<p>A biaxially stretched blow-molded container having a layer made of a trimethylene-naphthalate-based polyester resin, wherein at least a container barrel part of the trimethylene-naphthalate-based polyester resin layer satisfies either or both of the following: (i) in DSC, the layer has a calorific value, Tc1, of 10 J/g or lower; and (ii) in dynamic viscoelasticity analysis, the layer has a tanH maximum temperature of 90°C or higher and a tanH maximum of 0.4 or less. The biaxially stretched blow-molded container can effectively have the excellent gas-barrier properties inherent in the trimethylene-naphthalate-based polyester resin.</p> |
