To provide a rice bag which is hardly broken even when deformation and expansion are generated in the rice bag and is excellent in gas permeability, as the rice bag used generally is mainly made of a plastic film, but this rice bag made of the plastic film lacks gas permeability because of the quality of the material, and in addition, when rice is filled into this rice bag to raise the rice bag for transportation, deformation and expansion are generated in the rice bag and becomes easy to break.
The rice bag for storing the rice is made of the plastic film. The rice bag is provided with needling holes 3 and 4 each within a range of a radius R around a corner C as a center on four corners of the rice bag 1 to facilitate to vent air after filling the rice even when the bag is vertically or horizontally laid down under a condition that the rice is filled, and the radius R is set within 25% of the width W of the bag.
