Multilayered container

A method of forming a multilayered container made of a flange portion, a body portion and a bottom portion comprising:

• providing an inner layer comprising an olefin resin;
• providing an outer layer comprising an olefin resin;
• blending an oxidizable polymer having unsaturated ethylenic bonds with a base resin to form an oxygen-absorbing barrier resin composition;
• providing an intermediate layer between the inner layer and the outer layer, wherein said intermediate layer consists of said oxygen-absorbing barrier resin composition;
• and
• forming a solid-phase multilayered container by using a plug assisted vacuum-pressure forming machine in a temperature range which is 148 to 159° C.;
• wherein the olefin resin is selected from the group consisting of polypropylene (PP), an ethylene-propylene copolymer, and a blend thereof;
• wherein the base resin is an ethylene-vinyl alcohol copolymer resin;
• wherein a cooling crystallization peak temperature of the oxygen-absorbing barrier resin composition is lower than that of the base resin (an oxygen barrier resin) of the oxygen-absorbing barrier resin composition;
• wherein a thermal analysis of a body portion of the container shows that an amount of heat released during isothermal crystallization after a temperature raise from 30° C. to 130° C. at 100° C./min and held for 30 minutes is less than 0.5 J/g;
• and
• wherein x-ray diffraction measurement shows that an intensity ratio I/I0 of an intensity (I) of an (110) plane to a baseline (I0) is 4 to 10 in at least the body portion of the container.
