12 Claims

1. A molded container comprising a resin layer containing an aliphatic polyester-based resin (A) and a polyvinyl alcohol-based resin (B) as main component resins,

wherein the resin layer has a resin phase-separated structure having a continuous phase comprising the aliphatic polyester-based resin (A) as a main component, and a ribbon-like dispersed phase comprising the polyvinyl alcohol-based resin (B) as a main component,

wherein the aliphatic polyester-based resin (A) and the polyvinyl alcohol-based resin (B) form a sea-island structure, with the polyvinyl alcohol-based resin (B) serving as an island portion and forming the ribbon-like dispersed phase, and

wherein the ribbon-like dispersed phase has an average length (L1) of 6 μm or more and 100 μm or less, an average thickness (L2) of 0.1 μm or more and 5 μm or less, and a ratio of the average length (L1) to the average thickness (L2) (L1/L2) of 5 or more and 100 or less.
