of heat shrinkage of 5.0% or less under heat treatment conditions of 65° C.×24 hours. Despite of being made from the polylactic acids, the stretch mold container exhibits excellent heat resistance.

Abstract: A blow molding multilayered resin container used for holding contents containing an oxidation dye which comprises a moisture barrier layer having a water vapor transmission rate of 0.4 g·mm/(m2·d) or lower and an oxygen barrier layer having an oxygen transmission rate of 10 cm3·mm/(m2·d·MPa) or lower, the oxygen barrier layer being closer to the outside of the container than the moisture barrier layer.

Abstract: A resin composition comprising a saturated polyester resin consisting chiefly of a hydroxyalkanoate unit, a heat-moldable hydroxyl group-containing resin having a vinyl alcohol unit, and an alkaline earth metal carbonate, a molded article composed of this resin composition and, particularly, a container and a multi-layer plastic container having an outer layer formed of this resin composition and an inner layer of a resin consisting chiefly of an ethylene-vinyl alcohol copolymer. The resin composition and the molded articles thereof exhibit not only excellent mechanical properties but also excellent bio-disintegrating property.

Abstract: In a method of producing a metallic container by subjecting a metallic material having an organic resin coating to single-staged or multiple-staged drawing, uniformly coating a lubricant on the surface of the organic resin coating of the metallic material and draw-forming the coated material, according to the present invention, a high lubricating property is obtained at the time of drawing by using a small amount of a saturated hydrocarbon as the lubricant, and by simply heating the formed can, a major portion of the lubricant can be removed and the degreasing and washing steps or the subsequent drying step essential in the conventional method, can be omitted, with the result that the printability or the flavor-retaining property can be markedly improved, and consumption of water resource and energy resource can be reduced and a high effect of preventing environmental pollution can be attained.
