Static Controls Take Charge

Built-in static generators

Package printing operations are plagued by static charge build-up from the very start. Static electricity is immediately generated as the web is pulled into the corona treater by idler, infeed nip and pacing rolls.

The print module itself produces numerous contact points, however, the wetting action of the ink tends to hold down any static build-up. As the web passes through tensioners in back-end operations, such as rewinding, slitting or die-cut and stacking operations, it begins to accumulate a static charge.
