<p>PURPOSE:To provide a vessel which maintains a good oxygen barrier property and transparency even in the case of humidity bactericide by providing a layered structure of a layer of mixture of poly m-xylylene adipamide and nylon 6 and a resin layer having glass transition point of 110-200 deg.C. CONSTITUTION:A layered structure comprises a layer 13 of mixture of poly m-xylylene adipamide and nylon 6 and a resin layer 11 having glass transition point of 110-200 deg.C, with an adhesive layer 12 being interposed therebetween. Poly m-xylylene adipamide of the layer 13 imparts oxygen barrier property to a vessel to maintain good oxygen barrier property even after humidity heat treatment. And nylon 6 prevents degradation of transparency due to humidity heat treatment. Poly m-xylylene adipamide and nylon 6 are mixed at a weight ratio of 90:10-50:50. The layer 11 has a good quality, in which resins are polycarbonate, polyarylate etc. In order to firmly bond the layer 13 to the layer 11, an adhesive layer 12 is interpose between the layers 11 and 13, in which adhesives for use in dry laminate of urethane etc., is used.</p> |
