The ideal biodegradable granular plastic is a kind of polymer material with excellent performance, which can be completely degraded by environmental microorganisms after being discarded, and eventually become inorganic and become an integral part of the carbon cycle in nature. The main component of stone paper is 70%. Calcium carbonate is left and right, and the rest is high-molecular polymer as an auxiliary material. The degradability is a little worse than that of plant residues. Stone paper is automatically degraded into powder by sunlight temperature.
"Paper" is a typical biodegradable granular material, while "synthetic plastic" is a typical polymer material. Therefore, biodegradable granular plastics are polymer materials with both material properties of "paper" and "synthetic plastics".
The market positioning of stone paper is disposable packaging bags for plastic packaging products, disposable tableware, agricultural films, etc. Compared with traditional plastic packaging materials, the cost of new degradable materials is slightly higher. However, with the enhancement of environmental protection awareness, people are willing to use new degradable materials with a slightly higher price to protect the ecological environment. The enhancement of environmental protection awareness has brought great development opportunities to the biodegradable new material industry.
There are abundant limestone mineral resources in various regions of our country. The production of inorganic powder and environmentally friendly stone paper has the potential to enhance and expand the application value of our country. It also greatly promotes the development of my country's paper industry and polymer material processing industry. environment, expand domestic demand, and stimulate local economic growth.
