Hot pressing

Consolidation and hot pressing of biomaterials for applications in the packaging area

The purpose of the project is to develop process technology with a focus on consolidation via hot pressing of above all high yield masses and to increase the fundamental understanding of the mechanisms that arise. The goal is to find ways to manufacture new sustainable and circular cellulose-based materials for applications in the packaging area.

In order for forest biomaterials to be able to replace plastics to an even greater extent than is done today, research in the field needs to be broadened and new techniques developed. One part of this is to further develop the hot pressing technology, which in previous studies has been shown to provide considerable improvements in both dry and wet strength without chemical additives.

The idea is to study how we can optimize and control the fiber networks' degree of consolidation by combining variables such as temperature, pressure and constituent mass components (primarily, HYP), this in order to be able to design different types of packaging materials.

We therefore want to combine the quality-enhancing effect that hot pressing gives with different fiber properties (different fiber raw materials and pulp manufacturing processes), addition of biodegradable components, and use different pre- and post-treatment of the material in order to reach the desired product properties.
