Abstract

Provided are a resin composition having excellent oxygen barrier property under high humidity as a novel resin material, a molded body, a method for producing a molded body, and a method for producing a pellet using the resin composition. The resin composition includes a resin component and a plate-shaped talc having an aspect ratio of more than 18, 80 mass % of the resin component comprising a barrier resin having an oxygen transmission coefficient of 5.0 cc·mm/(m·day·atm) or less as measured according to ASTM D3985 at a relative humidity of 60% and a temperature of 23° C., and a content of the plate-shaped talc being from 3.0 to 55.0 mass % when a total of the barrier resin and the plate-shaped talc is 100 mass %.
