Increased demand for testing instruments in the packaging industry in China

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 testing instruments in this area will increase.

The packaging and printing industry project department recently introduced to the market the packaging-specific testing instruments produced by the US-based MOCON company. These include oxygen transmission rate testers, water vapor transmission rate testers, carbon dioxide transmission rate testers, and package sealing test systems, such as headspace analyzers, rupture testers, and the German Brugger heat sealer, UK DIFFUSION. Haze meter, American IMI peel tester and friction coefficient meter.

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.
