THE CHALLENGE
Surface Adhesion Failures Cost You Time and Money
Poor corona treatment leads to rejected product, wasted materials, and production shutdowns. We build treaters that solve these problems at the source.
01
Ink Adhesion Failures
Inks that won’t bond to film substrates cause print defects, customer complaints, and costly reprints. Low or inconsistent dyne levels are almost always the root cause.
→ Precision watt density control
02
Unplanned Downtime
Conventional corona treaters require frequent maintenance, carbon tracking cleanup, and electrode replacements — pulling your line offline when you need it running.
→ Carbon-track elimination
03
Inconsistent Treatment
Manual gap adjustments and aging electrodes create treatment variation across your web, leading to quality issues that compound downstream.
→ Automatic gap adjustment
