Can PVC plastic wrap really cause cancer

[playback] the incident alerted the Political Bureau

the continuous plastic film incident attracted the attention of relevant leaders of the Political Bureau of the CPC Central Committee. Under the high-level instructions, AQSIQ has recently organized the national special supervision and inspection of PVC fresh-keeping film

"the product quality problems found in the production and sales links should be investigated and dealt with." Pu Changcheng, deputy director of AQSIQ, said

the report of "global ban on Japan and South Korea carcinogenic cling film transit to China" that pushed "food companion" to the forefront: "PVC cling film contains carcinogens, which is relatively harmful to human body. Due to the ban in China, Japan and South Korea PVC PVC food cling film has entered China on a large scale. At present, LG, Mitsubishi and Sanrong account for nearly 80% of the domestic market." The main carcinogenic ingredient is DEHA, a plasticizer, which can increase the softness of products

China has successively formulated three processing standards for food packaging materials related to PVC fresh-keeping film. As long as the products produced according to these standards can be used for food packaging

these three standards are formulated and promulgated by the Ministry of health. According to the division of institutional functions, the new standards will be formulated by the General Administration of quality supervision, inspection and Quarantine of the people's Republic of China

[inquiry] is the carcinogenic effect of DEHA misunderstood

after verification by relevant experts of SGS-CSTC, DEHA should be "diethylhexyl adipate", rather than "ethylhexylamine" as currently referred to by many media. After investigation, "ethylhexylamine" does not belong to plasticizers, nor is it used in the plastic additive industry

Founded in 1878, SGS is headquartered in Switzerland. At present, it has more than 1000 branches and laboratories in more than 120 countries and regions, and its Chinese branches are located in Shanghai and other places

"DEHA is not the carcinogen mentioned in the current data. At present, there is no clear data indicating that DEHA can cause human cancer, so the International Institute of cancer classified it as' not classified as a human carcinogen ', rather than an absolute carcinogen. There is no information about ethylhexylamine causing cancer. However, the United States, Japan and the World Wide Fund for nature (WWF) have listed this substance as a substance that may damage the human endocrine system." SGS experts said

[investigation] PVC fresh-keeping film affects human endocrine

SGS investigation report shows that PE (polyethylene) and PVC (polyvinyl chloride) materials are usually the most common commercially available fresh-keeping films. PVC packaging film contains about 14% - 38% plasticizer. Plasticizers can change the normal function of human endocrine system, and can be harmful to some organs or offspring. Like chronic poisons, many reactions are undetectable in the short term. It mainly pollutes fish, meat, eggs and dairy products

plasticizers sneak into food mainly through packaging materials. Plasticizer concentration, storage time, temperature, food fat content and contact area will affect the amount of it into food. For example, the higher the fat content of food, the greater the interaction between the additives in the fresh-keeping film and the fat when heated. Therefore, it is convenient to carry out the next step of processing. At present, most of the fresh-keeping films on the market cannot directly package high-fat food

at present, several plasticizers that have not attracted enough attention in China include:

1 Diethyl adipate (DEHA) - mainly exists in PVC fresh-keeping film

2. Di isononyl adipic acid (Dina) - especially in fish sauce, fried meatballs and roasted meatballs packed in PVC, has the highest content

3. Alkyl phenol is widely used as plastic plasticizer, industrial detergent, pesticide emulsifier, finishing agent in textile industry, etc

4. Phthalates (PAEs) - are widely used as plasticizers and softeners for plastics, carriers of insect repellents and pesticides, additives for cosmetics, synthetic rubber, lubricants, etc., and additives for plastics and foil printing inks

5. Bisphenol A (BPA) - the plastic made of bisphenol A is used in the packaging of food and beverages due to the pulsation of current and current filtering, including optical discs, food can liners, fax paper, powder pigments, safety helmets, etc., which will reduce the number of sperm and increase the incidence rate of hormone related cancers such as testicular cancer and prostate cancer

[response] tips for consumers

under the condition that PVC fresh-keeping film cannot be completely replaced at present, experts suggest that consumers can take the following actions to ensure food safety:

1 Try to choose high temperature resistant PE fresh-keeping film instead of PVC fresh-keeping film

2. When buying food, try to identify food grade plastic packaging - when buying fresh food, the fresh-keeping film without label may be PVC fresh-keeping film

3. Try to avoid direct contact between food and fresh-keeping film, and paper packaging is recommended

4. When heating food in microwave oven, avoid using fresh-keeping film, and use special microwave oven to heat utensils

[horizontal comparison] EU legislation strictly controls

in Europe, there are very strict regulations to define the plastic wrap for different foods, and they also give special numbers to the plastic wrap. For example, the No. 4 plastic wrap used to pack ordinary meat, sausage and frozen food cannot be used to pack butter, cream and other food; The No. 1 fresh-keeping film, which can be cooked in microwave oven with petroleum asphalt penetration determination gb4509 (8) 4, can pack all food

there are special laboratories in Europe to test the safety of PVC film microwave ovens. For example, for the fresh-keeping film used in microwave oven, the most important thing is to detect whether there are harmful substances in the film into the food when the food and the fresh-keeping film are heated

recently, the relevant institutions are formulating stricter regulations -- restrictions on the use of "plasticizer" components in materials. French company limpak has launched the latest special fresh-keeping film for fatty food, which meets the standards of new European regulations

[expectation] when will the new national standard be issued

there is no reason why the safety of fresh-keeping film has attracted the attention of Chinese people. The national standard for food grade PVC products was promulgated by the Ministry of health 17 years ago. The question is whether we can require ppm level to conduct in-depth research on PVC fresh-keeping film materials, so as to formulate relevant regulations and standards to regulate their use, and rely on an effective quality and safety assurance system for long-term supervision

The PVC incident once again focuses on consumption safety and the management problems behind it. Both regulatory authorities, businesses and manufacturers should take more comprehensive and effective measures to improve the credibility of products
