<p>Disclosed is a multilayered container having an intermediate layer comprising an oxygen-absorbable barrier resin composition showing excellent processability upon molding. Specifically disclosed is a multilayered container which comprises an inner layer and an outer layer each comprising an olefin resin and an intermediate layer provided between the inner layer and the outer layer and comprising an oxygen-absorbable barrier resin composition, wherein the oxygen-absorbable barrier resin composition has a cooling crystallization peak temperature lower than that of a base resin (an oxygen barrier resin) which constitutes the oxygen-absorbable barrier resin composition, the multilayered container is formed by a solid-phase molding process at a temperature lower by 1 to 15‹ than the cooling crystallization starting temperature (Tc2) of the base resin, and the body of the container shows a calorific value of less than 0.5 J/g by the isothermal crystallization after heating from 30‹C to 130‹C at a heating rate of 100‹C/min in a thermal analysis of the body. ® KIPO & WIPO 2009</p> |
