摘要： The present disclosure relates to methods of producing a packaging container for bulk solids. The packaging container has an inner compartment and a transport closure closing the inner compartment, the transport closure being provided with a pressure relief valve, the method includes the steps of forming a tubular container body having an upper body opening; presenting the container body to an upper body opening sealing station comprising a plunger piston comprising a bottom plate, the bottom plate having a through hole; closing the upper body opening by pressing the transport closure into the upper body opening such that a pressure above an ambient pressure is produced within the tubular container body, allowing gas to exit the valve and the valve to be pre-conditioned; and attaching the transport closure to the container body wall.
