What material is PVC? Is it really carcinogenic? Weng, director of the National Plastic Products Supervision and Inspection Center, said that the materials of fresh-keeping molds on the market are generally divided into PE and PVC. PVC is a hard plastic. To make a transparent and soft plastic wrap, a large amount of plasticizer must be added. The main component of plasticizer for PVC cling film is ethyl hexylamine (DEHA), which can increase the flexibility and elasticity of products when added to synthetic resin materials, and its content in PVC cling film is about 40% ~ 50%. This substance is easy to release, and eating with food may cause cancer, especially endocrine and hormonal disorders, which are very harmful to human body. However, the staff of the National Plastic Products Supervision and Inspection Center also said that it is hard to say whether PVC cling film will cause cancer.
There are generally three ways to buy safe plastic wrap, namely, "look, touch and burn".
Look: Is there a product description? If you wear PE plastic wrap or polyethylene plastic wrap, you can use it with confidence.
"Hand feeling": PVC cling film has good transparency and viscosity, and it is not easy to spread after rubbing with hands, and it is easy to stick to hands.
"Burning": After the PE cling film is ignited by fire, the flame is yellow, and it will not go out when it leaves the fire source, with oil droplets and no pungent smell.
Experts say that whether it is PVC or PE plastic wrap, consumers can't distinguish it by naked eyes and touch. Consumers can only judge by the material label on the plastic wrap package.
The argument that PVC cling film may cause cancer may be because chlorine gas will be released when encountering high temperature, which will pollute food and cause harm to human body. Some consumers like to heat food with plastic wrap at high temperature, which is not desirable. When it is heated with food in the microwave oven, the plasticizer (DEHA) contained in PVC products may seep out. After eating DEHA, it will interfere with human endocrine, disturb human hormones, and also cause female breast cancer, newborn birth defects, mental illness and so on. Consumers can take the food out of the packaging bag as soon as they get home, cut off the surface of the food and throw it away; Food is packed in ceramic bowls. If it is covered with plastic products, be careful not to touch food, especially when cooking or heating in the microwave oven. Don't let food touch any plastic film. Thanks for adoption
