According to "industrial production permit regulations" requirement, since September 1, the quality supervision departments will be fully investigated without the Food Paper packaging, container production permit certification, and in the production, sale or use of paper products in the behavior. As people's increasing attention to food safety, food Packaging Printing Excessive residue of harmful substances in question has become the focus of consumer concern. It called for the production of green food enterprises in focus, but also should pay attention to the printing of packaging materials Environmental protection Problem.
Ink as food packaging safety hazards
Green food consumption has become a trend, but with a very uncoordinated, many did not use green packaging green food and green printing, but the use of toxic and hazardous substances as packaging and printing materials. Food packaging is known as "special food Additive "As food" personal clothing "will directly affect their security of food quality, substandard food packaging in the course of adverse effects to human health, particularly the health of children and adolescents will be a significant security risk development . everyday life,
In which we can easily find many dealers in order to attract the attention of consumers in the food packaging printed with colorful designs exquisite, but very few people may know, most printing ink pattern of benzene containing harmful substances .
National print decoration products Quality Supervision, Inspection, said Zhang Liming, deputy director, China's current food packaging is mainly used solvent-based inks, these inks contain a large number of harmful solvents, such as the benzene, toluene, xylene, benzene exceeded, then the causes cancer, especially haematologic diseases. In addition, the ink of heavy metals such as mercury, lead, arsenic in the soil there is great harm to the human body.
Internationally recognized food and printing ink must adhere to the principle of free transfer; food packaging materials shall not be used when the inner surface of conventional ink printing; printing after printing ink manufacturers must ensure that all evaporation of the solvent, ink requires curing completely, and to apply corresponding industry standards. Thus, food packaging printing ink in the role of non-small-Liang.
Food packaging appeal to environmentally friendly ink products
Security printing products, China will create new barriers to trade in green. Print production process from the point of view, this ink is no doubt a complete industry chain must mention the "hero." Now most countries promote the use of environmentally friendly inks, alcohol soluble ink and water-based ink, in particular water-based ink green ink as more and more been spread.
Water-based ink: Ink is water-based flexographic packaging printing at home and abroad most of the ink used, it is mainly water-soluble resins, organic pigments, solvents and related additives made by the combined grinding. Water-based ink water soluble resin is a link to material, often used internally to link water soluble acrylic resin modified material, its heat resistance, weather resistance, chemical resistance, resistance to pollution and will have great gloss, a significant advantage, either directly dispersed or dissolved or synthetic polymer latex, have shown excellent performance, water-based ink does not contain volatile organic solvents, not only can reduce the toxicity of residual print product, and can prevent static electricity and flammable solvent contact fire, is a new "green" printing ink. Water-based ink is the best alternative to benzene soluble ink products.
UV curing ink: UV curing ink is in a certain wavelength of UV light exposure, the ink feed links crosslinking reaction occurred, from a liquid into a solid complete curing of the ink, before it dissolved in the link material, large prepolymer molecules to form the solid ink film. UV curing ink is mainly used for soft, flexible printed substrate, which consists of prepolymers, reaction diluents, pigments, additives, photoinitiator / compound composition.
Electronics Beam curing ink: E-beam curing ink is in the high-energy electron beam irradiation can quickly change from a liquid into a solid ink, also known as EB ink. Most food and beverage packaging industry, e-beam curing printing, printing to Offset printing .
