According to the Regulations on the Administration of Production Licenses for Industrial Products, from September 1, the quality supervision department will investigate and punish all acts of producing, selling or using paper products without the certification of production license for food paper packaging, containers and other products. With the increasing emphasis on food safety, the problem of excessive residues of harmful substances in food packaging printing has become the focus of consumer attention. People call on enterprises to pay attention to the production of green food at the same time, should also pay attention to packaging materials in the printing of environmental protection issues.

Green food consumption has become a trend, but it is very inconsistent with it, many green food does not use green packaging and green printing, but use some toxic and harmful substances as packaging and printing materials. Food packaging is known as "special food additives" as food "close-fitting clothing", its safety will directly affect the quality of food, unqualified food packaging in the use of the process will have a negative impact on human health, especially on the well-being of children and adolescents have a major security risk. In daily life, it is not difficult to find that many dealers in order to attract the attention of consumers, in food packaging printed with colorful delicate patterns, but few people know that the printing ink mostly contains harmful to human body benzene substances.

Zhang Liming, deputy director of the National Printing and Decoration Quality *** Inspection Center, said that China's food packaging is mainly using solvent-based ink, which contains a large number of harmful solvents, such as benzene, toluene, *** and so on. If benzene exceeds the standard, it will cause cancer, especially blood system diseases. In addition, heavy metals in the ink, such as mercury, lead, arsenic and so on, also pose great harm to the human body.

It is internationally recognized that the ink used in food printing must abide by the principle of non-transfer; the conventional ink must not be used in the inner surface printing of food packaging; the printing manufacturer must ensure that all the solvent in the ink after printing is volatilized, and the ink requires thorough curing, and meets the corresponding standards of the application industry. This shows that the role of ink in food packaging and printing can not be underestimated.

The safety of printed matter will form a new trade green barrier to our country. From the point of view of the production process of printed matter, ink has undoubtedly become the "protagonist" in this complete industrial chain. At present, most countries in the world advocate the use of environmentally friendly inks, alcohol-soluble inks and water-based inks, especially water-based inks as green inks are more and more widely used.

With the tightening of national policy on food packaging quality and safety, environmental protection is becoming increasingly important. Food safety has become the focus of global attention and an urgent task, and has become the development criteria of environmental-friendly ink. In today's increasingly environmental awareness, people have higher standards for the development of ink, ink environmental protection has become a general trend, China's packaging and printing enterprises must persistently take the road of green development, in order to adapt to the development of the times.
