The invention discloses a BOPET film for with a water-based anti-reflection coating coated online and a preparation method of the BOPET film. The BOPET film comprises a BOPET substrate layer and the water-based anti-reflection coating which is adhered to at least one surface of the substrate layer, wherein the water-based anti-reflection coating contains refraction particles with the diameters of 0.01 to 10 microns and the refraction index of 1.3 to 1.45; the water-based anti-reflection coating is formed by longitudinally drawing a PET slice and coating a water-based anti-reflection coating liquid onto the surface of the PET slice online, wherein the water-based anti-reflection coating liquid contains larger than or equal to 50 weight percent of water, and the refraction particles are 100 ppm and 1,000 ppm. According to the BOPET film, the overall light transmittance is larger than or equal to 94 percent and is improved by about 6 percent when compared with that of a BOPET film without ...
