The present invention relates to a biodegradable film for advertisement. In the present invention, films, to which the biodegradable polymer is applied as a cover layer having excellent printability with respect to various solvent inks or bio inks, are used as materials for indoor or outdoor advertisement, such as banners and flexes. Therefore, the present invention can provide environment-friendly biodegradable materials for advertisement, which do not discharge harmful substances during incineration, and can be easily decomposed on landfill treatments.
