Industry cooperation with SIG: Optimizing packaging through numerical modeling

SIG Combibloc is one of the world's leading companies for packaging technologies and solutions. If you take a closer look at a milk or juice carton, for example, you are very likely to see the SIG logo. This carton was probably produced at the plant in Linnich, North Rhine-Westphalia in Germany. In addition to production, the plant also houses a training center, a test filling center and an R&D department. This is where new products are developed and existing ones improved.

In the course of this, our cooperation was established years ago in order to be able to depict the material behavior of a packaging box using numerical models. The main focus was on modeling the paper core of the packaging.

In the current collaboration, the aim is to optimize our existing material models for paper for industrial applications. Furthermore, additional mechanical effects such as damage mechanisms are to be investigated and integrated into the model. With the help of these material models, the production and filling process can be realistically simulated. This is the key to reducing material waste in production, making damage scenarios predictable and improving packaging stability.
