Biodegradable plastics, also known as green plastics, can be completely or partially converted into water, CO2 / methane, energy and new biomass under the action of microorganisms (bacteria and fungi). Biodegradable plastic bags, in accordance with the standard of plastic bags in certain conditions, such as the temperature reaches 70 degrees, CO2 sufficient environment can be biodegradable. Therefore, when biodegradable plastic bags enter the ocean and other non-standard environment, the biodegradability of plastic bags will be reduced. Therefore, the selection of suitable biodegradable plastic bags should also deal with the used bags under the appropriate environmental requirements.
The main difference between degradable plastic bags and ordinary plastic bags is that the former does not contain PE in general garbage bags, but mainly comes from lignin extracted from straw and biodegradable plastics.
China’s annual output of plastics is 30 million tons, and its consumption is more than 6 million tons. If the annual plastic waste of plastic bags is calculated by 15%, the annual plastic waste in the world is 15 million tons, while the annual plastic waste in China is more than 1 million tons, and the proportion of waste plastic in the garbage accounts for 40%. Such a large amount of waste plastic is buried underground as garbage, which undoubtedly brings greater pressure on the arable land that is lacking.
The world is facing the same problem, so the market prospect of degradable plastic bag products is not only limited to the domestic market, but also covers almost every corner of the earth. From the overall trend, degradable plastic bags have gradually become the development trend. The increase in the price of plastic bags will encourage some people to use cloth bags for shopping. In this regard, it is beneficial to environmental protection. In the next 3-5 years, it will quickly occupy the market and become a substitute for ordinary plastic products. According to the industry forecast, the global packaging market demand for degradable plastics will reach 9.45 million tons in 2023, with an average annual compound growth rate of 33%. It can be said that degradable plastic packaging market has great development potential.
