People should be alert to the printing of ink for fast food packaging

In KFC, McDonald's and many other fast-food restaurants, the staff responsible for ordering meals will put a few napkins under the fries in order to prevent the fries from directly contacting the trays. However, most consumers, after they have fries, are used to removing napkins under the fries. In the process, most fries come into direct contact with the trays, which is not very hygienic.

It is not difficult to observe carefully that there is a prompt in the lower right corner of the KFC tray paper “Please do not put food directly on the tray pad”. This prompt is printed in white ink, but the font is very small, and the tray paper Compared with the slogans on the show, it is very unobtrusive. However, the security risks here should not be ignored by us.

As far as I know, printing inks on the surface of trays and most fast food packaging boxes contain benzene as a toxic substance. Benzene is a chronic poison. If customers take too much into the body, they will damage the hematopoietic function of the body and cause chronic diseases. Poisoning. Even environmentally friendly inks that do not contain benzene may contain certain harmful substances. Because many components of the ink are oil-soluble, the substances in the ink are easily dissolved in the fried food. When the consumer eats, toxic substances are brought into the body. Therefore, consumers are reminded that it is best not to place the food directly on the printed tray paper or the packaging box.
