Why is a plasma cleaning machine used before packaging printing and bonding? Is it effective after plasma cleaning?

In the process of painting, bonding, packaging and printing, the surface of the material must be cleaned once to better adhere to the surface. However, the reality is that many materials

 not only contain grease and dirt that can hinder moisture, but also their clean surfaces cannot be completely wetted by various liquids, adhesives, and paints. Even after curing and drying, 

they cannot adhere to the surface.

We investigate the reason because the surface energy at the bottom is lower. Materials with lower surface energy can warm materials with higher surface energy, 

but cannot be reversed. The surface energy of the added liquid, also known as surface tension, must be lower than the surface energy at the bottom in any case. In low-pressure plasma, in 

addition to air and oxygen, other gases can also be used, which must be able to adsorb various gas reactive groups such as nitrogen as oxygen sites.

Due to the adsorption of new dirt over time, the activity on the surface of plastics remains effective after a few weeks or months, but subsequent treatment should be carried out as soon as possible. Nowadays, silicone rubber materials such as PP/PTFE are being treated with linear wide width plasma cleaning machines, 

which can quickly improve surface adhesion and cohesion. In addition, metals, ceramics, and glass usually have higher surface energy than plastics, rather than just activation, but etching. 

However, in the process of using plasma cleaning activation treatment, a linear wide width plasma cleaning machine is used to activate the plasma, making the surface characteristics very

 ideal and widely applicable to process steps such as packaging printing, bonding, or coating. Low temperature plasma cleaning treatment can ensure a more cost-effective and

environmentally friendly production process, packaging, printing, and bonding of non-polar materials such as polypropylene, polyethylene, or recycled materials.

The activation pretreatment technology of plasma cleaning equipment is a very effective method for the application value of many manufacturing equipment processing technologies, and 

it is also a key technology with cost-effectiveness and environmental significance. Low temperature plasma cleaning of nano coatings also helps to provide good food packaging gases, 

such as outer packaging manufacturing: bottle caps, baby bottles, mineral water bottles, which are activated and modified by plasma cleaning. The plasma cleaning function activates 

plastics to high surface energy, usually reaching high levels; The activation effect of plasma cleaning machine has a long storage time, 

and the product's validity period can be extended to 12 months; The functional surface modification of plasma cleaning machine makes the use of new material combinations more 

effective, and plasma treatment can achieve the effect of single-sided treatment of plastic film.
