【International Publication】 2005-02-03 WO2005/009869 [Abstract] The purpose of the present invention is to provide a method that can use microwave oven to heat cooking, can also make the internal pressure of the package escape, and will not pollute the inside of the bag. In addition to the steam function of the packaging bag and the use of its packaging. Therefore, the two inner and outer body films (2, 3) having the sealant layer (2s, 3s) are opposed to each other with the sealant layer on the inner side, and have side seal portions (5) and bottom seal portions (4). In the formed packaging bag (1), the outer main body film (2) is folded over the entire width of the bag in the vicinity of the bottom sealing portion (4) in parallel with the bottom sealing portion to form a folded portion (8). An inlet (8) is provided with a degassing opening (11), and an easy peeling tape (12) covering the degassing opening (11) is arranged on the inside of the folding-in part (8) so as to be parallel to the folding-in part (8). The bag is placed in a horizontal width and heat-sealed.
【Sovereignty Items】 1. A packaging bag having a vapor-removing function, in which two inner and outer body films each having a sealant layer are overlapped with the sealant layer on the inner side, and the three sides are sealed to provide a bottom seal. The portion and the side seal portion open between the predetermined portions of the top seal, and the bag is characterized in that a folding portion is formed on the outer main body film, and the folding portion is in the vicinity of the bottom sealing portion and across the entire width of the bag. The outer main body film is folded into a Z-shape in parallel with the above-mentioned bottom seal portion, and the inner-plate portion is formed so as to face the outer-plate portion; the above-described folding-in portion has a steam removing opening; inside the folding-in portion, it is parallel to the folding-in portion. An easy-peel tape having easy peelability is provided on the ground across the width of the bag, and a seal-locking portion is provided on which the easily peelable surface of the easy-peel tape is located on the inner panel surface side of the tuck portion. The heat sealing is performed; the easily peelable surface of the seal blocking portion that peels easily and the sealant layer of the inner panel surface is heat-welded and the easily peelable seal portion that is peelable is located around the steam removing opening.
