ABSTRACT:
A strip made up of consecutive package blanks has been described. This strip consists of cardboard and has continuous longitudinal folding lines, which divide each blank into longitudinal zones, and in each blank four transversal folding lines which divide the blank into five transversal zones. Thus each blank can be folded to become a package wherein the centermost transversal zone constitutes the rectangular sides of the package, the transversal zones following on either side and which have on the areas of the longitudinal zones, which in the folding process come to be opposite each other, oblique folding lines enabling a folding up constitute the ends of the package and the edgemost transversal zones constitute at the ends seams which close the package. The seams are formed by cardboard layers that are lying against each other and bonded together with the aid of plastic. Those longitudinal zones, in which the oblique folding lines are located, present on the dividing line between consecutive blanks in the cardboard apertures which have been covered with a plastic layer so that when the blanks are being folded the plastic covering the apertures will be doubled at the seams to be sandwiched between two opposed cardboard layers forming the seam.
