The comprehensive properties of starch-based degradable plastics currently developed, such as mechanical strength, heat resistance, and moisture resistance, are still different from those of traditional plastics. In terms of degradation, it has not yet reached the level we expected. Most of the biodegradable plastics are locally weightless, broken into small pieces, and have not completely disappeared. And the cost is high. In order to ensure its comprehensive performance, auxiliary agents need to be added in the preparation process, resulting in an increase in cost. If you want to promote it on a large scale, you will be limited in price.

In 2020, my country issued the "Opinions on Further Strengthening the Control of Plastic Pollution" to once again intensify efforts to rectify the problem of plastic pollution. Clearly divided into three nodes, 2020, 2022, and 2025, to ensure a large reduction in the use of plastic products, which means that part of the demand for traditional plastics will shift to degradable plastics. If calculated by replacing 50% of traditional plastics, the annual increase The demand for degradable plastics is 2.5 million tons, which is an emerging area worthy of attention. Starch is one of the most price-competitive advantages of bio-based plastics, and has broad development prospects in the sustainable development strategy. The following three points should be paid attention to in the research of starch-based degradable plastics:

(1) At present, the compatibility of starch-based degradable plastics is a research hotspot, and the development of environmentally friendly compatibilizers can make starch more compatible when mixed with other materials.

(2) Improve the comprehensive performance of starch-based degradable plastic products, so that their applications are not limited to mulch films, drug capsules, packaging materials, etc., and higher-end markets should be developed.

(3) If nanotechnology or new materials are applied to biostarch-based plastics, the properties of plastic products will undergo a qualitative leap.
