With the increasing proportion of plastic packaging in the packaging industry, the requirements for it are also higher and higher, green environmental protection is one of the requirements. No matter what kind of plastic packaging is used, it must meet the requirements of green packaging: reduce waste pollution; solve the environmental protection problems of solvents; recycle and reuse problems. More and more attention will be paid to green packaging which meets the requirements of environmental protection and pollution-free. Therefore, we should vigorously develop green packaging, do a good job in the treatment of packaging waste and recycling of resources, to achieve the requirements of sustainable development.

In the source of raw materials, biodegradable biomaterials have become a bright spot in the field of packaging. Although they can not completely replace petroleum based plastics, the proportion of applications is increasing year by year with the encouragement of national policies and the promotion of enterprises. As packaging materials, especially food packaging materials, safety is the most basic principle that should be followed. How to ensure the performance of products and avoid the pollution of plasticizer and metal elements to food is a problem that enterprises must solve to survive and develop. Thirdly, as a part of the society, enterprises must undertake the corresponding social responsibility, pay attention to the packaging waste treatment and recycling of resources, to achieve the requirements of sustainable development.

Most of those materials are intended to be used in fields such as marine waste packaging or waste disposal and waste disposal. In this way, biodegradability has become a factor that people first consider when choosing packaging materials. The main reason why this problem has not been taken seriously for many years is that bioplastics are more expensive than ordinary materials. But from Smithers. According to the report of Pinot company, biological products, as a kind of sustainable and renewable raw materials, have established a firm foothold in the market, and its future will be brighter and better than we think.

In recent years, the research and development of fully biodegradable plastics is the most active in developed countries. It is reported that the annual production of fully biodegradable plastics was about 30000 tons in 1998. By 2001, the output of the United States, Western Europe and Japan had increased to 70000 tons, and reached 120000 tons in 2004. It is predicted that the global production capacity of biodegradable polymers will reach 225000-300000 tons before 2007. At present, the main degradation products in foreign countries are completely biodegradable plastics, which will be the medium and long-term industrial development direction in the future.

It is understood that the global consumption of polymeric materials has exceeded US $650 billion in 2013, of which the market share of North America and Europe is less than 25%, while that of Asia (including Japan) is about 40%; the market share of other regions is 13%. By 2023, the demand for biopolymeric materials in Asia will reach 34% of the total global demand, while that of Europe and North America will reach 34% of the total global demand The global market share of biopolymeric materials will decline.
