Abstract of the Disclosure A molded container having a wall composed of a thermoplastic resin oriented in at least one direction on the wall face, wherein the container wall has a layer of a blend composed mainly of a plurality of melt- extrudable thermoplastic resins, each of which has a solubility parameter ( Sp ) of at least 9.5, at east one of said thermoplastic resins has an oxygen permeabi- lity lower than 5 X 10-11 cc.cm/cm2.sec.cmHg, said thermoplastic resins are chosen so that the difference ( .DELTA.Sp ) of the solubility parameter in said thermoplastic resins is not greater than 4.5. the elongation of said - 1 - resin blend is higher than the arithmetic mean ( ? ) of elongations of the respective thermoplsatic resins, and wherein the container has a thermal shrinkability ( .delta. ) of at least 5 % in the orientation direction of said container wall. - 1'-
