Abstract (en)
[origin: EP0795482A2] A food product packaging bag (20) includes a bag body made of a synthetic resin (10), and an air discharge means (30) which is adapted to ensure that when the internal pressure in the bag (20) exceeds a predetermined level, air is discharged to prevent the internal pressure in said bag (20) from being risen more than a given value. Thus, when a food product is cooked in a microwave oven while remaining packed in the bag (20), it can be heated, and air in the bag expanded to rise the internal pressure. However, when the internal pressure exceeds a given level, the air is discharged to the outside through the air discharge means (30). In this manner, the food product can be cooked into a good taste. <IMAGE>
