摘要： A packaging bag for microwave oven heating, is manufactured by using a complex film at least one side of which comprises a sealant layer, folding the complex film or placing the complex films one upon another so as to encounter the sealant layers to each other, sealing the peripheral of the overlapped complex films by a main seal part to form a sealed bag, and providing in the bag a region which is isolated from a space for storing contents by a steam port seal part. The steam port seal part surrounds a steam easy permeable element. The lamination strength between the layers of the complex film in hot condition is not less than 1.5 N/15 mm in width, and the seal strength at least at the steam port seal part in hot condition is not more than 28 N/15 mm in width.

摘要： The present invention provides a food packaging bag, which can hermetically seal and pack foods therein for long-term storage of the foods and can realize cooking in a safe manner, a food-packaged body, and a method for manufacturing the food-packaged body. Preferably, the present invention provides a food packaging bag, which, in a food packed state, does not undergo breakage of the seal upon exposure to pressure or impact applied during transport or storage and, at the time of serving, even when placed in the hermetically sealed state in a microwave oven followed by heating, can automatically lower the internal pressure to prevent the burst of the bag, and a food-packaged body, and a method for manufacturing the food-packaged body. The food-packaged body consists essentially of: a food packaging bag formed of a laminated film comprising at least a base layer and a sealant layer, the sealant layer being located on the interior side of the packaging bag, the packaging bag having therewithin a point seal part connected to or independently of its edge, the point seal part having in its inside an easy-vapor-passing part; and a food which has been packed and hermetically sealed in the packaging bag.

摘要： A packaging material is composed of a heat resistant base layer, a sealant layer, and a resin layer disposed at least a portion between the heat-resistant base layer and the sealant layer. The resin layer is composed of a resin material having a predetermined strength in a non-heated temperature state of less than a room temperature and this strength is lowered in a high temperature state heated, for example, by a microwave oven. Such packaging material can be effectively utilized for many kinds of packaging bags or containers with the sealant layer being disposed to the inner content side of the bag or container.
