To provide a method for manufacturing a laminated bottle capable of certainly applying decoration to the laminated bottle without largely lowering gas barrier properties caused by an intermediate layer.
A method for manufacturing a laminated bottle includes a primary heating process for heating a bottomed cylindrical preform having an inner layer, an outer layer and the intermediate layer arranged between the inner and outer layers to a stretchable temperature, a primary stretch blow molding process for subjecting the preform to stretch blow molding in a primary mold to form a primary molded product, and a secondary stretch blow molding process for subjecting the primary molded product to stretch blow molding in a secondary mold to form the laminated bottle. Before the primary heating process, a water absorbing process for absorbing moisture in the intermediate layer of the preform is further provided.
