Paper-Based Oil Barrier Packaging using Lignin-Containing Cellulose Nanofibrils
Environmental and health concerns are driving the need for new materials in food packaging to replace poly- or perfluorinated compounds, aluminum layers, and petroleum-based polymers.Cellulose nanofibrils (CNF) have been shown by a number of groups to form excellent barrier layers to oxygen and grease.However, the influence of lignin-containing cel
