The work aims to review the latest research progress of cellulose-based films, textiles, and aerogels with packaging potentials and EMI shielding capacities, so as to promote the in-depth research on cellulose-based electromagnetic interference (EMI) shielding materials for packaging. The preparation methods, electromagnetic interference (EMI) shielding performance, versatility, and potential application in packaging of cellulose-based films, textiles, and aerogels were introduced. The present cellulose-based electromagnetic shielding materials exhibited satisfactory EMI shielding effectiveness (EMI SE) and mechanical properties and were promising as packaging materials. Meanwhile, some materials also showed antibacterial properties, thermal insulation, and impact resistance and could be used in more complex scenarios. Through reasonable design, cellulose-based EMI shielding materials can possess excellent EMI shielding performance, excellent mechanical properties, and good durability. Due to the above advantages and green and degradable properties, these materials are expected to replace traditional EMI shielding packaging materials in the future. However, these materials usually require elaborate fabrication techniques, so the mass production of these materials is still an urgent problem to be solved.
