2. Description of the Related Art Conventionally, as a take-out container for food such as dumplings and pork dumplings, a paper container with a lid made of a laminated body having an aluminum foil laminated on the inner surface of a paperboard has been used. Since aluminum foil is laminated on the inner surface, it has excellent water resistance and oil resistance, and there is no fluffing of paperboard or exudation of oil content due to moisture, but since the aluminum foil is laminated on the container, the contents are packed. It was inconvenient that I could not heat it in the microwave as it was and had to transfer it to another container and heat it. Further, since aluminum foil is used, the container is expensive, and waste pollution becomes a problem when it is discarded.
