It is understood that the current domestic plastic gravure printing ink is mainly based on solvent-based inks. Excessive benzene poses a great harm to the human body. Gravure printing at high speed requires the use of highly volatile inks to meet the printing requirements. This makes the environmental issues in the gravure printing process. Especially prominent. Due to the absence of volatile organic solvents, water-based inks completely eliminate toxic and harmful substances in solvent-based inks and avoid contamination of packaged goods. It is the only non-toxic ink approved by the US FDA in all types of inks. At present, there are only a few manufacturers in the country producing this type of ink, but due to the water-based ink in the gravure printing its adhesion, printing speed, gloss, etc. can not fully meet the solvent-based ink performance level, temporarily unable to meet the plastic film color packaging printing manufacturers Claim.
According to statistics, there are more than 10,000 packaging companies with an annual sales income of over 50 million yuan, of which nearly one-third are plastic packaging products companies. Of these companies, only a few companies had their own testing laboratories in the past, and now small businesses have begun to pay attention to establishing their own testing laboratories. Experts pointed out that because most plastic packaging products have the function of blocking water vapor, oxygen, and carbon dioxide, the demand for paper type packaging detectors will increase.
The packaging and printing industry project department recently introduced packaging inspection instruments to the market. Including oxygen permeability tester, water vapor transmission rate tester, carton compression machine, bursting strength tester, tension tester, ring pressure tester, carbon dioxide permeability tester, and package sealing test Systems, such as Headspace Analyzers, Bursting Testers, and German Brugger Heat Sealers, UK DIFFUSION Hazemeters, US IMI Peel Testers, and Friction Coefficients.
