Water-based barrier coating formulations for fiber-based food-packaging are evolving to meet the demands for recyclable, bio-degradable and compostable materials. However, it´s not easy to fulfill the requirements set by the brand owners as well as tightening legislation, by the current technologies.

We will demonstrate the effect of a novel food contact approved commercially available additive on the performance of water-based dispersion barrier coatings and show how it can improve the barrier performance, applicability and drying properties of the coatings. It is possible to reduce the coat weight by 30% and still obtain better barrier performance against, for example grease and water, even on low-quality paper.

This will have a strong impact on the sustainability of packaging, saving in raw material cost and help to obtain plastic fiber ratio that meets the limits set by the regulations.
