Composite preform, composite container, composite preform, plastic member, and method for producing composite container

A method for producing a composite container, the method comprising the steps of:

• preparing a preform made of a plastic material;
• disposing a plastic member on the outside of the preform, the plastic member having a print region disposed on a surface of the plastic member in advance;
• heating the preform and the plastic member and inserting the preform and the plastic member into a blow molding die;
• and
• integrally inflating the preform and the plastic member by performing blow molding on the preform and the plastic member in the blow molding die,
• wherein the plastic member is not welded or adhered to the preform so that the plastic member can be peeled off from the preform, and
• wherein the plastic member has a function of heat-contracting with respect to the preform.
