<P>PROBLEM TO BE SOLVED: To provide a bag for microwave oven heating which is capable of unsealing the bag at a predetermined part by steam generated by heating to easily release the steam, and completely sealing to eliminate germ ingress, is uniform in the strength of a heat-sealed part without any weak portion, is free from inconvenience in transport and storage, and is capable of easily controlling the amount and the part for emitting steam. <P>SOLUTION: In the bag 11 for microwave oven heating, a laminate film consisting of an inner layer, an intermediate layer and an outer layer is heat-sealed at a peripheral part so as to join the inner layers with each other, and a heat-seal part 12 is formed. The inner layer of the laminate film is formed of a resin having water resistance and heat-sealability. The intermediate layer is formed of an adhesive material to stick the inner layer to the outer layer. The outer layer is formed of a resin having less water-resistance. A small hole zone 25 consisting of a large number of small holes is formed in the inner layer, and the heat-sealed part 12 overlaps the small hole zone 25 to form an overlapping part 14. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
