PROBLEM TO BE SOLVED: To provide a packing bag capable of safely smoking food when the food is heated with a microwave oven by dividing the inside thereof into two chambers, entering the food in one-side chamber and entering a smoking constituent in the other-side chamber, in a packing bag having a steam vent function.SOLUTION: This bag for microwave oven heating includes a main food storage part for storing food therein, and a cooking material storage part for storing a cooking material for making main food into a steamed dish or smoked food. The bag for microwave oven heating includes an upper-surface film including a steam permeation hole, a lower-surface film, and an intermediate-layer film arranged between the upper-surface and lower-surface films and having gas permeability, wherein a peripheral fusion bonding part is formed by subjecting three sides of a peripheral part of the upper-surface film to thermal fusion bonding to those of a peripheral part of the lower-surface film, and a sealable mechanism is formed in the other one-side peripheral parts.COPYRIGHT: (C)2013,JPO&INPIT【課題】蒸気抜き機能を有する包装袋において、内部を2室とし、一方の室に食品を入れ、他方の室に燻製成分を入れることによって電子レンジで加熱した時に食品を燻製することが安全に出来る包装袋を提供すること。【解決手段】食品を収容する主食品収容部と主食品を蒸し料理または燻製に作成するための調理材料を収容する調理材料収容部を有する電子レンジ加熱用袋であって、通蒸孔を備えた上面フィルム、及び下面フィルムと、これら上下面フィルム間に配置されたガス透過性を有する中間層フィルムからなり、上面フィルムの周縁部と下面フィルムの周縁部の三方を熱融着することで周縁融着部が形成されており、他の一方の周縁部には封止可能な機構を設けた電子レンジ加熱用袋。【選択図】図1
