PROBLEM TO BE SOLVED: To prevent cooked rice from sticking on and being left in the inside of a bag by heat sealing and closing the side of the bag made of a non-woven fabric having a specific METSUKE, toughness and permeability widthwise and lengthwise and also by forming a bottom. SOLUTION: A non-woven fabric having 30-120/gm<2> METSUKE 100mm or more toughness both widthwise and lengthwise and 300-800cc/cm<2> /sec. permeability is used for forming a cooking bag. This non-woven fabric is heat sealed at heat seal lines 2, 2', 2", 4, 4', and also a bottom is formed by a center folding line 5' and a non-woven fabric crease 6. From this, a bag which is big enough to contain from a medium to a large amount of rice, has appropriate rigidity, allows relatively easy ventilation and is good in permeability can be obtained. As a result, not only delicious rice can be cooked, but the cooked rice is not left sticking on the inside of the bag. Furthermore, it is easy to pour the rice into the bag and also to take out the cooked rice from the bag. |
