Polylactic acid (PLA), also known as polylactide, is an aliphatic polyester made by dehydration polymerization of lactic acid produced by microbial fermentation as a monomer. It uses renewable biomass such as corn, sugar cane, and cassava as raw materials, and has a wide range of sources and can be renewable. The production process of polylactic acid is low-carbon, environmentally friendly, and less polluting. After use, its products can be composted and degraded to realize the cycle in nature. In addition, it is widely used and has a lower cost than other common degradable plastics such as PBAT, PBS, and PHA. Therefore, it has become the most active and fastest-growing biodegradable material in recent years.

The development of polylactic acid is highly valued globally. In 2019, the global PLA’s main applications in packaging and tableware, medical and personal care, film products, and other end markets accounted for 66%, 28%, 2%, and 3% respectively.

The market application of polylactic acid is still dominated by disposable tableware and food packaging with a short shelf life, followed by semi-durable or multiple-use tableware. Blown film products such as shopping bags and mulch are strongly supported by the government, and the market size may have a large-scale jump in the short term. The market for disposable fiber products such as diapers and sanitary napkins may also rise sharply under the requirements of regulations, but its composite technology still needs a breakthrough. Special products, such as 3D printing in small amount but high added value, and products that require long-term or high-temperature use, such as electronics and car accessories.

It is estimated that the annual production capacity of polylactic acid worldwide (except China) is about 150,000 tons and the annual output is about 120,000 tons before 2015. In terms of the market, from 2015 to 2020, the global polylactic acid market will grow rapidly at a compound annual growth rate of about 20%, and the market prospects are good.
In terms of regions, the United States is the largest production base of polylactic acid, followed by China, with a production market share of 14% in 2018. In terms of regional consumption, the United States still maintains its leading position. At the same time, it is also the world’s largest exporter. In 2018, the global polylactic acid (PLA) market was valued at US$659 million. As a degradable plastic with excellent performance. Market insiders are optimistic about the future market
