The market of special testing instruments for packaging begins to pick up
According to statistics, there are more than 10,000 packaging companies with annual sales revenue of more than 5 million yuan in my country, nearly one third of which are plastic packaging products companies. Only a few of these companies used to have their own testing laboratories, but now small companies are beginning to face the establishment of their own testing laboratories. Experts pointed out that because most of the plastic packaging products have the function of blocking water vapor, oxygen and carbon dioxide, the demand for testing instruments in this regard will increase.
The project department of the packaging and printing industry launched a special testing instrument for packaging to the market not long ago. Including oxygen transmission rate tester, water vapor transmission rate tester, carton compression machine, burst strength tester, tensile tester, ring crimp pressure tester, carbon dioxide transmission rate tester, packaging sealing test Systems, such as headspace analyzer, rupture tester, German Brugger heat sealer, British DIFFUSION haze meter, American IMI peel tester and friction coefficient meter, etc.
It is understood that at present, domestic plastic gravure inks are mainly solvent-based inks. Excessive benzene is extremely harmful to the human body. However, the gravure printing speed is high, and it is necessary to use highly volatile inks to meet the printing requirements. This makes environmental protection issues in the gravure printing process. Especially prominent. Because water-based ink does not contain volatile organic solvents, it completely eliminates toxic and harmful substances in solvent-based inks and avoids pollution to packaged goods. It is the only non-toxic ink approved by the US FDA among various inks at present. At present, only a small number of domestic manufacturers produce this type of ink, but because the adhesion, printing speed and gloss of water-based ink in gravure printing cannot fully reach the performance level of solvent-based ink, it is temporarily unable to meet the needs of plastic film color packaging and printing manufacturers. Require.
