Biodegradable composition, processed biodegradable article such as food container, and method of producing the same

摘要

The present invention provides a processed biodegradable article having excellent water resistance and rigidity, which can be used as a food container, and a biodegradable composition required to produce the processed biodegradable article comprising 15-75% by mass starch, 5-50% by mass protein, 3-50% by mass cellulose fiber, 0.5-20% by mass polyphenols such as pyrogallol and gallic acid, and 0-5% by mass sodium chloride.
