Toxic plastic bags are generally colorful or white, but have poor transparency, are turbid, and have uneven stretching and small particles on the plastic surface.

Authoritative information

"According to relevant national regulations, waste plastic can be recycled, but there are strict technical requirements. Previously, I have also conducted investigations and analyses. Some of the plastic products currently used for food packaging on the market have problems with the source of raw materials, and some are waste materials and recycled materials that do not meet the requirements of food packaging."

Recycled plastic cannot be used for food packaging

Dong Jinshi said that the country has clear regulations on the application scope of recycled plastic products. They cannot be directly used to make items that come into contact with food. They can only be used to make products such as garbage bags and chairs. All waste plastic cannot be used as food packaging materials. Because the plastic used for food packaging have strict standards and must be non-toxic, they are generally made of raw materials such as polyethylene, polypropylene and melamine. These raw materials do not need to add chemical additives during processing, and the composition is relatively stable and single, so even if they are used to hold high-temperature food or water, no harmful reactions will occur. Good plastic raw materials come from specialized petrochemical plants and meet hygiene requirements.

Even so, different raw materials must be selected according to food grade and industrial grade. Industrial grade raw materials cannot be used in the production of food grade products. As for those dirty waste plastic products, some of them can still see impurities melted in the plastic, and they cannot be used to make food grade plastic products. But in actual operation, some producers and operators know that they are garbage plastic raw materials, but they sell them to the outside without any labeling.

Not only are the production raw materials worrying, but the production environment of some factories is also very unhygienic. "At present, all plastic packaging for food is implementing QS market access certification. The dirty and messy production environment of those black dens cannot meet the hygiene requirements of food packaging production at all. However, some manufacturers only consider profits and ignore their social responsibilities, and produce a large number of products that are harmful to consumers' health." Dong Jinshi said, "This situation is related to the lack of supervision and investigation by relevant functional departments." Experts say "Waste plastic contain a large amount of corrupt and deteriorated components, bacteria and harmful chemicals. Some people think that these plastic products are melted at high temperatures during the production process, and high temperatures have the effect of disinfection and sterilization, but in fact this is a misunderstanding." "Toxic plastic" are more harmful than gutter oil Dong Jinshi Shi said, "High temperature only works on common E. coli. Some bacteria and viruses cannot be killed by high temperature, and these plastic products are generally made in underground processing plants or small workshops with extremely poor sanitary conditions. Mixing them together can easily cause secondary pollution. In addition, waste plastic often contain heavy metals including lead stearate. These harmful substances enter food packaging materials and then enter the human body with food or beverages. Over time, they will cause considerable harm."

Consequences

At the same time, due to the rough processing level, most plastic granule manufacturers are unable to carefully distinguish between polyethylene and toxic polyvinyl chloride, and the granules produced by mixing them together are undoubtedly toxic, and the various plastic products made from them have become "poisons." In addition, "waste plastic have low purity and will produce a large amount of styrene during the production process, which is harmful to human health. In severe cases, it may also affect female fertility and cause cancer." Dong Jinshi said that since food packaging bags produced from waste plastic contain high levels of harmful substances and have long contact time with food, long-term use of plastic bags made of recycled plastic to package food can easily lead to chronic food poisoning and central nervous system diseases. Dong Jinshi believes that "long-term use of plastic bags made of recycled plastic to package food is far more harmful to the human body than 'gutter oil'."
