Experts comment on the hazards of plastic packaging to health

Inferior food packaging can cause cancer and become a “toxin factory” when it becomes hot

Through years of research, Dong Jinshi has a thorough understanding of the safety issues behind plastic packaging. He said: "In order to reduce costs, some businesses not only add industrial paraffin, talc, calcium carbonate and other harmful substances, but also use industrial-grade raw materials instead of food-grade raw materials, and some even use waste plastics, and the source of these waste plastics is more complicated Some of them even come from medical waste or pesticide bottles. There are also some businesses that add some dark coloring agents to conceal impurities in raw materials. This undoubtedly causes hidden dangers for people's health."

In Dong Jinshi's view, if a poor-quality lunch box is filled with steamy meals, it is a miniature "toxin manufacturing field." After some inferior packaging boxes are met with acid and water, the lead, cadmium, and other heavy metals in the packaging box are easily dissolved. And these harmful substances are also easily dissolved in food. If you ingest it for a long time, it will not only lead to indigestion, but it will also lead to gallstones and liver diseases. The polycyclic aromatic hydrocarbons contained in industrial paraffins used for food packaging may even cause cancer.

Test results

20 times more than harmful substances
