ClearChitosan–Graft–Poly(dimethylsiloxane)/Zein Coatings for the Fabrication of Environmentally Friendly Oil- and Water-Resistant Paper
Researchers developed a sustainable paper coating using chitosan-graft-poly(dimethylsiloxane) and zein biopolymers that provides oil and water resistance, offering a biodegradable alternative to conventional synthetic polymer coatings that contribute to microplastic pollution. The approach demonstrates a practical strategy for reducing plastic waste in paper packaging applications.
Fabrication of water/oil-resistant paper by nanocellulose stabilized Pickering emulsion and chitosan
Researchers developed a plastic-free, biodegradable water- and oil-resistant paper coating using cellulose nanofibrils and chitosan in a Pickering emulsion system. The coating provided excellent barrier properties against water and oil while maintaining paper recyclability and compostability. The study offers a promising alternative to conventional plastic-based food packaging coatings that contribute to microplastic pollution.

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.
Sustainable Water- and Oil-Repellent Coating for Disposable Meal Boxes Based on Highly Deacetylated Chitosan
Researchers developed a sustainable, fluorine-free chitosan-based coating for paper meal boxes that provides water and oil resistance, offering an environmentally safer alternative to conventional petrochemical and fluorinated coatings that generate microplastics and PFAS contamination.
A Fully Plant-Based Water- and Oil-Resistant Paper Composite
Researchers developed a fully plant-based paper composite coated with lignin as a water- and oil-resistant alternative to plastic-coated or PFAS-treated food packaging. Optimized hot-pressing conditions produced a coating that resisted water for 100 minutes and oil for 25 minutes, and the material fully biodegraded in garden soil within 56 days.
Bio-Based Monoepoxy-TerminatedPolysiloxane-ModifiedCoating for Hydrophobic and Oil-Resistant Paper
Researchers developed a bio-based coating material by grafting monoepoxy-terminated polysiloxane onto chitosan and cellulose nanofibers via a one-pot method, producing films with tunable hydrophobic and oil-resistant properties for sustainable packaging paper as an alternative to nondegradable plastic coatings.
Degradable Polymeric Waxes for Paper Coating Applications
Scientists created degradable wax-like polymers that can coat paper packaging to make it water- and oil-resistant, offering an alternative to traditional plastic coatings. Unlike conventional plastic-coated paper, these coated papers can be broken down and recycled through standard paper repulping. This kind of innovation could help reduce the microplastic pollution that comes from plastic-coated packaging materials breaking down in the environment.
Sustainable Packaging with Waterborne Acrylated Epoxidized Soybean Oil
Researchers developed a sustainable packaging material by coating kraft paper with waterborne acrylated epoxidized soybean oil.
