Zusammenfassung:	To provide a packaging bag for a microwave oven which is excellent in steam-passing stability with an improved sealant layer.SOLUTION: A packaging bag for a microwave oven includes: a base material layer; a sealant layer; and a release varnish layer formed partially between the base material layer and the sealant layer. The sealant layer is made of a polyolefin resin film having heat-sealing property. The film has low-breaking-point ductility in a flow direction of the film at heating temperature of a microwave oven.SELECTED DRAWING: Figure 1 【課題】シーラント層の改良により蒸通安定性に優れた電子レンジ用包装袋を提供する。【解決手段】基材層と、シーラント層と、前記基材層及び前記シーラント層の間に部分的に形成された剥離ニス層と、を備え、シーラント層が、ヒートシール性を有するポリオレフィン樹脂のフィルムからなり、当該フィルムの流れ方向の破断点伸度が、電子レンジの加熱温度において低い。【選択図】図１
