In the production process, certain plastics, such as polyalkylene by plastic is the need for surface treatment. Be processed after the plastic is not only to increase its hardness and also improve its life, surface finish, flatness and aesthetics, the so-called fully staffed So much. From the category, the plastic surface has chemical and physical methods; then in turn contains a chemical oxidation method, a chemical treatment method, solvent treatment method and the like in the chemical methods, physical treatment methods include corona treatment, flame treatment method, etc. .
Many branches, take one of the various methods and film material handling methods used in three ways:
A corona treatment method. By a high pressure charge is discharged to the surface of the film, in the role of ionizing, the film surface is roughened and increased surface energy, increasing the ability to bind with the ink, to achieve the purpose of strengthening ink layer fastness.
Second, the surface is coated. In the production of self-adhesive material, the surface of the film before or in the process of production of adhesive materials coated with a special coating, the purpose is to improve the surface tension of the film, to enhance the binding capacity of the film with the ink.
Third, the printing process. The transformation of the film surface characteristics in the film production process using a special process by chemical methods, in order to increase the binding force of the ink on the film surface by a plastic film manufacturer.
So, the plastic surface treatment process is quite complex, and not professional documents, half past one will have to learn is also more difficult.
