PRINTED BIODEGRADABLE PLASTIC FILM

摘要

A printed part (5) is formed on at least one side of a biodegradable plastic film (1). Unprinted parts (7) are distributed substantially uniformly on the inside of the part (5). Lowering of biodegradation rate due to print ink can be avoided while retaining good appearance of a print by adjusting the shape, distribution, and the area ratio of the unprinted parts appropriately.
