Document Type and Number:
WIPO Patent Application WO/2018/003790
Kind Code:
A1
Abstract:
The present invention relates to a polyester stretch blow-molded container, which is thin-walled with an average body section thickness of 280 µm or less and for which deformation that occurs during high temperature filling of contents is effectively limited, and is characterized in that the tanδ peak value and the tanδ peak temperature at said peak value in dynamic viscoelasticity measurements measured in the axial direction of the center portion of the body section satisfy either (i) tanδ peak value is in the range of 0.23-0.29 and the tanδ peak temperature at said peak value is in the range of 111-118°C, or (ii) tanδ peak value is less than 0.25 and the tanδ peak temperature at said peak value is in the range of 119°C or higher.
