How are cellulose nanofibrils used as barriers in paper packaging?

Cellulose nanofibrils (CNFs) have gained significant interest as an effective barrier material in paper packaging. CNFs are renewable, biodegradable, and possess exceptional mechanical properties that make them suitable for enhancing the barrier properties of paper-based packaging materials. By incorporating CNFs into the paper matrix, a nanoscale network is formed, which prevents the permeation of gases, water vapor, and oils. This improved barrier performance helps extend the shelf life of packaged goods by reducing moisture absorption and preventing the entry of external contaminants. Furthermore, the use of CNFs as barriers in paper packaging aligns with the growing demand for sustainable packaging solutions, as it enables the replacement of non-renewable and non-biodegradable barrier materials such as plastics, benefiting both the environment and consumers.
