The importance of plasma treatment equipment for pretreatment of film materials before printing:

I believe everyone is no stranger to thin film materials. Optical films, composite films, plastic films, metal films, superconducting films, etc. are all common thin film materials, and these thin film materials generally require pretreatment, plasma The surface treatment method of the treatment equipment is a relatively new pretreatment method. Through the treatment of the plasma treatment equipment, the surface of the film material can be cleaned, activated, and roughened, thereby improving the surface tension and adhesion of the film. Some friends I don’t know much about this. Let’s use examples of typical plastic films in the packaging and printing fields to illustrate the necessity of pretreatment of film materials.
The plastic film is light and transparent, resistant to oxygen and moisture, smooth and foldable. It has advantages in performance and price. Therefore, it can often achieve better results in modern packaging and printing. However, the plastic film is a non-polar polymer material and has poor wettability. , The ink is not easy to adhere, and the color fastness is poor; if the ink is directly bonded without pretreatment, it is easy to fall off, and the printing effect is poor, which affects its printing and packaging effect.
In addition, pre-treatment can also improve the processing quality of subsequent plastic film coating, lamination, and bronzing. Therefore, before printing, plasma processing equipment must be used to process thin film materials, or other pretreatment methods must be used. The differences between several commonly used pre-processing methods will be introduced in the following articles. Welcome everyone's attention. If you have any questions, please feel free to inquire.
