Abstract
As a molded article that has gas barrier properties even if a gas barrier layer is not provided and that also has molding stability and biodegradability, there is proposed a molded article containing an aliphatic polyester-based resin (A) and a polyvinyl alcohol-based resin (B) as main component resins, wherein the molded article has a resin phase-separated structure having a continuous phase including the aliphatic polyester-based resin (A) as a main component, and a ribbon-like dispersed phase including the polyvinyl alcohol-based resin (B) as a main component.
