Abstract

The invention disclsoes a degradable granular medicine packaging material and a preparation method thereof. The degradable granular medicine packaging material is prepared from the following raw materials in parts by weight: 12 to 23 parts of hydroxypropyl methyl cellulose, 10 to 20 parts of chitosan, 3 to 7 parts of barium stearate, 10 to 15 parts of polyester fiber, 15 to 25 parts of wheat starch, 1 to 3 parts of methyl urea, 2.5 to 6 parts of natural resin adhesive, 3 to 9 parts of polyethylene glycol, 10 to 16 parts of sweet potato starch, 4.5 to 10 parts of talcum powder, 1.5 to 3 parts of emulsion adhesive, 4 to 9 parts of soluble chitin, 1.2 to 4.5 parts of sodium xylene sulfonate and 1.5 to 4.5 parts of dibutyl phthalate. The degradable granular medicine packaging material provided by the invention has a good degradation effect, and the preparation method is simple and is low in cost.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, in particular to a degradable granular medicine packaging material and a preparation method thereof. Background technique [0002] With the continuous improvement of people's cultural quality, the awareness of environmental protection is getting stronger and stronger, and people are more and more aware of the pollution caused by packaging materials to the environment, because after the packaging materials are abandoned, their strong stability can exist in the natural environment for a long time Among them, it is one of the important sources of pollution in people's production and life. The usual recovery methods are landfill or incineration, which not only consumes energy, but also causes secondary pollution to the environment. In recent years, while people are researching and solving waste plastic recycling technologies, degradable plastics have also become a research hotspot in the...
