With　the　rapid　development　of　5G　communication　technology,　the　research　on　ultra-thin　flexible　electromagnetic　interference　(EMI)　shielding　materials　has　become　a　hot　topic.　The　next　generation　of　devices　is　moving　towards　miniaturization,　intelligence,　and　high　integration.　Considering　complex　application　scenarios,　single　function　EMI　shielding　films　no　longer　meet　cutting-edge　industrial　needs.　In　this　paper,　emerging　demands　and　applications　for　flexible　EMI　shielding　films　with　multifunctionality,　including　transparency,　thermal　conductivity,　joule　heating　or　photothermal　response,　hydrophobicity　and　self-cleaning　property,　corrosion　resistance,　fire　retardancy,　pressure　sensing,　ultra-high　mechanical　properties,　and　excellent　durability　were　comprehensively　summarized.　In　addition,　advanced　strategies　for　implementing　functional　integrity　of　EMI　shielding　materials　were　proposed.　The　fabrication　methods,　structures,　functions,　and　mechanisms　of　the　latest　research　progress　of　multifunctional　flexible　EMI　shielding　films　were　elucidated　in　detail.　Key　challenges　on　multifunctional　flexible　EMI　shielding　films　are　presented　followed　by　some　future　perspectives.
