A method of manufacturing a composite container. The method includes providing a paper label, and a preform; providing a molding die equipped with a closed, cylindrical lower mold and an upper mold composed of a plurality of split-mold segments; arranging the paper label in the lower mold; arranging the preform between opened split-mold segments; moving one or both of the lower mold with the paper label and the upper mold with the preform in a direction towards each other to close the molding die; implementing blow-molding on the preform in the molding die; and opening the molding die to release the composite container.
