Degradable plastic bags (that is, environmentally friendly plastic bags) are made of polymer materials such as PLA, PHAs, PBA and PBS. Non-degradable traditional plastic bags are made of PE plastic. 2. Degradable plastic bags with different production standards must meet the national standard GB/T2 166 1-2008, which has reached the environmental protection standard. Traditional non-degradable plastic bags do not have to meet this standard. Environmental protection plastic bag production equipment includes plate making equipment, blow molding machine (also known as film blowing machine), plastic printing machine (including gravure printing machine, flat printing machine, roller printing machine and screen printing machine), laminating machine and plastic bag making machine (generally divided into two types: cutting and ironing machine and hot cutting machine); The supporting equipment for the production of environmentally friendly plastic bags are: mixer, sampler, punch, punch, baler, granulator and granulator. The annual output of plastics in China is 30 million tons and the consumption is more than 6 million tons. If plastic bags are calculated as 0/5% of plastic waste/kloc-every year, the world's plastic waste150,000 tons, China's100,000 tons, and the proportion of waste plastics in garbage accounts for 40%. So a lot of waste plastics are buried underground as garbage, which undoubtedly brings greater pressure to the already scarce cultivated land. Plastics not only bring convenience to people's lives, but also bring irreparable trouble to the environment. People call the disaster that plastics bring to the environment "white pollution". Recently, the Shanghai Municipal Development and Reform Commission and the Municipal Bureau of Ecology and Environment jointly issued the "Implementation Plan for Further Strengthening Plastic Pollution Control in Shanghai". On the morning of September 29th, a news briefing was held in Shanghai to introduce the contents of the implementation plan. Plastic products prohibited or restricted include: plastic shopping bags, disposable plastic tableware, hotel disposable plastic products and express plastic packaging. As far as disposable plastic tableware is concerned, it is required that by the end of 2020, non-degradable disposable plastic straws will be banned in the catering industry in the city. Non-degradable disposable plastic tableware is prohibited in catering service. By the end of 2025, the consumption intensity of non-degradable disposable plastic tableware in the field of food and beverage take-out in the city will drop by more than 30%. It is stipulated that by the end of 2020, the use of non-degradable disposable plastic straws is prohibited in the catering industry nationwide. From June 5438 to June 2020 10, the National Development and Reform Commission and the Ministry of Ecology and Environment issued the Opinions on Further Strengthening the Control of Plastic Pollution, stipulating that by the end of 2020, non-degradable disposable plastic straws will be banned in the catering industry throughout the country. On June 30, 2020, McDonald's China announced that from now on, nearly 1,000 restaurants in Beijing, Shanghai, Guangzhou and Shenzhen will take the lead in stopping using plastic straws, and at the same time fine-tune the design of cup lids. Non-degradable disposable plastic tableware is prohibited in catering services in built-up areas and scenic spots of cities above prefecture level. Before the end of 2022, non-degradable disposable plastic tableware is prohibited in catering services in built-up areas and scenic spots in counties. By 2025, the consumption intensity of non-degradable disposable plastic tableware in the field of food and beverage takeout in cities above prefecture level will drop by 30%. By the end of 2025, the use of non-degradable plastic bags will be banned in the markets in the above areas. Encourage qualified places to stop using non-degradable plastic bags in urban-rural fringe, urban and rural markets.
