Abstract
[Problem] To provide a polylactic acid bottle having a vacuum-evaporated film on the inner surface of the bottle wall, effectively preventing the thermal deformation of the bottle at the time of forming the film and exhibiting excellent barrier property against oxygen and water. [Means for Solution] A biodegradable resin bottle has a wall formed by a biodegradable resin and a vacuum-evaporated film on an inner surface of the wall by a plasma CVD method, and wherein said vapor-evaporated film exhibits hydrocarbon peaks stemming from CH, CHand CHin a region of a wave number of 3200 to 2600 cmas measured by FT-IR, and per the sum of CH, CHand CHcalculated from the hydrocarbon peaks, a CHratio is not larger than 35% and a CHratio is not smaller than 40%.
