Abstract: The present invention relates to a packaging bag composed of a multilayer film and having a steam releasing mechanism. The multilayer film has at least a base layer and a welding layer and has a moisture content of not more than 1.0% in a state in which the packaging bag is filled with a content. The steam releasing mechanism has at least a steam releasing portion formed to have a maximal width of 3 to 20 mm. The internal pressure of the packaging bag is kept to be not more than 115 kPa during a period from the time the internal pressure is released through the steam releasing portion as a result of an increase in the internal pressure caused by heating in a microwave oven to the time the heating in the microwave oven finishes. This can prevent breakage of the bag or leakage of the content due to the increase of the internal pressure by the heating, and reduces or prevents effectively thermal damage irrespective of properties of the content.
