Multilayered container and method for producing same

A multilayer container comprising a polyester layer comprising a thermoplastic polyester resin (X) and a polyamide layer comprising a polyamide resin (Y),

• wherein the polyester layer is an innermost layer and the polyamide layer is an interlayer,
• and the polyamide resin (Y) comprises a polyamide resin (Y-1) comprising a structural unit derived from a diamine and a structural unit derived from a dicarboxylic acid, 70 mol % or more of the structural unit derived from a diamine being a structural unit derived from xylylenediamine;
• and 70 mol % or more of the structural unit derived from a dicarboxylic acid being a structural unit derived from an α, ω-linear aliphatic dicarboxylic acid having 4 to 20 carbon atoms, and
• wherein a stretching ratio in a transverse direction (TD) is 2.2 times or more, and a stretching ratio in a machine direction (MD) to the stretching ratio in the transverse direction (TD) (MD/TD) is 0.6 or more and less than 1.0, and
• wherein the multilayer container has a capacity of 200 to 350 mL,
• wherein the multilayer container has a three-layer structure of a polyester layer as an innermost layer and an outermost layer and a polyamide layer as an interlayer, and
• wherein, when the total thickness of the multilayer container is taken as 100%, the polyamide layer is at a position 5.5 to 20% from the inner surface of the multilayer container.
