The development of the composite modified polylactic acid industry may benefit from the implementation of dual carbon targets

Composite modified polylactic acid is based on pure polylactic acid. By adding other modified auxiliary materials, the material can exceed the inherent property limitations of polylactic acid materials in certain physical and mechanical properties, thereby adapting to specific needs. The composite modified polylactic acid appears in the shape of rice grains, but its size and gloss are different. Composite modified polylactic acid can be used as a material for manufacturing tableware, household products, baby bottles, water cups, 3D printing, etc.

Since 2017, national competent authorities represented by the National Development and Reform Commission, the Ministry of Industry and Information Technology, and the Ministry of Science and Technology have issued documents and policies to actively encourage, support and promote the development of bio-based and degradable materials represented by polylactic acid. It is clearly encouraged development, key development, and key new materials, and is part of the carbon neutrality and carbon peak promotion projects. Therefore, composite modified polylactic acid is also a key product encouraged, supported, and promoted by the state.

At the beginning of 2020, the “Opinions on Further Strengthening Plastic Pollution Control” issued by the National Development and Reform Commission and the Ministry of Ecology and Environment specified the end of 2020 as the first key time point for “plastic restriction and ban”. As a result, domestic polylactic acid and The terminal market for compound modified polylactic acid has developed rapidly starting from disposable plastic tableware and plastic products. The market size has increased rapidly with the growth of the domestic takeout market, and with the trend of “replacing non-degradable plastics with degradable materials”, It continues to penetrate and develop into other fields where plastic materials are widely used.

At present, the domestic composite modified polylactic acid industry is in the early stages of development. Although the production process and technology of composite modified polylactic acid are continuously improved, the market price of composite modified polylactic acid is still significantly higher than that of traditional non-degradable plastics. According to the “Global and China Compound Modified Polylactic Acid Industry In-depth Research Report in 2022” released by the Industrial Research Center, compound modification The market price of polylactic acid is 22,000-29,000 yuan/ton, while the market price of traditional plastics PE, PS, and PP is 08,000-14,000 yuan/ton. Therefore, driven by material price factors, the downstream plastic products industry has low motivation to spontaneously adopt composite modified polylactic acid to replace traditional non-degradable plastics, and more relevant laws, regulations and policies are urgently needed to promote market development.

Industrial researchers believe that compared with petroleum-based materials whose raw materials cannot be regenerated in a short time, composite modified polylactic acid materials will The raw material end is incorporated into the biomass resource regeneration and recycling system, making it a material that is conducive to achieving the dual carbon goal of “carbon neutrality and carbon peaking”. At the same time, with the development of plastic modification and blending technology in recent years, composite modified polylactic acid has reached or even exceeded some traditional petroleum-based plastics in terms of hardness, mechanical strength, and heat resistance. Compound modified polylactic acid has broad demand prospects. Potential entrants can expand production scale, improve production efficiency and product quality by building new production bases, purchasing advanced equipment, and introducing professional talents based on their own business scale and advantages. Lay a solid foundation for occupying a dominant position in future market competition.
