Quality assurance par excellence. WEIG Packaging uses crease-bend-testers from Marbach to check the quality of paperboards.

We know the requirements of the packaging market all too well. This is precisely why WEIG Packaging integrated our crease-bend-tester – a quality assurance device – into its portfolio several years ago. It allows to check the accuracy of the creasing rules and the folding resistance of packaging before or even during production. Precisely positioned creasing rules in turn enable easy and precise folding and are also crucial for the shape and stability of the packaging. The crease-bend-tester therefore plays an important role in the production of high-quality packaging. This is why it is already in use at WEIG Packaging.

Lisa Gräbner, quality assurance employee at WEIG Packaging: "In the past, we assessed the set-up behavior and creasing of our paperboards manually or by visual inspection. This required a lot of professional experience and a high level of sensitivity on the part of the employee carrying out the inspection. Up until now, however, there were no valid, objective measured values for comparison. We wanted to change this and finally have the opportunity to verify the subjective perception of the folding carton using measured values. This step was crucial for us, as we wanted to check our suppliers' paperboards for compliance with the guaranteed specifications. In addition, the meaningful measured values also helped us to assess the quality of our own paperboards. Finally, they allowed us to better evaluate any complaints and process them accordingly. With these requirements in mind, we started looking for a suitable measuring device. Of course, we could not avoid Marbach and its extensive expertise in the field of die-cutting. We quickly realized that the crease-bend-tester met our requirements for testing the creasing resistance and bending stiffness of paperboard. Today, we can analyze creases very quickly and also determine the bending stiffness of the paperboard. I would recommend the crease-bend-tester to any folding carton manufacturer. It is a quick and easy way to create a valid database that serves as an independent basis for the technical assessment of cartonboard material and the folding cartons produced. Once again, a big thank you to Marbach, we were very satisfied with the entire process. We received an intensive introduction to the operation of the crease-bend-tester so that we were able to use it optimally and immediately after the training."
