Difference of Corona Charging and Tribo Charging
| Critical Variables | Corona | Tribo |
| Faraday Cage | More difficult to coat recesses | Easier to apply to recesses |
| Back Ionization | Easier to coat thinner films | Easier to produce thicker films |
| Products configuration | Not good for complex shapes | Very good for complex shapes |
| Production requirements | Wide range of line speeds | Good for lower line speeds |
| Powder Chemistry | Less dependent on chemistry | More dependent on chemistry |
