The principle is to use high-frequency and high-voltage corona discharge (high-frequency AC voltage as high as 5000-15000V/m2) on the surface of the plastic to be treated to generate low-temperature plasma (plasma surface treatment) cause a radical reaction on the plastic surface. The polymer is crosslinked. The surface becomes rough and increases its wettability to polar solvents-these ionic bodies break their molecular structure by electric shock and penetration into the surface of the printed body (plasma surface treatment) and then oxidize and polarize the surface molecules being treated; Ion electric shock erodes the surface, which increases the adhesion ability of the substrate surface.

A plasma processor is used for online processing and can be used to process curved surfaces when equipped with various production lines. (Plasma surface treatment) There is no limitation on the size of the object. The two effects are the same, but the one is more suitable for the processed object.
