A culturing bag for microorganisms has a wall formed of plastic film wherein at least one wall area of the wall is permeable for oxygen and carbon dioxide. A first layer of microporous film is attached to the at least one wall area as an exterior layer so as to form a multi-layer configuration in the at least one wall area. The first layer of microporous film is sealed by a seal-tight edge seam to the wall. The microporous film is adapted to be torn open or torn off. At least one second layer of microporous film can be placed between the exterior layer and the wall.
