In recent years, there has been a notable shift from plastic packaging to fibre-based alternatives. Ensuring that fibre-based packaging maintains all functionalities of its plastic counterpart is essential. This research focuses on a specific aspect of this transition: the resistance to water and moisture.

A critical divergence in material properties between LDPE (Low-Density Polyethylene) and fibre-based materials lies in water resistance. The inherent lack of natural water resistance in fibre-based materials underscores the importance of coatings in the success of fibre-based packaging. To address this challenge, two specially designed coatings were developed in collaboration with chosen companies. Following to a promising lab testing phase, a dedicated testbench was constructed for practical real-life evaluations.

Close cooperation with a coating research company played a key role in unveiling the true potential of these coatings. Particularly, a bio-based coating emerged as a viable solution to enhance water resistance in paper packaging.
