The invention provides a nano packaging material with a fresh-keeping effect and a preparation method thereof. The preparation method comprises the following steps: mixing wollastonite and sepiolite, grinding the mixture in a grinder, and sieving the ground mixture through a 200-mesh sieve to obtain a mixed powder; adding nano-silver powder, nano-titanium dioxide, deacetylated chitin, low-density polyethylene, ethylene-vinyl alcohol copolymer, tea tree essential oil, vetiver essential oil, silane coupling agent Si-602, N-γ-aminopropyltrimethoxysilane, ethylene bis-stearamide, oleamide and antioxidant 1076, and mixing the mixture in a high-speed mixer; performing extrusion and pelletizing through a twin-screw extruder; and performing blow molding by a blow molding machine after cooling to obtain the final product. The nano packaging material with a fresh-keeping effect of the invention has good tensile strength, excellent fresh-keeping effect, effective moisture retention, oxygen isolation to reduce the harm of oxidation, and also has good antibacterial effect with high antibacterial rate.
