Abstract

ECOZEN®T110 (EZT), as a bio-based polyester has been used to improve the glass transition temperature (T_g) and thermal shape stability of polyethylene terephthalate (PET). In this study, the applicability of PET/EZT blends for manufacturing hot-filling bottles using an injection stretch blow molding machine in a conventional process was evaluated. A fully miscible blend (single T_g) was observed in 10 % EZT, despite the homogeneous phase being maintained in all other EZT ratios (30 %, 50 %, and 70 %). The addition of EZT led to an increase in the T_g and the transparency of the bottles, and maintains their original shape after the hot-filling tests. High T_g bottles with a low melting point and crystallinity were obtained, circumventing the need for complex equipment and time-consuming processes that are otherwise required for conventional PET bottles. Therefore, the PET/EZT blends can be used as an alternative material to manufacture hot-filling bottles using conventional bottle processing.
