A method of producing and filling a paperboard packaging container with bulk solids material comprising forming a tubular container body, closing an upper body opening of the tubular container body, filling bulk solids into the container body a bottom body opening of the tubular containing body, closing the bottom body opening, and turning container body such that an upper end is directed upwards in a vertical direction, thereby allowing improved control of the pressure within the packaging container.

The present invention refers to a container precursor, comprising a sheetlike composite; wherein the sheetlike composite comprises as a layer sequence in a direction from an outer surface of the sheetlike composite to an inner surface of the sheetlike composite a) an outer polymer layer, b) a colour application, c) a carrier layer, and d) a barrier layer; wherein the sheetlike composite forms a wall of the container precursor; wherein the wall a. at least partly surrounds an interior of the container precursor, and b. comprises a first wall region and a second wall region; wherein the first wall region partly comprises as a layer sequence from the interior outwards a first ply, a second ply, and a third ply, in each case of the sheetlike composite; wherein in the first wall region the first ply is bonded to the second ply and the second ply is bonded to the third ply; wherein the second wall region partly comprises as a layer sequence from the interior outwards the first ply, the second ply, and the third ply, in each case of the sheetlike composite; wherein in the second wall region the second ply is bonded to the third ply; wherein at least the carrier layer and the barrier layer extend into the first ply, the second ply, and the third ply; wherein in the first wall region: in the second ply a layer thickness of the carrier layer is less than in the first ply, or in the third ply, or in both; wherein in the second wall region: in the third ply a layer thickness of the carrier layer is more than in the first ply, or in the second ply, or in both. The invention further refers to a closed container, obtainable from the container precursor; and to a closed container having the above sheetlike composite, the first and the second wall region.

A foldable storage box has four hard side surfaces in a vertical direction, a soft bottom surface, and a hard support plate that matches the bottom surface and is disposed on the bottom surface. Each of the side surfaces has a non-woven fabric interlayer, and a hard plug board is inserted in the interlayer. At least one pair of the four side surfaces are capable of being folded along a vertical folding axis. Vertical flexible dividing lines are disposed at intersections of the four side surfaces and the vertical folding axis, and the flexible dividing lines confine and isolate the respective hard plug boards in a horizontal direction. The flexible dividing lines are formed by welding two layers of non-woven fabrics in an ultrasonic welding manner.

In order to successively make plastic bags each of which includes panel portions, side gusset portions and a zipper portion, a web of panel material 9 is folded and folded back along longitudinal folded lines 14, 15 and 16 and longitudinal folded back lines 17 and 18 into superposed two layers having opposite side edges at each of which a folded portion is formed. The web of panel material 9 is slit along the longitudinal folded line 16 into two divided parts after being folded and folded back. The divided parts are separated and spaced from each other. In addition, the folded portions are split at positions into sprit portions and removed at the positions partially, a body of zipper material being disposed between the sprit portions.
