In recent years, with the rapid development of economy, people’s pursuit of material and spirit is getting higher and higher, and there are correspondingly higher requirements for product packaging. When people buy products, they not only look at the aesthetics of the outer packaging, but also Various other functions are also considered. The white pollution caused by traditional plastic bags is becoming more and more serious, and people are constantly improving the pursuit of product packaging. Many new green packaging materials are constantly being applied to product packaging. Synthetic polymer materials have the advantages of light weight, high strength, good chemical stability and low price, and are widely used in the packaging of products as the four pillars of the national economy alongside steel, wood and cement. However, while synthetic polymer materials bring convenience to people’s life and improve the quality of life, a large amount of waste after their use is also increasing day by day, becoming a source of white pollution, seriously harming the environment, causing groundwater and soil pollution, and endangering human survival and health. , causing a negative impact on the environment on which human beings depend that cannot be ignored. In addition, the raw material petroleum for the production of synthetic polymer materials is always exhausted. Therefore, it is urgent to find new environmentally friendly materials and develop non-petroleum-based polymers, and biodegradable plastic bags are an effective solution to this problem.
