Abstract:
[Problem] To provide a composite preform that can ensure that worsening of the appearance of a surface of a plastic member caused by near-infrared heating prior to blow molding is effectively prevented and that an inner preform is efficiently heated.
[Solution] The composite preform of the present invention includes a preform and a heat-contractive plastic member, the preform including a mouth part; a trunk part linked to the mouth part; and a bottom part linked to the trunk part, and the heat-contractive plastic member being disposed so as to surround the outside of the preform and including at least a colored layer that contains a resin material and a colorant, wherein the heat-contractive plastic member has a near-infrared transmittance of 50% or higher.
