New regulations for cling film, the public should pay attention to the warning on the packaging when purchasing
The new national standard for "self-adhesive plastic wrap for food plastics" has been officially implemented. In addition to PE cling film, PVC and PVDC food wrap films are included in the national standard for the first time. According to this, PVC and other plastic wrap should be marked with warning language such as “cannot be touched with greased foodâ€, “no microwave oven heatingâ€, “no high temperature useâ€. Other types of plastic wrap, such as those claimed to be heated by microwave ovens, must also indicate the heating method and maximum temperature resistance, in addition to the "can be used in microwave ovens". The public should pay attention when purchasing.
[Highlights]
PVC film should be marked "not for high temperature use"
The officially implemented national standard "Plastic plastic wrap for food" will replace the 20-year "PE self-adhesive wrap film" national standard. The new national standard stipulates that the plastic wrap that can be used for packaging food will be marked with the words “food†and the net weight of the nominal value. Preservative films such as PVC should be marked with warning language such as “cannot be touched with greased foodâ€, “not heated by microwave ovenâ€, “not for high temperature useâ€.
“This is because the PVC film contains the plasticizer DEHA, which is a kind of oil compound rather than a food additive. It can have adverse effects on the human body by heating or packaging cooked food in a microwave oven. Once it is mixed with raw meat, fried food, etc. Food contact, will be dissolved in the oil of food, endangering human health." Dong Jinshi, Secretary General of the International Food Packaging Association explained. Other types of plastic wrap are claimed to be heated in a microwave oven. In addition to the "microwave oven", the heating method and the maximum temperature resistance must be indicated.
The same is 200 meters of plastic wrap, why are some products short-lived, can not use a few days? Previously, almost all of the plastic wrap on the market was only marked with length and width, and there was no weight. Some citizens suspected that the manufacturers had done their hands and feet.
According to industry experts, the new standard not only specifies the requirements for the use of various types of plastic wrap, but also imposes stricter requirements on the material and specifications of the products. In addition to the length and width, the manufacturer is required to clearly mark the thickness and net weight of the wrap film on the package, and modify the length deviation in the original standard to the net roll weight limit deviation.

New regulations are not enforced
The reporter visited the supermarkets such as Tianhe City Jiji Island and Guangbai Zhongyi Store. I saw the variety of plastic wrap on the market. The specifications ranged from 20 meters to hundreds of meters. Most of them have been marked with warning signs according to the new national standard.
There are about 10 brands of plastic wrap in Jusco, and most of them are marked "food packaging" on the package. However, the labeling of individual products such as Miaojie is still very vague, and it is not conspicuously marked whether it can be used for heating. In addition, almost all products are only marked with "length and width", and for the net weight value, few products can be marked.
The reporter also found that the vast majority of the market is the PE film, and the PVC film gradually fades out of people's vision. Dong Jinshi, secretary-general of the International Food Packaging Association, said that PVC film used to package meat, cooked food and other foods may endanger human health. After the toxic plastic wrap in 2005, the plastic wraps currently sold in major supermarkets are basically free of plasticizers. The PE film has higher safety and is therefore used more on the market. According to industry insiders, there is also a type of PVDC cling film on the market, but the high production cost makes its application and sales not very extensive.

It is best to use less plastic wrap
Industry experts pointed out that from the perspective of environmental protection and health, the public should try to use cling film as little as possible.
“The widely used PE cling film, although it does not contain plasticizers, is a plastic product. After a long heating, there will be chemical molecules entering the food. Therefore, we recommend that the public should not use it at high temperatures, at least according to the product packaging. The specified temperature range is used, and the plastic wrap should not be in direct contact with food for a long time," Dong Jinshi pointed out. In addition, some cling film is difficult to decompose after being discarded, in order to avoid environmental pollution, it is best to use less cling film. (Source: Nanfang Daily)
