There is described a packaging machine for producing sealed packages of a pourable product from a web of packaging material, which may include conveying means for advancing the web of packaging material along a web advancement path at least to a tube forming station at which the web of packaging material is formed into a tube and for advancing the tube along a tube advancement path, an isolation housing having a main chamber and an auxiliary chamber arranged downstream of the main chamber along the tube advancement path, a tube forming and sealing device at least partially arranged within the main chamber and being configured to form and longitudinally seal the tube within the main chamber, a filling device for filling the tube with the pourable product and a pressure control device configured to control a first pressure within the main chamber and a second pressure within the auxiliary chamber such that the first pressure is higher than the second pressure and the first pressure and the second pressure are both higher than the ambient pressure.

A bag-making and packaging apparatus, for forming a bag containing a packaged article from a conveyed packaging material, is disclosed. The apparatus includes a printing part, first and second receiving parts, and a retaining part. The printing part prints information on the packaging material. The first receiving part is used in a first mode to print on the packaging material during conveyance without stopping conveyance. The second receiving part is used in a second mode to print on the packaging material at a timing when conveyance of the packaging material is stopped. The retaining part retains the first receiving part or the second receiving part so that the first receiving part and the printing part face each other with the packaging material disposed therebetween in the first mode, and the second receiving part and the printing part face each other with the packaging material disposed therebetween in the second mode.
