This patent relates to a laminated tape-like packaging material. The material has a core and a metal or metal oxide layer laid on one side, the longitudinal edges of the strip are machined so that the metal layer is exposed along the edge from the core, and then the edge is covered by the outer layer of plastic. . Longitudinal edges are chamfered, and the original wider material band can be divided into a plurality of narrower base bands in the longitudinal direction. By tubular and folding-folding of the laminated band material, the longitudinal edges of the material band are sealed together in the longitudinal direction of the tube, so that a packaging container can be made in which the edges of the metal layer exposed from the core layer are folded. Placed on the metal layer on the opposite side of the strip of material.
