pvc fresh-keeping film has been removed from the shelves in succession.

manager Li of Zhongshan one plus one commercial chain Co., Ltd. told that they have been selling domestic fresh-keeping film all the time. At present, all of the five to six domestic brands that are selling well have passed relevant quality tests, and citizens can buy and use it with confidence

then, she dialed the spokesperson of Jizhi Island Guangzhou headquarters. She said that as soon as the company received the prohibition notice, it stopped using PVC fresh-keeping film to package cooked food, and timely contacted new suppliers to ship safe PE fresh-keeping film to Jizhi Island Branches in various cities. During the interview, the spokesman said that it was not clear for the time being whether the new batch of fresh-keeping film for packaging had arrived at the jizhidao branch in Zhongshan, but during the period, the company requested that other packaging be used instead, and PVC fresh-keeping film would never be used again

it was found in two supermarkets located in Zhongshan third road and Huabai road that the food preservative films sold by them include PE, PVDC and other kinds, and no PVC preservative film was found. The managers of the two supermarkets said that as early as more than a week ago, the supermarket had removed all PVC fresh-keeping films from the shelves to ensure safety. A secret visit to the supermarket cooked food packaging film packaging engineer Miss Li pointed out that the transparency, tensile and viscosity of PVC film are stronger than PE film. When PVC fresh-keeping film is burned with fire, the flame is black, black smoke, pungent smell, no oil dripping, and it will automatically extinguish after leaving the fire source. When PE fresh-keeping film burns, the flame is yellow, tasteless, dripping oil, and it can continue to burn after leaving the fire source. "If the label is PVC material or the material label is not clear, it is recommended that citizens use the above method to test the material of fresh-keeping film." Miss Li said. We bought five kinds of cooked foods from Zhuyuan branch of one plus one supermarket, Holiday Plaza Branch of PARKnSHOP supermarket and trust Mart Huabo branch, including salted and dried peanuts, bread, cake, corn steamed bread and roast chicken, and took them back to our office. Then, cut a 5cm square sample from the packaging material of each cooked food and ignite the sample with a lighter. It was found that the flame of the fresh-keeping film and fresh-keeping bag of the above five cooked foods was yellow, tasteless, dripping oil, and could continue to burn after leaving the fire source. According to the identification method of packaging engineer Miss Li, the packaging material of these samples should be PE

citizens calmly face the fresh-keeping film storm

it is understood that according to the current market price, the price of PE and PVC fresh-keeping film products of the same brand is different: the retail price of 20 meter long PVC fresh-keeping film in simple packaging is about 8 yuan, while the retail price of 30 meter PE fresh-keeping film in hardcover of a brand is as high as 16.9 yuan. Because the price of PE fresh-keeping film is more expensive than that of PVC fresh-keeping film, and PVC fresh-keeping film exceeds PE fresh-keeping film in terms of transparency, toughness and viscosity, smart Zhongshan housewives generally chose PVC fresh-keeping film before the PVC fresh-keeping film storm

in Zhuyuan branch of one plus one supermarket, the housewife Ms. Yuan said to her, "I probably know that the old plastic wrap at home can't be used. I don't know the English alphabet, so I asked my son to buy a new roll of plastic wrap." Ms. Cai, who was about to enter the Zhuyuan market to buy vegetables, said, "I seldom use plastic wrap at home, and I'm not used to buying cooked food in the supermarket. My daughter pays attention to environmental protection, and the food put in the refrigerator will be packed in stainless steel lunch boxes."

PVC films produced according to the national standard are safe

it was learned from relevant departments that the Ministry of health of the people's Republic of China made it clear that PVC fresh-keeping films produced according to the national standard of food packaging materials in China are safe in response to the "cancer causing PVC fresh-keeping films" highly concerned by the media recently

the so-called "toxic" problem mainly comes from the fact that the residual vinyl chloride monomer that may cause cancer in PVC exceeds the national standard, or the use of processing aids prohibited for food packaging materials. According to the standard formulated in 1988, the indicators for controlling vinyl chloride monomer are consistent with international standards. The standard stipulates that the content of vinyl chloride monomer in food packaging materials per kilogram must be less than 1.0 mg

according to Miss Li, a packaging engineer, PVC is a hard plastic. To pull it into a transparent and soft fresh-keeping film, a large amount of plasticizer must be added. The main component of plasticizer for PVC fresh-keeping film is ethylhexylamine, which is a substance added to synthetic resin materials to increase the flexibility and elasticity of products. The content of plasticizer in PVC fresh-keeping film is about 40% to 5, so as to seize the commanding height of industrial development 0%. This substance is easy to release when encountering grease or high temperature. With food brought into the human body, it is easy to cause endocrine and hormonal disorders, and there is a risk of cancer, causing great harm to the human body

little dictionary


that is, PVC. PVC is widely used in production and life. Such as PVC water pipes, PVC plastic doors and windows, and plastic toys containing PVC. The potential harm of PVC to human body mainly comes from two aspects: the residue of vinyl chloride monomer in products exceeds the standard; The type and content of processing aids used in the processing process do not meet the relevant standards. The research team conducted coherent load experiments in an empty laboratory

[types of preservative films]

food preservative films are divided into polyethylene (PE), polyvinyl chloride (PVC), polyvinylidene chloride (PVDC) and other types according to their materials. PE and PVDC are safety materials


that is, ethylhexylamine, a low volatile liquid, is often added to synthetic resin materials as a plasticizer to increase the flexibility and elasticity of products. The content in PVC fresh-keeping film is about 40% to 50%
