PROBLEM TO BE SOLVED: To easily discharge air left in a bag out of the bag when rice and a granular matter are charged into the bag formed of a synthetic resin film, and to prevent foreign objects, insects and water from entering the bag through its discharging port.;SOLUTION: Non-sealed portions are intermittently arranged at a bottom seal section of a bag formed of synthetic resin film and a complete seal is applied in parallel with the intermittent seals in spaced-apart relation from the applied position toward the bottom side by a distance of 5 to 10 mm. A plurality of through-pass holes are formed between the two rails. The air in the bag is discharged out of a clearance between the non-sealed portions into an area between the two rails, the discharged air is discharged out of the bag through a plurality of through-pass holes. Some foreign materials are prevented from entering in an arrangement that the discharging port is formed as a double-layered one by a different structure composed of the non-sealed portions and the through-pass holes.;COPYRIGHT: (C)2009,JPO&INPIT
