<p>PROBLEM TO BE SOLVED: To improve appearance, see-through, impact delamination resistance and the like, by constituting a multi-layer container of two kinds of saponification products of an ethylene-vinyl acetate copolymer and a resin composition layer which satisfies specific conditions and another thermoplastic resin layer. SOLUTION: The multi-layer container is constituted of two kinds of EVOH (a saponification product of an ethylene-vinyl acetate copolymer) obtained by copolymerizing ethylene unsaturated monomers such as olefins e.g. propylene, 1-butene and isobutene and unsaturated acids e.g. acrylic acid and methacrylic acid. In addition, the container comprises thermoplastic resin layers which have the potassium content (ppm) <=300 and >=5 of resin composition, the sodium content (ppm) <=300 and >=5 of resin composition and the phosphorus content (ppm) <=200 and <=5 of resin composition respectively.</p> |
