Can printed materials such as newspapers or advertising papers be used to directly package food?
Most of the newspaper or advertising paper is ink. If newspaper or advertising paper is used to directly package food, it is easy to cause ink pollution.
First of all, the main pollutants in ink are heavy metals, including lead, chromium, cadmium, mercury, etc. For example, lead will hinder the formation of human blood cells and cause brain damage. In addition, the ink used in newspaper or advertising paper printing usually contains toxic organic solvents such as ethanol, isopropanol, toluene, and xylene, and the remaining part may be potentially dangerous. Finally, if you are using old newspapers, there is still a problem of spreading the virus.
