Abstract

See full text

A packaging container of the type being flat when empty for receiving bulk material includes a moisture-proof, thermoplastic layer connectable along a longitudinal seam which is defined by longitudinal edges and having a ventilation zone spaced in parallel relationship to the longitudinal edges and closable through heat sealing or welding after feeding bulk material into the interior and ventilating the bulk material. The ventilation zone of the packaging container is formed by initially leaving one of the longitudinal edges of the longitudinal seam open. Only after the packaging container is filled and the contents are allowed to ventilate is this initially open seam area closed by a welding or heat sealing process.
