Abstract:
A biaxially stretched polyester bottle of which a central part of a bottle body portion satisfies at least either (1) that an elongation in the circumferential direction is larger than an elongation in the longitudinal direction in the tensile test at room temperature or (2) that an orientation parameter in the circumferential direction is smaller than an orientation parameter in the longitudinal direction in the Raman spectrometry. Despite the body portion having an average thickness as small as 250 μm or less, the bottle has a drop impact resistance while exhibiting excellent appearance.
