In Europe, especially in Germany, toluene-like aromatic solvents have been banned for food packaging inks. Similar to Europe, the United States has stricter environmental laws to control the release of volatile organic compounds. This has prompted polymer and ink chemists to develop more environmentally friendly products for food packaging inks. Although water-based gravure inks have attracted attention as an alternative to toluene-based inks, printability and quality still fall short of the standard for solvent-based gravure inks. This is mainly due to the higher surface tension of the water, which makes the ink difficult to wet and dry slowly.
In order to use the water-soluble ink in the gravure printing press, not only the ink and the resin require advanced technology, but also the gravure printing apparatus needs to be improved, such as changing the depth of the approximately 38-42 micron resist roll to the groove depth of about 24-38. Micron laser platemaking cylinders also require more effective and powerful drying equipment and drums, pumps, and other components made of corrosion-resistant materials, so they are not currently available. The water-based flexographic printing inks currently used in the market are mainly used for the printing of paper and corrugated paper. The quality requirements are general and relatively easy to accept. They are widely used in Europe and America.
Since water-based gravure inks are not yet fully capable of replacing toluene inks, the ink industry has been working hard to develop environmentally acceptable alcohol-soluble inks. Alcohol-soluble ink can solve the health problems caused by toluene ink and solvent residue affect the quality of packaged food and other issues. In Europe and the United States, this development has become a trend. In Singapore, South Korea and other countries, toluene inks are being eliminated and will be replaced by alcohol-soluble gravure inks. It is foreseeable that inks for packaging in China will soon be the market for alcohol-soluble inks.
