Plasma processing machine for plastic film to provide you with pretreatment solutions:
Believe that you are no stranger to thin film materials, optical film, composite film, plastic film, metal film, superconductor film and so on, are more common membrane materials, and the thin film material is typically preprocessing, surface treatment of low temperature plasma processor, is a new kind of pretreatment method, through the processing of plasma processor, can be carried out on the thin film material surface cleaning, activation and coarsening, thus improve the film surface tension and adhesion, some friends to pretreatment the link still don't know, let's through plastic film packaging and printing industry is a typical example, To understand the necessity of film material pretreatment.

The plastic film is light and transparent, oxygen-resistant and moisture-proof, smooth and folding resistant. It has advantages in performance and price, so it can often achieve good results in modern packaging and printing. But the plastic film is a non-polar polymer material with poor wetting, ink adhesion and color fastness. If the ink is directly bonded without pretreatment, it is easy to fall off and the printing effect is poor, which affects the printing and packaging effect.


In addition, the pre-treatment can also improve the subsequent plastic film coating, composite, bronzing and other processing quality. Therefore, before printing, the thin film material must be treated by plasma processor or other pretreatment methods.


Now that we have a certain understanding of the pretreatment of film materials, then the more common pretreatment of plastic film is chemical oxidation treatment, corona treatment and plasma cleaning treatment. The following to introduce the pretreatment of plastic film plasma processing machine processing.


Plasma processor device surface treatment method is in the process of ionization, forming active particles in plasma, react with plastic film material surface, thus destroy the long chain molecules on the surface of the membrane material, form the high-energy group, in addition, the thin film material after being bombarded with particle physics, will form the rough surface, make the surface of the plastic film material freedom can be improved, as to enhance the surface dyne value performance.


Plasma processing machine low temperature plasma surface treatment process is simple, easy to operate, clean and pollution-free, in line with environmental protection requirements, and safe and efficient treatment, no damage to the film material, suitable for mass production, production environment requirements are not high.
