Functional films based on hydroxypropyl methylcellulose (HPMC)/ sodium citrate (SC) porous film and liposoluble tea polyphenol (LTP)/water Pickering emulsions stabilized by different contents of starch nanoparticles (NPs) were prepared. Addition of Pickering emulsion endowed the film surface pores, decreased oxygen permeability, water vapor permeability (WVP), hydrophilicity and good anti-oxidant effect. With increasing NPs, more smaller emulsion droplets appeared in the emulsion and filled into the porous structures of the film, the light transmittance and contact angle of the film increased. Functional film with 2 % NPs showed the lowest WVP and T
