Low migration UV inks UV inks now been able to achieve without solvent evaporation, low odor and many environmentally friendly features, and is widely used in various types of food packaging printing. Although these inks are not in direct contact with food, but it really is an indispensable part of food packaging, its security is also a growing concern for all. In fact, the chemical composition of UV cured inks also exists the possibility of migration into the packaged food, which then enter the body through food, and ultimately cause harm to human health. For example, by the end of 2005, the relevant departments in Italy Nestle milk for routine detection, accidentally discovered isopropyl thioxanthone this does not exist in milk composition of harmful substances. Later identified, actually comes from the milk packaging has been cured UV inks. After that, the various components of Nestle food packaging ink devoted to the strict rules. Configuration is made using ordinary materials UV inks are often not well controlled due to their mobility, easily lead to food packaging printing inks for food contamination. Ink manufacturers by screening large molecular weight initiator, high purity reactive monomer and resin and pigment powder regulatory compliance, and control the number of migration of these substances in a small area, or even close to zero migration, actively developed a has good prospects for the development of low migration UV inks. Can predict the future provision of various types of regulations on food packaging will be more detailed, detection methods will also be more stringent, UV printing labels must need new low migration UV inks, the perfect combination of both Hengli along pit box printing, even may bring a green revolution in the field of printing. In addition to concern the ink itself "green" Hengli box printing cosmetics boxes, reducing the production process inks (especially color ink) the remaining amount of ink is associated with "green" applications. This article talks cigarette remaining ink printing process data management Hengli box printing film cassette, is gradually moving towards fine, digital label printing business management or from the lessons. The company where the author is a professional tobacco packaging design, development, production and sales of high-tech printing enterprises, the current use of offset printing ink, the loss caused by excessive residual ink is necessary to pay attention to the problem. In general, according to the needs of enterprises producing ink purchase orders, warehouse according to the first-in first-out principle ink distribution, production department and then receive ink from the offset inking room, when the end of production, the remaining ink returned to the warehouse. Enterprises in the production process in order to ensure non-stop, usually ready excess ink. And most of the UV offset ink shelf life of a year's time will soon exceed the shelf life of Hengli box printing, ink is likely to face retirement, if he insists on continuing to use, it may be a variety of uncontrollable print quality problems. Has been tuned especially for spot color inks, in order to solve the problem of its remaining ink consumption, the more difficult. According to my investigation, as of July 31, 2014, the author's company offset ink remaining amount of more than 200 tons, according to the average price of the original ink is 130 yuan / kg calculated total tens of million of ink facing obsolescence of issue. Although production through redeployment deep background, able to consume some of the remaining ink, but the process is not quantifiable management, the use of the remaining ink is also no scientific data as a basis.
