<P>PROBLEM TO BE SOLVED: To provide a packaging bag for heating in a microwave oven in which a liquid and a solid containing much water are divided into two chambers and packaged, a packaged body is heated in the microwave oven, the content divided into two chambers and packaged can be cooked in a mixed manner, and steam generated during the cooking can be automatically exhausted outside. <P>SOLUTION: A laminate film with an easily peelable heat-bond resin layer laminated on an inner side thereof is folded, a side end heat-bond part is formed on an edge facing a fold, an end edge heat-bond part is formed on both edges orthogonal to the fold, and a bulkhead heat-bond part is formed parallel to the fold between the fold and the side end heat-bond part to form a rectangular bag demarcated into two chambers A and B. The width of the heat-bond part satisfies the inequalities : width of bulkhead heat-bond part ≤ width of side end heat-bond part < width of end edge heat-bond part. The length between inner ends of both end edge heat-bond parts is larger than the length between inner ends of the fold and the side end heat-bond part. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
