How many enterprises produce starch based plastics in China

more than 40 kilograms can be used for blistering
polylactic acid (PLA)
lactic acid can be produced by using fermented sugar from cereals or other organics, and lactic acid can be polymerized to obtain a linear aliphatic polyester polylactic acid (PLA) The degradation of PLA is divided into two stages. The first stage is that its ester group is gradually hydrolyzed into lactic acid and other small molecules, and then these small molecules are decomposed by microorganisms in the environment
PLA is often blended with starch to enhance its degradability and reduce its cost However, the blend is too brittle, so some plasticizers such as glycerol and sorbitol are often added to make it soft Some producers also often use other degradable polyester blended with PLA to replace plasticizer
PLA material has smooth surface and high transparency, so it can compete with polystyrene and pet in some application fields PLA has been applied to hard packaging of fruits and vegetables, eggs, cooked food and baked goods PLA film is being used in the packaging of sandwiches, biscuits and flowers In addition, PLA is blown into bottles for packaging water, soup, food and edible oil Some carmakers, most notably Japan’s Toyota, are conducting research into the use of PLA and other biodegradable plastics in future cars

there are not many large enterprises. With the development of fast food industry and logistics industry, there are a lot of biodegradable plastics in the market, many of which are produced by small factories. Because small factories produce a lot, this is not easy to count
approximate scale and market: the world’s synthetic resin has reached 150 million tons, including about 15 million tons of plastic produced in China, about 3 million tons of plastic waste produced every year, about 1.5 million tons of secondary recycling, and about 1.5 million tons of non recyclable plastic waste, including plastic packaging films, bags, lunch boxes and other products such as plastic mulch and daily necessities
generally, if large-scale enterprises need to be built in this industry, it is better to build them mainly in calcium carbonate production area and starch production area. Typically, similar to Wuming in Guangxi, the packaging industry, calcium carbonate industry and starch alcohol industry used to be very good. However, due to the withdrawal of Wuming County into districts and the elimination of a large number of starch factories, it is estimated that degradable bioplastics are not well developed. Originally, there was a starch factory near the cement factory, which was originally suitable for the development of degradable bioplastics and modified nano calcium carbonate. Later, the development of the starch industry was restricted, and the factory was forced to close down, resulting in wrong policies.

at present, there are few leading enterprises in China. Hebei YUEGANG Biotechnology Co., Ltd. has fully entered the market with good feedback, low price and good quality
