Abstract
A multi-layer biaxially stretched blow bottle having a 3-layer structure of PET/nylon MXD6/PET or a 5-layer structure of PET/nylon MXD6/PET/nylon MXD6/PET, wherein the oxygen gas transmission coefficient of the nylon MXD6 layer is at most 6.0×10−14 cm3·cm/cm2·sec·cmHg as measured under conditions of a temperature of 23° C. and a relative humidity of 80%, and a production process of the bottle by biaxial stretch blow molding at a low stretching temperature and high draw ratios.
