PURPOSE: An innovative flexible packaging type, a manufacturing method thereof, and a use of the same are provided to include a different material layer which has hydrolysis stability, thereby providing long service life. CONSTITUTION: One or more adhesive layers are arranged. Two or more different material layers glued by the adhesive layer are included. One or more among the adhesive layers include a carbodiimide or two or more kinds of a carbodiimide mixture. The material layers are comprised of polyethylene terephthalate, polyolefin, polyamide, and aluminum foil. The adhesive layers are comprised of solvent-based, water-based, solvent-excluded, and UV-hardening materials.
