The invention discloses a mildew-proof traditional Chinese medicine beverage packaging bag which comprises the following raw materials in parts by weight: 100-200 parts of polymer matrix, 5-10 parts of maleic anhydride grafted polyethylene and 10-12 parts of mildew preventive; the processing method of the mildew-proof traditional Chinese medicine beverage packaging bag comprises the following steps: uniformly stirring a polymer matrix and maleic anhydride grafted polyethylene, blending through a double-screw extruder, carrying out melt extrusion, cutting into particles by using a granulator, uniformly mixing the particles prepared in the first step and a mildew preventive, connecting the particles with a casting machine through a single-screw extruder, carrying out melt extrusion to obtain a packaging bag film, and then slitting and bag making to obtain the mildew-proof type traditional Chinese medicine beverage packaging bag; on the premise of ensuring the mildew-proof effect of the packaging bag, the coupling agent reacts with the microfibrillated cellulose and the linear low-density polyethylene in a two-way manner, so that the combination of the microfibrillated cellulose and the linear low-density polyethylene is realized, and the mechanical property of the packaging bag is improved. |
