Estimating the term…
A stretch-blow-formed polyester container having an average thickness of not more than 280 μm in the body portion thereof, and effectively suppressing the deformation that is caused when the container is filled with a content of a high temperature, wherein in the measurement of dynamic viscoelastic properties in an axial direction at a central portion of said body portion, a tan δ peak value and a tan δ peak temperature at the peak value satisfy either; (i) the tan δ peak value is in a range of 0.23 to 0.29, and the tan δ peak temperature at the peak value is in a range of 111 to 118° C.δ; or (ii) the tan δ peak value is in a range of less than 0.25, and the tan δ peak temperature at the peak value is in a range of not lower than 119° C.
A stretch-blow-formed polyester container having an average thickness in a body portion of not more than 280 μm, wherein in a measurement of dynamic viscoelastic properties in an axial direction at a central portion of said body portion, a tan δ peak value is 0.23 to 0.29, and a tan δ peak temperature at said peak value is 111 to 118° C.
