Blame the Corona Treater
The Truth about Dyne Levels, Watt Density & Adhesion
When inks, coatings, adhesives and laminations don’t bond with substrates, converters are quick to blame the corona treater. And why shouldn’t they? Corona treaters are responsible for adhesion, right? Well, not exactly.
This article looks into the relationship between the corona treater and adhesion. We’ll dive into topics such as: what a corona treater really does, how to measure applied treatment (watt density), ways to measure effectiveness of treatment (dyne levels), effects of small changes in material and processes, and how all of these items play a role in providing you with successful adhesion.
