Provided is a package, which has a layer wherein an island-sea structure having a small domain diameter and a high domain density is formed without compromising the ability to be molded into a container, and the like, and which has excellent barrier properties and transparency. The package has a mixed layer formed from a mixture of a base resin and a functional resin composition comprising inorganic microparticles. The mixed layer is molded into an island-sea structure wherein the base resin layer forms the continuous phase and the functional resin composition forms the non-continuous phase, and the functional resin composition accounts for 25 to 55% of the cross-sectional surface area. |
