Macromolecular medicinal packaging material and preparation method thereof

The invention relates to the technical field of packaging materials, and particularly discloses a polymer medicinal packaging material and a preparation method thereof. The polymer medicinal packaging material is mainly prepared from the following raw materials in parts by weight: 55-63 parts of low-density polyethylene, 20-30 parts of linear low-density polyethylene, 4-6 parts of modified silicon dioxide, 0.5-0.9 part of calcium stearate and 0.1-0.5 part of an antioxidant. The modified silicon dioxide is mainly prepared from the following raw materials in parts by weight: 100 parts of ethyl orthosilicate, 4 to 6 parts of zinc nitrate, 2 to 4 parts of magnesium nitrate, 0.5 to 1.5 parts of a dispersing agent, 4 to 6 parts of carboxymethyl chitosan, 1 to 3 parts of 3-(2-aminoethylamino) propyltriethoxysilane, 100 to 150 parts of an ethanol water solution and 50 to 150 parts of methylbenzene. The packaging material has the advantages of high antibacterial property and high tensile strength. 本申请涉及包装材料技术领域，具体公开了一
