The work aims to review the research progress of paper properties modified by nanomaterials at home and abroad, and to provide scientific research basis for further developing the application of nanomaterials in packaging industry. The method used to modify paper properties by nanomaterials was reviewed, and the influences of nanocellulose, chitosan nanoparticles , nanoclays, nano-oxide and metal nanoparticles on paper packaging properties were respectively analyzed, and the relevant research progress at home and abroad was analyzed. Finally, the application fields and development prospects of nanomaterial modified packaging paper were summarized. A large number of research results have shown that it is an effective way to improve the surface properties, optical properties, mechanical properties, printability and barrier properties of paper when the nanomaterials are added during papermaking or applied on the paper surface.
