Plasma cleaning machine can increase active groups and improve surface hydrophilicity before packaging printing

Before the adhesive treatment of packaging materials such as plastic film and plastic containers, many manufacturers often leave behind impurities such as oil stains and release agents. How to make the surface rougher and more polar has been a long-standing problem. How to use plasma cleaning machines to improve the adhesion of packaging printing ink, make the printed patterns clearer, more firm, and less prone to fading and falling off, is a top priority for current and future considerations.

For example, in the production of plastic food packaging bags, it is often encountered that the printed text and patterns are not bright and complete enough, and the handwriting is prone to blurring and fading. Based on this problem, the emergence of plasma cleaning machines can help solve this problem. Plasma cleaning technology can clean surface impurities while also

 activating modified spraying. After plasma cleaning treatment, even after long-term storage and transportation, there will be no blurring or fading. Online plasma cleaning equipment can also improve product efficiency, reduce production costs, and be energy-saving and environmentally friendly.

The rotary nozzle of the atmospheric pressure plasma surface treatment machine of Zhenyi Co., Ltd. can process panels with a total width of more than 3 meters at a rate of 25 meters/min. In the pre-processing stage of packaging and printing, the plasma surface cleaning machine is one of the indispensable processes in packaging production. 

For example, for paper box packaging, the plasma cleaning machine can improve the wettability of the cardboard surface, allowing water-based ink to better penetrate and adhere to the surface, improve printing quality, reduce ink usage, and lower costs. In addition, the plasma cleaning machine can enhance the strength of the paper box surface and improve the durability of the packaging. 

For example, in the printing of high-end cosmetics paper box packaging, low-temperature plasma cleaning treatment can make the printing effect more exquisite and enhance the overall grade of the product.

Common QR codes and other labels usually require plasma treatment on the surface before printing to ensure good adhesion between the ink and the label material. Atmospheric pressure plasma cleaning machines can effectively remove residual pollutants on the surface, improve surface performance, and enable the ink to quickly dry and firmly adhere to the surface after printing, avoiding ink smudging or peeling again, thereby improving the printing quality and readability of the label. 

For example, electronic tags used in the logistics industry can maintain good printing quality and signal transmission capability after plasma cleaning treatment for long-term outdoor use.

Normally, traditional printing pre-treatment processes often require multiple cleaning and spraying processes, which are not only time-consuming and labor-intensive, but may also introduce new sources of pollution. With the help of low-temperature plasma cleaning machines, the dual effects of cleaning and surface activation can be achieved in one step. 

This simplified process not only saves time and labor costs, but also reduces quality risks caused by multiple processes. I believe that the role of plasma cleaning technology will be more widely applied in the future!
