Abstract

The bag has a plastic inner layer (2) i.e. perforated foil, and an outer layer (1) sectionally connected with each other. The inner layer has air through-flow openings (9) for primary ventilation of an inner space of the bag during a filling process with powder dusty filling goods. The outer layer is formed of a plastic foil, and has a secondary vent for permanent ventilation of the bag after closing the bag and enabling slow gas leakage. A longitudinal sealing seam (6) with a ventilation channel is provided as the secondary vent in a region of a longitudinal edge (5) of the bag.
