摘要： An injection-molded preform for manufacturing plastic containers, for example plastic bottles, in a stretch blow molding process is disclosed. The preform can have an essentially elongated preform body, whose one longitudinal end is formed closed. On an opposite longitudinal end, the preform body is connected to a neck section that is provided with a pour opening and whose outer wall has a connector to make an interlocking connection with a closure that is equipped with corresponding engagement. The neck section has at least one constriction that extends all the way around and has a wall thickness of between 0.4 mm and 0.8 mm. The injection-molded plastic material exists at least on the at least one constriction in a state that is highly oriented and at least partially crystalline, due to an injection-molding process.
