摘要:
A multi-layered biaxial stretch blow molded bottle which has a three-layer structure of PET/nylon MXD6/PET or a five-layer structure of PET/nylon MXD6/PET/nylon MXD6/PET, and exhibits a permeation coefficient for an oxygen gas of the nylon MXD6 layer of 6.0 X 10-14 cm3·cm/cm2·sec·cmHg or less, as measured under a condition of a temperature of 23°C and a relative humidity of 80 %; and a method for producing said bottle which comprises employing a biaxial stretch blow molding using a low stretching temperature and a high stretch ratio.
