Corotec manufactures corona treating equipment for both conductive and non-conductive materials, with system-matched power supplies and power density controllers to assure reliable, economic performance under the most demanding production requirements. Our broad product line includes specially designed treaters for narrow webs, wide webs, three dimensional products, sheet-fed, blown film, and custom systems for controlled atmosphere treating and other technically advanced applications.


We constantly innovate and refine the technology for the corona treating process.

We at Corotec have earned our leadership position in this fast-moving industry by constantly innovating and refining the technology involved in the corona treating process.

In 1986 we introduced our first solid-state, high-frequency treater and the first power density control system. After years of reliable service in thousands of installations, these proven system innovations still lead the industry in performance and versatility. Today we offer 3 different power supply product lines with output ratings from 500 watts through 50 kilowatts, optimized for either low cost, compact size, or high performance for applications which demand a feature rich system.

Our latest system designs meet the ever-increasing need for higher and more consistent dyne levels on a wide variety of new laminates, metallized materials, and for those switching over to UV-curable or water-based inks and adhesives.
