SYNTHETIC RESIN MADE BLOW CONTAINER

摘要

PROBLEM TO BE SOLVED: To provide a synthetic resin made blow container low in shape deformation and contraction and excellent in heat resistance even when it is used under high temperature environment. SOLUTION: In the synthetic resin made blow container manufactured by performing an axial stretching blow molding at one time before and after heating and shrinking process for removing residual stress, and the container has a density change rate of -0.03% or more in relation to a blow intermediate body 2 after a heating process.
