Abstract (en)
[origin: WO2007006060A1] Disclosed is a ventilatable bag comprising a flat web (1) of a bag material which is shaped into a tube by overlapping the longitudinal edge regions thereof, one end of said tube being closed or being embodied as a bottom. The bag material is impermeable to air while comprising perforations (1g, 1h) in subareas (1d, 1e; 1i, 1j; 1k, 1l, 1m, 1n; 1o, 1p, 1r, 1s) of the longitudinal edge regions. The perforations (1h) located in one longitudinal edge region (1e) are offset relative to the perforations (1g) located in the other, overlapped longitudinal edge region (1d). The overlapped longitudinal edge regions are fixed to the adjoining layer of the bag material (1) by means of a joint (2, 3). The perforations (1g) in the overlapped longitudinal edge region (1d) are provided with a configuration and/or an arrangement allowing less air to penetrate than the perforations (1h) in the overlapping longitudinal edge region (1e), perforations (1h) having a greater cross-sectional area and/or a larger number of perforations (1h) per surface unit being embodied in the overlapping longitudinal edge region (1e) than in the overlapped longitudinal edge region (1d).
