<p>PROBLEM TO BE SOLVED: To obtain a double-side self-adhesive laminate not destructing natural environment and not disturbing an ecosystem in soil even if discarded into soil, and to seal a bag mouth in a freely openable and closable manner. SOLUTION: A double-side self-adhesive laminate 10 is obtained by forming a strong self-adhesive layer 2 on the single surface of a biodegradable base material 1 and forming a weak self-adhesive layer 3 to the other single surface thereof. In this case, it is pref. to form a non-self-adhesive part 4 on a part of the surface of the weak self-adhesive layer 3. Further, the biodegradable base material 1 is pref. formed from a biodegradable polymer.</p> |
