Cardbox Packaging GmbH Wolfsberg would like to develop coated cardboard packaging with the following properties:

Very good water resistance and wet strength, food suitability, recyclability, compostability, resource conservation and low global warming potential.
This should serve as a more sustainable alternative to PE extrusion-coated cardboard.

Three small, open cardboard boxes are positioned in a row. The one on the left is green, the one in the middle is pink and the one on the right is blue.

In the run-up to the project, a special barrier coating system was therefore developed in collaboration with a coating manufacturer, in which good water and grease resistance could already be achieved.

In the course of the project, the suitability of the formulation for the fulfilment of the aforementioned requirements was to be evaluated, test procedures compiled and concepts for the further development of the formulation for food applications created. In addition, resource conservation and ecological sustainability were to be assessed using streamlined LCA.

Research Goals

Classification of the present coating for suitability in principle for the intended food applications
Concept(s) for further development of the formulation and process
Ecological rough classification
