In recent years, with the rapid development of China's economy, people's pursuit of material and spirit is getting higher and higher, and the packaging of products has correspondingly higher requirements. When people buy products, they not only look at the beauty of the outer packaging, but also consider a variety of other functions to make it more convenient to use. Traditional plastic bags lead to more and more serious white pollution, people are also in the pursuit of product packaging continues to improve, many new green packaging materials continue to be applied to product packaging. Synthetic polymer materials have the advantages of light weight, high strength, good chemical stability and low price, and steel, wood, cement has become the four pillars of our economy, and is widely used in product packaging.

However, while synthetic polymer materials bring convenience to people's lives and improve the quality of life, a large amount of derived waste after its use is also increasing, becoming a white source of pollution, seriously endangering the natural environment, causing groundwater and soil pollution, endangering human survival and health, and causing a negative impact on the environment on which human survival can not be ignored. In addition, the production of synthetic polymer materials of raw materials oil is always exhausted one day, therefore, to find new environmentally friendly materials, the development of non-petroleum-based polymers is imminent, and biodegradable plastic bags are one of the effective ways to solve this problem.

Non-degradable public plastics Plastic harm to the Earth's environment:

(1) Two centuries to rot. Plastic bags buried in the ground will take about two hundred years to rot, will seriously pollute the soil; If incineration is adopted, harmful smoke and toxic gases will be produced, which will pollute the environment for a long time.

(2) Degradable plastics are difficult to degrade. The common "degradable plastic bags" on the market, in fact, just add starch to the plastic raw materials, landfill because of the fermentation of starch, bacterial decomposition, large plastic bags will be broken down into small or even invisible fragments. This is a physical degradation that does not actually fundamentally change the chemistry of the plastic product.

(3) Affect the normal respiration of the soil. The plastic bag itself is not one of the basic materials of soil and water, forced into the soil, due to its own impermeability, will affect the internal heat transfer of the soil and the growth of microorganisms, thus changing the characteristics of the soil. The accumulation of these plastic bags over a long period of time will also affect the absorption of nutrients and water by crops, resulting in crop production.

(4) Easy to cause animal ingestion. Plastic bags discarded on the ground and on the water are easy to be swallowed by animals as food, and plastic bags can not be digested in the animal's stomach and intestines, which can easily lead to animal body damage and death. Therefore, more and more biologists advocate the development and application of degradable plastics, and see it as an ideal way to solve this world problem. At present, developed countries in the world are actively developing degradable plastics, and developed countries such as the United States and the United Kingdom have successively formulated laws and regulations to restrict or prohibit the use of non-degradable plastics.

The emergence of biodegradable plastic bags not only expands the function of plastics, but also alleviates and inhibits environmental contradictions to a certain extent, and is also a supplement to petroleum resources, but also shows the power and prospect of biotechnology and alloying technology in the field of plastic materials from the synthesis technology, and its development has become a hot spot in the world's research and development.

Biodegradable plastic bags have their advantages over traditional plastic bags in terms of performance, practicality, degradability and safety.

In terms of performance, biodegradable plastic bags can reach or exceed the performance of traditional plastic bags in some specific areas;

In practical terms, biodegradable plastic bags have similar application performance and hygiene performance with similar traditional plastics.

In terms of degradability, biodegradable plastic bags can be quickly degraded in the natural environment (specific microorganisms, temperature, humidity) after use, and become fragments or non-toxic gases that are easy to be used by the environment, reducing the impact on the environment.

In terms of safety, the substances generated or remaining in the degradation process of biodegradable plastic bags are harmless to the environment and will not affect the survival of humans and other organisms.
