<p>A packaging method using a packaging tray that is assembled from a rectangular blank (P) of paper material, which is provided with a first fold line (5) parallel to its longitudinal edges at a distance corresponding to twice the desired height of the tray, a second fold line (6) being provided between said first line and the adjacent longitudinal edge, said fold lines extending substantially along the entire length of the blank, a third fold line (8) being provided parallel to each of the transverse edges at a distance corresponding to the height of the tray, said third fold lines being cut through from the longitudinal edge(s) inwardly up to the adjacent first fold line so as to form transverse cuts (9), in such a way, that the longitudinal side walls may be formed by upward folding about said first fold line and outward and downward folding about said second fold line, whereas the end walls are formed by folding about the third fold lines and flanges of said end walls - which are obtained by said cuts - will be caught between the inner longitudinal side wall seetions and the outerwardly and downwardly folded section of the respective longitudinal side wall. Upon filling the packaging tray is wrapped with and kept in shape by a tubular foil. <IMAGE></p> |
