The present invention adheres the aluminum sheet fabric using a hot melt adhesive to the upper surface of the woven laminated sheet fabric supplied while supplying the aluminum sheet fabric and the woven laminated sheet fabric, one end of the aluminum sheet fabric is the woven laminated sheet fabric Sticking in a state that protrudes from one end of the, and the other end of the aluminum sheet fabric is located inside the other end of the woven fabric sheet fabric; Forming the aluminum sheet fabric and the woven laminated sheet fabric in a turret shape; Applying a polyethylene adhesive to the other end of the aluminum sheet fabric and the upper surface of the other end of the woven laminated sheet fabric; Cutting the aluminum sheet fabric and the woven laminated sheet fabric to which both ends are adhered so that an upstream end and a downstream end are formed; And heat sealing the upstream end or downstream end of the cut aluminum sheet fabric and the woven laminated sheet fabric, thereby sealing the aluminum sheet fabric to an aluminum sheet and an upper surface and a lower surface of the aluminum sheet. It is made of a film, the film has a polyethylene material, the aluminum sheet and the film is bonded by a urethane-based curable adhesive and polyethylene resin, the woven laminated sheet fabric is made of paper and woven sheet, the woven The sheet has a polyethylene material, the paper and the woven sheet are adhered by a polyethylene adhesive, a hot melt adhesive is adhered to the upper surface of the woven laminated sheet fabric, and the aluminum sheet fabric and the outer woven laminate are coated with the polyethylene adhesive. Sheet fabric is glued at the same time, so adhesive Provided is a method of manufacturing a double-structured bag, which is characterized in that the process of applying a simplification, and an apparatus for manufacturing a double-structured bag using the same. Therefore, after forming the aluminum sheet fabric which is the inner skin and the woven fabric sheet fabric which is the outer skin in a bag shape, by simultaneously bonding the inner skin and the outer skin using polyethylene, the adhesion process can be simplified to improve productivity.
