A method and apparatus for charging the gas compartment portion of a bag () in which incisions () are formed in gas introduction section () of the gas compartment portion (). A pair of gas injection nozzles () are disposed so as to be on the opposite sides of the bag and reciprocate between its standby and advanced positions, so that in the advanced position, the discharge outlets () of the gas injection nozzles are aligned with the gas introduction section on both sides, and compressed gas is injected into the gas introduction section through the incisions. A small gap (L) is provided between the discharge outlets of the gas injection nozzles when they are in the advanced position. As the gas is injected, film sheets of the expanded gas introduction section closely adhere to the discharge outlets, so that the gas injection state becomes stable.
