To provide a laminated body with excellent gas barrier properties, moistureproof properties, aroma holding properties, etc., and with excellent sealing properties when it is used for a packaging bag and with which the packaging bag with excellent appearance can be obtained.
When the laminated body with a layer constitution consisting of a polypropylene(PP) layer/an adhesive resin layer/a layer of a saponified substance (EVOH) of an ethylene-vinyl acetate copolymer/an adhesive resin layer/a heat seal layer is prepared, after the saponified substance (EVOH) of the ethylene-vinyl acetate copolymer and the adhesive layer are co-extruded on one surface of the polypropylene(PP) layer to obtain a multi-layered sheet with the layer constitution consisting of the polypropylene(PP) layer/the adhesive resin layer/the layer of the saponified substance (EVOH) of the ethylene-vinyl acetate copolymer/the adhesive resin layer, the multi-layered sheet is drawn in the extrusion direction (MD direction) and in the width direction (TD direction) and in addition, the heat seal layer is laminated on the surface of the adhesive resin layer.
