Abstract

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 mildewproof agent. The processing method of the mildew-proof traditional Chinese medicine beverage packaging bag comprises the following steps: step 1, uniformly stirring the polymer matrix and the maleic anhydride grafted polyethylene, conducting blending through a double-screw extruder, carrying out melt extrusion, conducting cutting toform particles by using a granulator; and 2, uniformly mixing the particles prepared in the step 1 with a mildew preventive, connecting a single-screw extruder with a casting machine, carrying out melt extrusion to prepare a packaging bag film, and carrying out slitting and bag making to obtain the mildew-resistant traditional Chinese medicine beverage packaging bag. On the premise that the mildew-proof effect of the packaging bag is guaranteed, a coupling agent reacts with the microfibrillated cellulose and the linear low-density polyethylene in a bidirectional mode, combination of the microfibrillated cellulose and the linear low-density polyethylene is achieved, and the mechanical property of the packaging bag is improved.

Description

technical field [0001] The invention belongs to the technical field of medical packaging, and in particular relates to a mildew-proof traditional Chinese medicine beverage packaging bag and a processing method thereof. Background technique [0002] At present, when patients take traditional Chinese medicine, they generally adopt various Chinese herbal medicines prepared by hospitals in traditional Chinese medicine, and the patients themselves decoct them according to the doctor's advice. Due to various reasons, the medical effect is often not achieved. Some medical units decoct traditional Chinese medicine and put them in plastic bottles. Although it is convenient to carry, it is not easy to preserve. [0003] The invention patent CN107385991A mainly relates to the technical field of wrapping paper processing, and discloses an antibacterial and mildew-proof wrapping paper, which is made of the following raw materials: corn straw, wheat straw, humulus, mulberry leaves, madder...
