Abstract: The present invention discloses a hot drawn multilayered structure comprising a layer of an ethylene-vinyl alcohol copolymer composition comprising 70 to 95 wt% of EVOH having an ethylene content of 25 to 60 mol% and a saponification degree of at least 90% and, 5 to 30 wt% of an aliphatic copolymer polyamide containing capramide as a main structural unit, having a ratio of the number of methylene groups to the number of amide groups satisfying the equation: 6.6 ? CH2/NHCO ? 10 having a melting point of 110 to 180°C and showing a melt index of 0.1 to 10 g/10 mins., having provided a thermo- plastic resin layer onto at least one surface of said layer. The multilayered structure of the present invention has excellent gas barrier properties and minimized unevenness in gas barrier properties caused by different measurement areas but hardly contains gel, hard spots, etc. - 1 -
