Corona Station

The task

Plasma technology first became commercially available in the 1950s. As more and more possible applications for plasma were discovered, the technical challenges rose. New processes were found, new solutions became market ready and laboratory trials became patented products.

As an early pioneer in the plasma market, SOFTAL has always been part of the corona world. In over 50 years, SOFTAL has constantly pushed the boundary of technical possibilities. Today, corona and plasma solutions by SOFTAL are in use worldwide. We have produced over 10.000 corona stations and more than 250 corona systems for film stretching lines.

From the outset, the focus has been on the market and the demands of our customers. Our systems are fine-tuned to match the material to be treated and the available budget.

Typical for SOFTAL products are the many small and large details that ensure uninterrupted operation and maximum up-time in everyday production life. This might simply be a choice of ideal components, or more complicated design details, like a removable electrode module for easy maintenance. Decades of experience and progress contribute to every single design step in all or our products.

Adhesion guaranteed

We are proud of our growing global customer base that includes manufacturers of film production lines, finishers, film producers and research companies.
Naturally, the portfolio of products offered by SOFTAL is just as multi-faceted as our customer base. This is made possible by the modular design of our treatment systems, which allows customer-specific changes and a rapid development of new systems and processes. This ideal starting point allows us to meet customer demands and achieve results. Guaranteed.

Install and forget

SOFTAL has been part of the corona and plasma industry for more than half a century. Our engineers and developers know, what really matters at the end of the production day. Factors like easy maintenance and service, low operating cost, long life and the optimum in operator safety are considered early in the development process to ensure maximum user-friendliness and up-time.

Customer-specific interfaces and solutions

The numerous hardware and software solutions offered by our treatment systems ensure seamless integration into customer-specific systems and processes. Starting from proven standard components, our systems can be modified to suit any material and/or process. We specialize in the surface treatment of your materials – so you can concentrate on your core business.


Shape, material and position of the corona electrode assembly, along with the characteristics of the related treater roll, determine the homogeneity and efficiency of the plasma discharge. Constant further development of our electrodes has generated a number of patents, including our Intelliblade™ electrode and our liquid cooled ceramic electrodes, both of which have been tried and tested hundreds of times.number of patents, including our Intelliblade™ electrode and our liquid cooled ceramic electrodes, both of which have been tried and tested hundreds of times.

Material types

There are film materials that require an extremely high-powered plasma discharge to achieve the desired effect, others are so sensitive to electric discharges that they would be destroyed, even in a standard low-power plasma discharge. There is a solution for every film – just ask us.

Reliable service

The name SOFTAL is synonymous with premium quality systems and a high level of customer satisfaction all over the world. Our unique network of comprehensively trained service professionals located in strategically chosen countries allows us to be personally present in international locations in a matter of hours.
