PURPOSE:To use suitably a plastic container particularly as a food packaging container by manufacturing the plastic container having transparency, superior barrier properties against water vapor and against UV rays. CONSTITUTION:A peform composed of at least two layers consisting of a thermoplastic polyester layer (layer A) containing 1mol% or more to less than 80mol% of etylene naphthalate unit as repeating unit and a polyolefin layer (layer B) is injected and molded, and further stretch-blown at least in an monoaxial direction in a temperature range of 110 deg.C-140 deg.C to manufacture a multi-layer plastic container.
