Some technicians have been compressed to research and development similar to his institution. These degradable materials are widely used in plastic bags. In a theoretical sense, only plastic bags produced with such raw materials can be regarded as truly degradable and completely environmentally friendly. 

At present, in Shanghai, plastic bags made of corn starch, D2W, EPI and other biodegradable materials can be customized, which does not pollute the environment and harm the human body. Although there are currently fully degradable plastic bags developed, the production cost far exceeds today's costs, so this completely degradable plastic bag is called Lv in plastic bags.

The degradability of plastic bags has always been a problem.The main ingredient of yogurt is lactic acid, and polylactic acid is produced from lactic acid as a raw material, which is a purely natural biological product. will talk about this 'luxury' plastic bag., Ltd. It means that after degradation, the material molecules no longer have the characteristics of China Flexible Packaging Film manufacturer plastic, and they become substances that can be digested by the soil without causing damage to the environment.

And this is just one kind., the company conducts plastic bag research on 5% of its turnover each year. Plastic bags are truly degradable, that is, full degradation, that is, decomposition in the chemical sense. Whether any new technology is developed and popularized, can it be marketed and recognized by the public, there is an important measure of whether it, as a substitute, has the quality of the substitute. department.

For example, it is extracted from pure natural organisms such as corn, potatoes, and sugar beets and customized in Shanghai. At present, our country uses a substance called polylactic acid (PLA)
