    摘要: 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, the ratio of the number of methylene groups to the number of amide groups satisfying the equation: having a melting point of 110 to 180°C and showing a melt index of 0.1 to 10 g/10 min, and a thermoplastic resin layer provided on at least one surface of said layer.
    The multilayered structure of the present invention has excellent and highly uniform gas barrier properties and contains hardly any gel or hard spots.
