Transparent paper in packaging applications – step 1

The project ran between May and September 2020.

This project gives promise in the development of new innovative packaging materials from forest raw material. The material and the manufacturing process are unique compared to existing transparent packaging materials and have been in a co-operation by KTH Royal Institute of Technology and BillerudKorsnäs.

The hypothesis of this project was that transparent paper can be used for packaging applications and replace plastic. The hypothesis was tested by making of modified pulp and transparent paper in laboratory scale at BillerudKorsnäs Tech Center with the technical support from KTH. The material was successfully incorporated in three different type of packaging demonstrators showing it´s applicability in packaging applications to replace plastic. A business concept was developed for the new material based on brand-owner feedback of the demonstrators. Based on the feedback, there are interest from the market for new types of sustainable packaging materials that challenge plastics.
