摘要： A method for manufacturing a container includes forming a top portion of a preform by injecting a first material into a mold. A bottom portion of the preform is formed by injecting a second material into the mold to form inner and outer layers of the bottom portion and injecting a third material into the mold to form an intermediate layer of the bottom portion that is positioned between the inner layer and the outer layer. The third material includes virgin polyethylene terephthalate and an additive.
