Tightly covered container

摘要

A bowl-type container (10a) wherein a coating film (12) comprising a biodegradable plastic as the main component and having at least hydrophobic nature is bonded to the surface of a container body (11a) comprising starch as the main component. The container body is produced by moulding a water-containing material in the form of a slurry or a dough by steam-expansion and can exhibit a highly favourable biodegradability.
