COC/COP has excellent heat resistance and moisture barrier properties that are being eyed in particular for chemical container usage. As these materials will produce stress easily, they need to be molded by AOKI one-step blow molding technology, in order to realize stable production of containers. In recent years, Aoki has also made great efforts to develop the product molding of HDPE raw materials, and HDPE using AOKI one-step injection stretching and blowing technology will be demonstrated for the first time in this CHINAPLAS.
