Treaters are often used before lamination to improve adhesion and before coating to improve wettability and adhesion.  (See the PDF of the Article below to see Figure 1.)

The functions of the four key components of a corona treater (See the PDF of the Article below to see Table 1 for more details.)

  1. High Voltage Electrodes
  2. Power Supply
  3. Treater Roller
  4. Ozone Exhaust

The best practice is to install powered static bar SBCT in Figure 1 on the web exiting the corona treater facing the treated surface. Corona treaters can deposit large amounts of static on treated surfaces.  This static is an unwanted by-product of treatment.  Dissipate static on the web from corona treaters using a powered static bar installed on a web exiting the corona treater facing the treated surface.
