The disclosure relates to a laminated, web-shaped packaging material intended for packaging containers in which the longitudinal joint has improved gas-and liquid-tightness properties and is substantially planar. The laminated, web-shaped packaging material includes a core layer and a layer of metal or metal oxide applied on one side of the core layer, and is processed along the longitudinal edges of the web in such a manner that the metal layer is exposed from the core layer along one of the edges and the edges are then covered with outer layers of plastic.
