Cellulose

as a renewable resource in nature

has a wide range of sources. In energy-shortage situation

cellulose based materials have attracted more and more attention. Nano cellulose from plant resources has the characteristics of light weight

high strength and good gas barrier

which makes it widely used in food packaging materials. In this paper

the application of cellulose nanofibers

microcrystalline cellulose and cellulose nanocrystals and their barrier properties

mechanical properties

antibacterial properties and degradability in food packaging materials were reviewed. The effects of nano cellulose on the properties of food packaging materials were summarized. The combination of nano composite materials and multi-layer design has great potential in the field of food packaging materials.
