Beschreibung
Zusammenfassung:	This invention provides a multilayered structure comprising a layer of an ethylene-vinyl alcohol copolymer composition having specific flow characteristics in the relationship between the heating time and the extrusion rate measured with a capillary rheometer (Koka Flow Tester), and a hydrophobic thermoplastic resin layer. From the multilayered structure according to the present invention, molded articles having a multilayered structure and having an excellent appearance can be obtained; more particularly, in a continuous melt molding operation over a long period, a molded article having a multilayered structure and having an excellent appearance can always be obtained without worsening the appearance with running time.
