Abstract: The life of electronic products, conversion efficiency of solar cells and food shelf life are highly
related to the oxygen and moisture resistance of packaging materials. It is of great significance to develop
cellulose based biodegradable barrier materials for packaging under double carbon targets and ban on free
plastic bags. Cellulose has been widely used in flexible packaging because of its rich resources, renewability,
good barrier properties etc. Herein, the research progress of cellulose-based barrier materials in recent years
was reviewed from perspectives of size difference, structures and physicochemical properties. The preparation
and barrier performance of regenerated cellulose, cellulose derivatives and nanocellulose-based barrier
films were then systematically described from the point of barrier mechanism, with an emphasis on the
influences of different cellulose matrix or functional fillers on the performance of composite barrier film.
Finally, the advanced applications of cellulose-based barrier films in the field of packaging materials was
summarized, followed by discussions on the challenges faced in the development of multicomponent
cellulose-based packaging barrier film materials.
