Perfection in die-cutting cigarette packaging

Marbach has some special technologies for the tobacco sector in its portfolio; the crease-plate-die|+ and crease-plate-die|rc not only ensure productivity during die-cutting, but also during the subsequent packaging process.

Bernhard Reisser, Industry Manager, Marbach, says, “The decision about which of the two technologies crease-plate-die|+ or crease-plate-die|rc is the most suitable, is determined solely by the design of the blank to be die-cut. For example, crease-plate-die|+ is always used when packaging has to be produced in a ‘hinge lid’ or ‘bevel edge’ design. With this technology, creasing is performed with a defined gauge block. This means that the make-ready can be carried out with extreme precision resulting in uniform creasing. This increases the quality of the packaging blanks and the speeds at which they can be packed.

The crease-plate-die|rc, on the other hand, is a solution specifically for cigarette packaging in round corner design. Reisser continues, “The effect of round corner packaging is created by the fact that several creases are close together when the packaging is cut. This looks remarkable on the finished packaging, but also places high technical demands on the tool. For example, round corner creases affect the paperboard in a completely different way than standard creases. In order to control these forces, the make-ready of the vertical creaser can optionally be separated from the round-corner creases of the crease-plate-die in the round-corner version. The results are high-quality blanks that meet the creasing specifications given by the end customer. By the way, due to the wide range of adjustment options on the creasing unit, this also applies to changing board materials and variations in board quality.”
