Manufacturing and processing technology of antibacterial plastic meal box

The invention relates to the related technical field of plastic meal boxes, and discloses an antibacterial plastic meal box manufacturing and processing technology which comprises the following steps: S1, weighing the following raw materials in parts by weight: 60-80 parts of polylactic acid, 8-12 parts of Arabic gum and 2-3 parts of sodium bicarbonate; by adding and mixing the raw materials, the purpose that the antibacterial environment-friendly tableware has good mechanical property, antibacterial property and degradation property can be achieved, the plastic meal box has the antibacterial effect, and meanwhile the performance of the plastic meal box is further enhanced; alkenyl unsaturated bonds are introduced into inorganic filler by adopting itaconic anhydride modified starch, a double-bond part is easier to break during degradation, and the degradation rate is increased; therefore, the problem that the meal box cannot be effectively degraded is avoided, the pollution problem is greatly reduced, in addi
