Plastic products have been involved in all aspects of our lives, but do you know how many plastics there are? Under what circumstances will plastic products produce any kind of harm? Liu Lifang, member of the CPPCC National Committee and secretary of the Party Working Committee of Guilin Street in Zhongshan District of Dalian, said that the emergence of plastic products has provided convenience for the people's lives, and it has also caused great harm to the environment. 7 plastic labels indicate their respective uses When people use plastic bottles under different conditions, they do not know enough about the harm caused by human body. Most of the plastic bottles we use every day are made of high-density polyethylene, polyvinyl chloride, low-density polyethylene, polypropylene, polystyrene and other chemical products. Manufacturers have different labels when using these items, namely 1, 2, 3, 4, 5, 6, and 7. Each label has a triangular symbol with an arrow on the outer ring. PET No. 1 is a common mineral water bottle that is easily deformed by heat resistance to 70 °C. The carcinogen DEHP may be released after the first bottle is used for 10 months. HDPE No. 2 is a common medicine bottle, cleaning products, and bath products. It cannot be used as a storage box for drinking water, and it cannot be recycled. No. 3 PVC common raincoat, building materials, plastic film, plastic box, etc., do not recycle or package food. No. 4 LDPE common plastic wrap and plastic film can release toxic substances when exposed to high temperature. It can cause breast cancer, congenital defects and other diseases after entering the human body with food, and can not put the plastic wrap and food into the microwave oven. No. 5 PP common soy milk bottle, yogurt bottle, juice drink bottle, microwave lunch box, etc., melting point up to 167 ° C, can be carefully cleaned and reused, some microwave lunch box box is made of No. 5 PP, but the lid is Made of No. 1 PE. Since the PE cannot withstand high temperatures, it cannot be placed in the microwave oven with the box. 6th PS common fast food box, instant noodle box, can not be placed in the microwave to heat, but can not be loaded with acid, such as orange juice, alkaline substances, can not hold hot food, so as not to release carcinogens. PC No. 7 has a kettle, a space cup, a bottle, etc. These plastic products cannot be exposed to sunlight, can not be heated, and can not be poured into boiling water, which can release carcinogens after being heated. No. 1 plastic products are frequently contacted and used by some people. Some people do not know this knowledge. They use mineral water bottles to hold cooking oil and other seasonings. Repeated use can lead to cancer incidence. The most toxic plastic containers of No. 3, No. 6, and No. 7, using these bottles to load food are more harmful to the human body. Ultra-thin plastic bags are still popular in the farmers market Liu Lifang pointed out that there is also an ultra-thin plastic bag with no logo. Since June 1, 2008, the state has ordered the major supermarkets and the morning market and the night market to ban the use of ultra-thin plastic bags for free. . However, from September to October of the year, many morning and night markets in the city, the use rate of ultra-thin plastic bags is 100%. In addition, the use of plastic bags with QS marks for cooked foods is not optimistic. From January 1, 2008, according to the stipulations of the General Administration of Quality Supervision, Inspection and Quarantine, China has imposed a mandatory entry system for plastic products for food. However, in Dalian, except for large supermarkets, raw and cooked foods are packaged in food plastic bags. In the farmer's market, as well as in the streets and alleys, the food stalls around the school can be seen everywhere. The steamed buns and steamed buns, cooked meat products that have just been cooked and cooked, are packed with no QS logo and odor. The phenomenon of ordinary white plastic bags produced by small family workshops. These white plastic bags without QS mark are mixed with recycled plastics, and most of the recycled plastics are synthesized from recycled plastic waste or even medical infusion needles. The main component of PVC is a toxic chemical raw material. When it comes to acidic and oily substances, especially when it comes to cooked foods with higher temperatures, the harmful substances are easily absorbed by food and enter the eater. Long-term use of plastic bags made of recycled plastic packaging foods can easily lead to chronic food poisoning and central nervous diseases. It is recommended to strengthen management from the source Liu Lifang suggested starting from the source, strengthening supervision of plastic bag manufacturing enterprises, and completely withdrawing ultra-thin plastic bags from production. At the same time, strengthen the environmental awareness of market managers, increase management and supervision, conduct spot checks from time to time, and resolutely ban hawkers who do not listen to dissuasion. From the food handlers, plastic bag producers and other means to cut through, increase the enforcement of enforcement of food plastic products access system, especially increase the mandatory use of QS mark food plastic bag packaging law enforcement efforts to ensure that The quality and safety of the whole cooked food packaging in Dalian. Adhere to long-term public opinion propaganda, call on the public to use all kinds of plastic products correctly, and consciously use environmental protection bags to fundamentally resist the use of ultra-thin plastic bags.
