It is understood that the current domestic plastic intaglio ink to solvent-based ink, excessive benzene harmful to human health, and high-speed gravure printing, you must use the volatile ink in order to meet the printing requirements, making environmental issues in the gravure printing process is particularly prominent. Because water-based ink does not contain volatile organic solvents, completely eliminating solvent-based inks in the toxic and harmful substances, to avoid pollution of packaged goods, is the only variety of ink through the U.S. FDA approved non-toxic ink. Currently only a very few manufacturers to produce the varieties of ink, but because of its water-based ink adhesion in gravure printing speed, gloss, etc. can not fully meet the performance levels of solvent-based inks, sometimes unable to meet the plastic film color printing packaging manufacturer requirements.
User requirements at the national and packaging products manufactured in strict accordance with the standard case of an increasing demand for raw materials and packaging products, testing instruments market beginning to heat, a variety of domestic and imported packaging testing instruments have appeared in special market.

According to statistics, China's annual sales revenue of 5.00 million yuan more than 10,000 packaging enterprises, of which nearly one-third of plastic packaging products business. These enterprises in the past only a few enterprises have their own testing laboratory, and now small businesses have begun to attach importance to establish their own testing room. Experts pointed out that the barrier plastic packaging products, most with water vapor, oxygen, carbon dioxide functions, so the instrumentation of this growing demand.
