MULTILAYERED STRUCTURE AND PRODUCTION OF CONTAINER THEREOF

摘要

PURPOSE:To easily obtain a multilayered structure having barrier properties without damaging the excellent moldability of a styrenic resin too much by combining an ethylene/vinyl alcohol copolymer, an adhesive resin and a styrenic resin to laminate them. CONSTITUTION:A multilayered structure is obtained by combining an ethylene/ vinyl alcohol copolymer, an adhesive resin and a styrenic resin to laminate them. In the ethylene/vinyl alcohol copolymer, the occupying ratio of an integrated value from the low temp. side of a heating process DSC peak to 160 deg.C with respect to the integrated value of the whole of peaks is set to 30%. By this constitution, a multilayered structure container extremely high in oxygen barrier properties and suitable for the preservation of food can be efficiently produced in low percent defective and low cost.
