ABSTRACT:
A sheeting web consisting of foldable material, preferably of paper or cardboard, is described. The web enables a product, preferably a liquid, to be packaged continuously. The sheeting web has parallel spaced longitudinal edges (31, 32). Four continuous longitudinal folds (4) running parallel to the longitudinal edges (31, 32), uniformly spaced continuous first transverse folds (6, 7, 8) at right angles to the longitudinal edges (31, 32), and continuous second transverse folds (71, 8) at a given distance from and parallel to the first transverse folds (6, 7, 8) are provided, with the result that four contiguous rectangles in a transverse direction and a rectangular end strip connected to these are available. Alternate non-contiguous rectangles together with the rectangular end strip each have a third transverse fold (15, 10) running parallel to the first transverse fold (6, 7, 8) and equidistant therefrom and each have a fourth transverse fold (33, 10) running parallel to the second transverse fold (15, 10) and at the same distance as the third transverse fold from the first. The remaining two rectangles each have a central longitudinal fold (13) located in the middle of the rectangle which is shorter than the distance between the third and fourth transverse folds. Four diagonal folds (1) are provided each running from the two opposite ends of the central longitudinal fold (13) to the two nearest corners of the respective rectangle. Four rectangles, and also four inclined folds (12) are provided each running from the two ends of the central longitudinal fold (13) to the nearest intersection of the third and fourth transverse folds with the longitudinal folds (4) in the other rectangles or the end strip (FIG. 5).
