In producing a laminated packaging material comprising a base film, a silicon oxide layer and a sealant layer that are laminated together, the sealant layer is formed by laminating thermoplastic resin on the silicon oxide layer in thickness of less than 30 µm by using an extrusion coating method. At this time, in addition to the thermoplastic resin layer formed by extrusion coating method, thermoplastic resin film of another type may be laminated on the outside of the thermoplastic resin layer so that the two thermoplastic resin layers form the sealant layer. In this case, sandwich lamination is adopted in which thermoplastic resin is extruded into between the silicon oxide layer and the thermoplastic resin film in thickness of less than 30 µm. In addition, in a laminated packaging material for vertical pillow type packaging, consisting of a laminate of the sealant layer, the base film and the silicon oxide layer, a thermoplastic resin layer and an outer basic material are laminated on the outside of the silicon oxide layer simultaneously with the formation of the thermoplastic resin layer by extruding the thermoplastic resin between the outer basic material and the silicon oxide layer.
