    Abstract: PURPOSE:To improve the barrier performance against gas such as oxygen, carbon dioxide, or the like, and water vapor by forming a multilayer vessel comprising at least two layers of thermoplastic polyester having a specified composition and polyolefin. CONSTITUTION:A perform is molded by injection molding, which comprises at least two layers of a thermoplastic layer containing an ethylene naphthalate unit of 80mol% as a repeated unit and a polyolefinic layer. It is then subjected to draw/blow molding in at least single axis direction at a temperature of 110-170 deg.C, to thereby form a multilayer vessel. The used polyolefin preferably contains a propylene unit of 70mol% as a repeated unit, and also may be a copolymer of olefin such as 1-octane of 30mol%. In order to enhance the transparency, and the barrier performance against gas such as oxygen, carbon dioxide or the like in the vessel, it is preferable to effect the draw-molding in at least a single axis direction.

    Abstract: PURPOSE:To obtain a multilayer plastic container having transparency and excellent in barrier properties to gas, water vapor and ultraviolet rays by forming the container consisting of two layers of a thermoplastic polyester layer which has ethylene terephthalate as a main repeating unit, and a thermoplastic polyester layer containing ethylene naphthalate. CONSTITUTION:In this process for producing a multilayer plastic container, a preform (preliminarily molded article) consisting of at least two layers of a thermoplastic polyester layer (layer A) which has the main repeating unit of 90mol% or more ethylene terephthalate as a repeating unit, and a thermoplastic polyester layer (layer B) which has 5-90mol% ethylene naphthalate as a repeating terminal, is molded by injection molding and then blow-molded to be oriented at least in an uniaxial direction in a temperature range of 80-120 deg.C. The multilayer plastic container thus produced is uniform in its thickness, has transparency and is further excellent in barrier properties to gas, such as an oxygen gas and a carbonic acid gas, or to water vapor, and also in barrier properties to ultraviolet rays. In particular, the container can be suitably utilized as a foodstuff packaging container.
