As plastic packaging accounts for an increasingly larger proportion of the packaging industry, the demands on it are also becoming increasingly stringent, with environmental protection being one of the requirements. Regardless of the type of plastic packaging used, it must meet the requirements of green packaging: reducing waste pollution; addressing environmental issues related to solvents; and addressing recycling and reuse issues. Environmentally friendly and pollution-free green packaging will be increasingly valued by society. Therefore, green packaging should be vigorously developed, and efforts should be made to improve the handling of packaging waste and the recycling and reuse of resources to achieve the requirements of sustainable development.

　　In terms of raw material sources, biodegradable biomaterials have become a highlight in the packaging field. While they cannot completely replace petroleum-based plastics, their application rate is increasing year by year, thanks to government encouragement and corporate promotion. As packaging materials, especially food packaging materials, safety is the most basic principle that should be followed. How to ensure product performance while avoiding contamination of food by plasticizers, metal elements, etc., is a problem that enterprises must solve to survive and develop. Furthermore, as a member of society, enterprises must assume corresponding social responsibilities, improving the handling of packaging waste and the recycling and reuse of resources to achieve the requirements of sustainable development.

　　Biopolymer materials are mostly used in packaging and food service, mainly for packaging products intended for single use, disposal in landfills, or ocean disposal. As a result, biodegradability has become a primary consideration when choosing packaging materials. The main reason why this issue has not been given due attention for many years is that the Price of bioplastics is better than that of ordinary materials. However, according to a report from Smithers Pira, bio-based products, as sustainable and renewable raw materials, have established a firm foothold in the market, and their future will be brighter and more promising than we imagine.

　　In recent years, research and development of fully biodegradable plastics has been most active in developed countries. It is reported that in 1998, the global annual output of fully biodegradable plastics was approximately 30,000 tons. By 2001, the output in the United States, Western Europe, and Japan had increased to 70,000 tons, reaching 120,000 tons in 2004. It is predicted that before 2007, the newly launched production capacity of biodegradable polymers globally will reach 225,000 to 300,000 tons. Currently, foreign degradable products are mainly fully biodegradable plastics, which will be the long-term direction of industrial development.

　　It is understood that in 2013, the global consumption of polymer materials exceeded 650 billion US dollars. Among them, the market share of North America and Europe was less than 25%, while the market share of Asia (including Japan) reached about 40%; other regions accounted for 13%. By 2023, Asia's demand for biopolymer materials will reach 34% of the global total demand, while the market share of Europe and North America in the global biopolymer materials market will decline.
