Abstract (en)
[origin: EP2266450A1] The bag (1) has a diffuser (8) arranged on an inner side and formed by material strips and/or flat structures with elongated flow openings. A side of the diffuser is connected to a pouch wall, and the material strips are movable to each other, where width of the strips is 2 mm. The openings are arranged in parallel or in a zigzag pattern. Two diffusion sensors are arranged in overlapping manner such that the material strips and/or elongated flow openings are not arranged parallel to each other. The diffuser is made of air-permeable material i.e. film, and lengths of the openings are different.
