Flexible packaging companies began to use benzene-free composite safety and health inks

[ppzhan Abstract] With the continuous development of environmental awareness, the printing industry is striving to transform into a sustainable development industry. The market potential of environmentally friendly and economical environmentally friendly inks is considerable. Many flexible packaging companies have now turned to the use of benzene-free composite safety and health inks.

For the printing ink industry, environmentally friendly inks are not a new term. Since the 1990s, governments have increased restrictions on hazardous emissions, and ink manufacturers have begun to provide printers with regulatory compliance alternatives, but recycling inks is bound to increase the cost of the business. The emergence of water-based inks, regrind-based pulp inks, and especially vegetable inks such as soy inks seems to have blown fresh air into the ink market. At present, although people's attention to the environmental protection of printing inks is increasing, companies are more inclined to take the path of sustainable development, such as the use of renewable resources in ink formulations.

According to the survey, environmentally friendly inks and sustainable development inks have made remarkable progress in recent years, including: improved raw materials, enabling inks to have better sustainable development while maintaining cost performance; water-based inks replacing solvent-based inks; Inks, such as HP's Latex water-based inks, provide an alternative environmental solution for existing ink products; development of thermoplastic UV inks and sustainable UV inks; development for inkjet, flexo and screen printing UV-led inks; develop radiant drying systems that provide higher line speeds, more stable humidity, lower drying temperatures and smaller equipment volumes; develop pulsed xenon lamps with more technical advantages than halogen lamps, solid state curing System and UV-LED curing systems; development of multiple inkjet, flexo and screen printing systems using UV-LED technology; development of variable sleeve offset presses to facilitate the use of UV/EB curing systems in offset printing .

From the perspective of printing technology to analyze the environmentally friendly ink market, Pila International believes that inkjet printing will achieve rapid growth in 2009-2014, with an average compound annual growth rate of 10%. As inkjet printing has become the main printing method in the signage field and has caused a sharp drop in screen printing, inkjet printing is being widely used in office tables and other fields, and gradually penetrates into the label printing market. Aqueous inks are primarily used on porous substrates, while inkjet printing relies primarily on UV inks for printing on non-porous substrates, and such applications will continue to grow in the coming years.

In the development of low-carbon economy and the promotion of green printing, the production and use of environmentally friendly safe and healthy inks has increasingly become the consensus of the ink industry and the printing industry. No matter what type of exterior is indispensable for ink printing. Safe and healthy printing inks are the key to the safety and health of plastic packaging.

At present, all food packaging, especially gravure printed plastic packaging, is printed with solvent-based inks. Solvent-based inks are organic volatiles that can cause a more severe greenhouse effect than CO2 and severely pollute the atmosphere. Despite strict requirements for solvent residues, there are problems such as damage to health and post-press solvent residues that affect the odor of foods and the safety of food. There are more or less organic solvent residues on the package. There are many kinds of residual organic solvents, such as benzene, ketone, ester, alcohol, etc., in which benzene solvent will penetrate the film in a short time to make the food in the package suffer. Secondary pollution, which causes leukemia and the like. The large-scale flexible packaging enterprises represented by Master Kong, Want Want, Wahaha and Nestle have all turned to the use of benzene-free composite safety and health inks this year.

At present, there are three main types of inks that are environmentally safe and healthy: water-based inks, alcohol-soluble inks, and UV inks. Although the market base of environmentally friendly inks may still be weak, in the future it will certainly bring valuable development opportunities to raw material suppliers, equipment manufacturers and ink manufacturers. The printing industry is striving to transform into a sustainable industry. Innovative products with environmental and economic benefits are emerging, and the market for solvent-based and petroleum-based inks is gradually being replaced by newly developed environmentally friendly products.
