Corona Treating: What is Overtreatment and Plasma Etching?

what is plasma etching and overtreatment in the corona discharge corona treating process

Overtreatment can be costly to your company and product. It is easily avoided following the proper formulation for power requirements per your adhesion process and material characteristics. When the material is treated at higher power levels than necessary, we can expect overtreatment. The material’s structure will only allow a certain increase in surface energy depending […]

Corona Treater Maintenance

sheet format corona treater for improving adhesion quality and print quality

As with any industrial equipment, a good maintenance schedule helps extend the lifespan of the treater and lower the rate of expensive service costs. A good maintenance schedule includes: Cleaning and lubricating treater rolls. Remove material deposits with a good industrial cleaner. Remove deposits from electrode insulators regularly to prevent buildup of conductive material. Clean […]

The Truth about Dyne Pens

the truth about dyne pens

Attending industry trade shows has given me a lot of insight into the printing industry and the lack of knowledge in achieving a guaranteed bond. My experience in manufacturing has shown that small errors can lead to excruciating losses. The misunderstanding and mismeasurement of characteristics required for a guaranteed bond is one of those dangerous […]

Basics of Web Corona Treaters

bare roll corona treater for converting

Surface treatment definition: “The modification of the surface to increase surface tensions resulting in better bonds of ink, glues and laminates.” Corona treatment is a web surface preparation process that applies corona discharge to a substrate to raise the surface energy to a compatible level with inks, glues, and lacquers to allow a better bond. […]
