To provide a laminate with which a packaging bag having excellent gas barrier properties, moistureproofness, perfume retentivity and the like, having excellent sealability and excellent appearance when the bag is formed can the obtained, and a method for manufacturing the same.
The method for manufacturing the laminate having a laminar constitution of a polypropylene(PP) layer, an adhesive resin layer, a saponified ethylene vinyl acetate copolymer (EVOH) layer, an adhesive resin layer and a heat sealing layer comprises the steps of co-extruding a polypropylene(PP) and an adhesive resin to obtain a multilayer sheet having a laminar constitution of the polypropylene(PP) and the adhesive resin, then stretching the multilayer sheet at least in an extruding direction (direction MD), then sequentially co- extruding the saponified ethylene vinyl acetate copolymer (EVOH) and the adhesive resin on a surface of the adhesive resin, then stretching the sheet in a lateral direction (direction TD), and further laminating a heat sealing layer on the surface of the adhesive resin layer.
