PVC cling film can not pack food can also play what role

On July 28, CCTV's "Weekly Quality Report" revealed that 15 kinds of PVC (polyvinyl chloride) cling film have 15 kinds of banned plasticizer DE-HA. The survey also found that half of supermarket cooked food packaging uses PVC cling film. Experts said that the plastic wrap destroyed the body's endocrine system and reproductive system, leading to female precocious puberty and male infertility. To this end, experts have reminded consumers that it is best to use PE ( polyethylene ) cling film.

PVC, PE plastic wrap how to distinguish

As a commonly used food packaging material, cling film has become a must-have item for urban families because of its convenience. Because the PVC cling film has high transparency and good adhesiveness, it has a relatively large market share. After visiting some supermarkets in Taiyuan City, the reporter found that in all types of cling film, PVC cling film accounts for about 60% to 70% of the market share due to its low price. Moreover, many supermarket salesmen said they did not know what kind of cling film they used.

Many attentive citizens have discovered that after a few days from the meat cooked food bought from the supermarket, there is a layer of oily things on the outer layer of the insurance film, unlike the oil itself. According to investigations, this cling film is a PVC cling film.

According to relevant experts, PVC plastic cling film will add a large amount of plasticizer during the production process. Plasticizers are insoluble in cold water, but they will precipitate out at or above 60 degrees Celsius, or in oils and fats, especially in vegetable oils. Therefore, the undiscovered fat-like substances discovered by the public are likely to be plasticizers contained in plastic wrap.

Moreover, the nationally banned DEHA can be released from plastic wrap at room temperature and permeate into food, especially when it is packaged in foods with higher fat content. The main hazard is affecting hormones, leading to disruption of the endocrine system. The main phenomenon is that some estrogen secretions will increase and the secretion of male hormones will decrease, which will have a great influence on infants' genital development.

It seems that consumers are best to use PE cling film. If you use PVC cling film, it is best not to directly use for packaging meat, cooked foods, and foods containing oil, but also should not be directly heated in a microwave oven.

So, how to identify PVC cling film and PE cling film? The manager of a large supermarket in Taiyuan taught the reporter three tricks: First, look at the colors. The yellow color of the entire roll is PVC and the white is PE. Second, rub your hands. PE cling film is generally less viscous, easy to open after hand rub, and PVC cling film is sticky, easy to rub the hand to start. In addition, you can try to burn it. After the PE cling film is ignited by the fire, it will burn quickly and will not extinguish when leaving the fire source. However, the PVC cling film is not easy to ignite and will extinguish after leaving the fire source and has a pungent odor.

The beachside community Wang Auntin has a coup to kitchen cleaning. “As soon as the Chinese New Year approached, the families of all households would ask people from home management companies to come to the door, mainly wiping the hood and wiping the tiles in the kitchen. All of them were oily, and they got into trouble. My family didn’t have to ask for housekeeping, because I usually stay in the kitchen. In the cooking stoves, some plastic wraps are attached to the side of the cooker hood, while the cooking fumes are not only part of the range hoods, but also a lot of them are still spinning in the kitchen, the top of the cooking table is the most concentrated, and the plastic wrap is attached.
