<p>PROBLEM TO BE SOLVED: To provide a blow molding method and a composite preform capable of eliminating a need of an application process of a label by a labeler.SOLUTION: A preform 10a made of a plastic material is first prepared. An inner label member 60 is disposed on an outside of the preform 10a, and an outer contraction member 40 at least partially translucent or transparent is disposed on an outside of the inner label member 60. Then, the preform 10a, the inner label member 60 and the outer contraction member 40 are heated to prepare a composite preform 70 having the preform 10a, the inner label member 60 and the outer contraction member 40. Thereafter, the composite preform 70 is inserted into a blow molding metal mold 50, and blow molding is performed to the composite preform 70 inside the blow molding metal mold 50, so that the preform 10a, the inner label member 60 and the outer contraction member 40 in the composite preform 70 are integrally expanded, and a composite container 10A is obtained.</p> |
