Bio-Based Dual-Layer UV-Cured Oil- and Water-Resistant Paper Coating for Food Packaging Applications
Despite its title referencing bio-based paper coatings for food packaging, this paper studies how chitosan and plant-oil-derived coatings can replace fluorine-based chemicals on paper food packaging to resist water and oil — not microplastic pollution. It examines barrier performance and mechanical strength and is not relevant to microplastics or human health.
