The invention relates to the technical field of plastic woven bags, and particularly discloses an environment-friendly plastic woven bag and a preparation method thereof. The environment-friendly plastic woven bag is prepared from the following raw materials in parts by weight: 40 to 60 parts of polypropylene, 20 to 30 parts of poly (butylene adipate-co-terephthalate), 0.5 to 1 part of fluorescent whitening agent, 0.3 to 0.5 part of modified nano cellulose, 2 to 3 parts of starch, 0.5 to 1 part of inorganic pigment and 5 to 10 parts of filling master batch, the modified nano cellulose is obtained by coating and modifying hydrophobic nano magnesium oxide. The weight loss rate and the microbial degradation rate of the environment-friendly plastic woven bag obtained by the invention after illumination are respectively 88% and 36% at most, and the weight loss rate and the microbial degradation rate after pyrolysis are respectively 79% and 36% at most, so that the degradation efficiency of the ...
