<p>PROBLEM TO BE SOLVED: To provide a method for efficiently manufacturing a package in which the purity of charged gas is high even when the stiffness of a laminated body constituting an outer bag is high, in manufacturing a package in which gas is charged in an intermediate part of a packaging container made of a double bag.SOLUTION: In a method for manufacturing a package in which a content is stored in an inner bag of a packaging container composed of the inner bag 2 having permeability for intended gas and an outer bag 3 having no gas permeability, and gas is charged between the inner bag and the outer bag forming a gas storage part 22, after the periphery of a gas charging port 8 provided at one end part of the gas storage part is heated and softened, gas is blown from the gas charging port, and air and part of the gas in the gas storage part are discharged from a gas discharging port 9 provided at the other end part of the gas storage part. After the gas discharging port is closed, the gas discharging port and the gas charging port are sealed tightly.</p> |
