Abstract
A sealed packing body comprising a packing body made from a laminated material and a sealing member for sealing the packing body; wherein the laminated material includes a base material layer, a thermoplastic resin layer containing an iron powder, and a thermoplastic resin layer which permits a laser beam to pass through, at least the surface of the sealing member which comes in contact with the packing body comprising a thermoplastic resin which permits the laser beam to pass through; and the surfaces of the packing body and the sealing member coming in contact are sealed together by laser welding. It is, therefore, allowed to effectively utilize the iron powder that has, heretofore, been utilized as an oxygen absorber of the packing containers and to efficiently conduct the laser welding.
