Abstract
An adhesive tape or an adhesive label each of which comprises a substrate including a biodegradable polymer layer and an adhesive layer provided on at least one surface of the substrate. The adhesive tape has a release agent layer formed on an opposite surface to the surface where the adhesive layer is provided, or has a release tape which is in contact with the adhesive layer, and the adhesive tape was wound up around a core for storage. The adhesive label has a release sheet which is in contact with the adhesive layer. In such biodegradable adhesive tape and biodegradable adhesive label, a biodegradable polymer is used as a material of the substrate, and therefore the tape and label do not disrupt the natural environment or do not largely disorganize the ecosystem in the soil even when discarded in the soil after use.
