Brief Analysis of Application and Damage of Plastic Gravure Ink
2024-07-03 11:05:42
Plastic gravure inks are mainly used in food packaging, salt packaging, cosmetic daily product packaging, and pharmaceutical packaging. Food packaging is based on composite inking ink, some candy paper with table printing ink; cooking packaging using high temperature cooking ink, the general vacuum packaging is to use polyester ink; dairy packaging suitable water, acid, temperature resistant ink; Pharmaceutical packaging and cosmetic packaging are mainly based on polyester ink; some manufacturers use table printing inks, some manufacturers use composite printing inks, but more manufacturers use polyester inks; along with packaging market grades. There are more and more products that use composite inks and special special inks.
Intaglio printing inks are generally made of chlorinated polymers. In the ink production process, the chlorinated polymer needs to be dissolved using a strong solvent (such as toluene and other aromatic solvents), and the viscosity of the ink is adjusted with toluene during the printing process. Chlorofluorocarbon gases that are volatilized during the production of chlorinated polymer inks can destroy the atmospheric ozone layer. The use of aromatic solvents (toluene) in the printing process can harm workers' health and safety (fire hazards). In addition, the problem of ink solvent residue in packaging products is a concern. Benzene can easily remain in the dry ink film layer (low-speed printing requires the use of xylene to adjust the drying speed of the ink, xylene is more likely to remain), and benzene residues can contaminate the food or articles in the package. Although the gravure alcohol ester ink is the leader of the alcohol-soluble ink, although there is no benzene-free ketone, it will still pollute the environment and there will be residual solvent.
The production of plastic gravure inks is subject to laws and regulations such as Fire Protection Law, Labor Safety Law, Health Law, etc. Therefore, it is an inevitable trend to actively develop and apply water-based inks that meet the environmental protection requirements of green gravure inks.
