[China Packaging Network News] In recent years, the pollution caused by the packaging and food industry has become increasingly important. Due to the fact that there is no ink that can be consumed in China at present, direct contact with food is indispensable, and the risk of ink penetrating the packaging is more difficult to find.
Scene: Citizens ignore ink contamination
China Packaging Network reporters saw many fast food restaurants, and many people have the habit of pouring food onto the plates. In a “foreign fast food†near the company, a group of high school students poured french fries and ketchup on paper. However, the China Packaging Network reporter found that printed a small line of words on the tray paper: "This tray of paper is a common print, can not be in direct contact with food."
Dong Jinshi, vice president of the International Food Packaging Association, said in an interview whether ink migration will occur with food, packaging materials, and ink itself. "If the food is oily, the ink can easily penetrate the package into the food." He said that the other is the penetrability of the packaging materials, in general, the use of multi-layer composite film will be a little better, such as paper-plastic composite , aluminum plastic composites and so on.
Hazard: Ink or toluene and lead
Zhang Liming, deputy director of the National Quality Supervision and Inspection Center for Printing and Decorating Products, pointed out that once the inks and their harmful substances in food packaging are relocated, they may cause toluene, lead and other harmful substances in the food.
“At present, there are no edible inks in China.†Dong Jinshi said that 80% of domestic inks contain benzene solutions, and benzene solutions are carcinogenic. Even with environmentally friendly ink that does not contain benzene, the ink itself cannot directly contact the food. Dong Jinshi believes that it is very difficult for the average consumer to distinguish the packaging itself from the migration of ink. “So I called for companies that use benzene-free green ink to be labeled on the packaging and used as a reference for consumers to purchase.â€
