ように調理手段に応じて適宜選択すればよい。The internal pressure of the bag body adjusted by the exhaust means varies depending on the food to be contained. For example, in the case of a bag containing meat buns, the internal pressure is set to be close to the conditions when steaming meat buns in a steaming basket. As described above, it may be appropriately selected according to the type of food to be stored in the bag, simple cooking such as heating, steam cooking, and the like.

手段とすることも食品包装用袋の製造上好ましい。Further, the exhaust means for exhausting when the internal pressure of the bag exceeds a predetermined pressure so that the internal pressure of the bag does not exceed a predetermined internal pressure may be a so-called exhaust valve structure capable of maintaining a constant internal pressure. However, it is necessary to use a synthetic resin film that forms the bag body to form a meandering exhaust passage formed by heat-sealing the synthetic resin films for the production of food packaging bags. preferable. Further, when the exhaust means is a tubular body having a meandering exhaust passage formed by heat-sealing synthetic resin films forming a tubular body, the tubular body is formed into a bag of various shapes and sizes. Since the exhaust means can be provided in the bag simply by attaching it, it is also preferable to use such a cylinder as the exhaust means in manufacturing the food packaging bag.

してもよい。If the water content in the bag is particularly insufficient depending on the type or condition of the food or the cooking method, an appropriate water source may be stored together with the food. . Further, from the viewpoint of ensuring food hygiene, the food packaging bag may be further packaged with an outer bag, if necessary.

ようにすればよい。To package food in the food packaging bag, for example, the bag is prepared without heat-sealing only the bottom of the bag, and the bag in this state is provided to a food manufacturer or the like. Then, a food manufacturer or the like may store the food in this bag, heat seal the bottom, and complete the packaging.

に美味に調理される。Thus, for example, when meat buns are contained in the food packaging bag of the present invention, if the meat buns are cooked as they are in the microwave oven, the meat buns inside are heated and the air inside the bag expands. Further, at the same time, water vapor is generated, and the inside of the bag is in the same state as the steamer, and the internal pressure is maintained at the internal pressure up to a certain pressure. Further, when the internal pressure in the bag is about to rise, the bag is exhausted through the exhaust means, and the meat bun is cooked deliciously as if it was cooked in the steamer. Also, in the case of broiled eel, which is a frozen food, unlike the case of simply heating and thawing in a microwave oven, the eel is steamed at a constant internal pressure and cooked as delicious as the meat bun.

In this embodiment, the exhaust means 3 is configured as a meandering exhaust path 4 formed by heat-sealing the laminated films 1 and 1 forming the bag body 2. The meandering exhaust path 4 has a meandering path 9 formed by a heat-sealing wire 6 having a concave portion 5 and a heat-sealing wire 8 having a convex portion 7 formed on the upper side of the bag body 2. It is formed so as to communicate with the exhaust port 10, and is set so that when the pressure inside the bag body 2 reaches a constant pressure, the pressure does not rise any further. In this embodiment, when the internal pressure in the steaming basket reaches the same level as the internal pressure, the exhaust is set so that the pressure does not rise further.

No. 2 has steam generated inside, and is in a steaming state similar to what is called a steam basket. When the inside of the bag body 2 reaches a certain pressure, air leaks from the exhaust port 10 and the bag body 2 finishes cooking without bursting. I was able to. Also, when I tried to eat the cooked meat bun, it was steamed very deliciously. It should be noted that, when the bag 2 was filled with frozen eel kabayaki food instead of meat buns and cooked in a microwave oven as described above, it was cooked as delicious as the meat buns.
