Environmental printing ink: break through the green barriers to trade.
2015.01.13 11:06As people increasingly attention to food safety, harmful substances residues in food packaging and printing problem has become the focus of consumers. Companies pay attention to the production of green food Products at the same time, also should pay more attention to the environmental protection problem of packaging material in the printing.
Food packing printing ink: want to say it is not easy to love you
Green food consumption has become a trend, highly coordinated with them, however, a lot of green food didn't use green packaging and green printing, but instead USES some poisonous and harmful substances For the packaging and printing materials. Food packaging is referred to as "special food additives", as "close-fitting clothing" of food, its safety will directly affect the food quality. It is not difficult to find from the daily life , colourful exquisite patterns are printed on the packaging, but few people know that the ink printing design mostly benzene class material containing harmful to human body. It is understood that China's current of food packaging Mainly use solvent ink, this kind of ink contains a large amount of harmful solvents, such as benzene, toluene, xylene, benzene to exceed bid will cause cancer, especially the diseases of the blood system. In addition, the oil Ink of heavy metals such as mercury, lead, arsenic content also is great harm to human body.
Internationally recognized food printing ink must abide by the principle of free transfer; Food packaging printing on the inner surface shall not be used when conventional ink; Manufacturers must ensure that after the printing printing ink solvents in full Volatile, ink will cure thoroughly, and achieve the corresponding application industry standards. In food packaging and printing ink, therefore, the effect not beautiful.
Food packaging for environmental printing ink products?
Security printing products to form a new green trade barriers in our country. And from the point of the production process of print, ink has become a complete industrial chain must carry on the "leading role" . Now, most countries in the world advocate using environmental printing ink, alcohol soluble ink, and water-based ink, especially water-based ink as ink of green environmental protection is increasingly popularized.
Water-based ink, water-based ink is the vast majority of flexo packaging printing house at home and abroad used in printing ink, it is mainly composed of water soluble resin, organic pigments, solvents and related auxiliary by the composite grinding Work. It does not contain volatile organic solvents, not only can reduce the printing quality of residual toxicity, and can prevent fire by static contact with flammable solvents, is a new kind of "green" printing ink. water Sexual ink is also replace benzene soluble ink one of the best products. ?
The uv curing ink: the uv curing ink is mainly used in the soft base material of the flexible printing, it is composed of prepolymer, reaction diluent, pigments, additives, light initiator/composite. ?
Electron beam curing ink: most of the food and beverage packaging industry USES electron beam curing printing, the printing way for offset printing. EB ink to printing industry of the development of high speed, a multicolor printing To the. EB inks and LIV curing ink major difference is that the link if there is light initiator, when adding a certain amount of EB ink light initiator, can also be used for uv curing. EB can cure a Thick layer of ink, due to without light initiator in the ink, the cost is lower than LIV ink relatively, but the electron beam curing equipment investment is higher than LIV curing. ?
Digital printing ink: digital printing technology is as people demand for increasing personalized packaging to infiltrate in the food packaging and printing industry. Adopting digital printing technology can achieve high enough The image resolution, can perfect reproduction of the image details. Most substrates for foil, aluminum, PET polyester, paper and so on, and is suitable for printing paper.
As countries on food packaging quality safety policy tightening, environmental problems are becoming more and more important, food safety has become a global focus of attention and urgent task, and the progress of the environmental printing ink Then. In today's environmental protection consciousness gradually strengthened, people have higher requirements to the development of printing ink, ink environmental protection is the trend of The Times, our country must unswervingly green packaging and printing enterprise Development path, and can adapt to The Times development.
