Surface treatment utilizing corona technology

The task

Since the 1950s, when it first became commercially available in the industry, plasma treatment has developed into an indispensable part of producing and converting plastic films and similar materials. Alternative processes often lead to higher cost and effort, which makes corona technology the only sensible choice in many areas. In fact, existing processes can often be simplified with a corona system. After all, plasma is pure energy.

In a conventional corona treatment approach, the plasma forms in the air gap between the corona electrode and the counter electrode. The plasma reacts with the surface of the material to be treated, causing different chemical reactions and changing the surface properties.

SOFTAL was founded over 50 years ago and became an early pioneer of corona technology. In our long history as a market and technology leader, we have used many opportunities to improve on designs utilizing corona and plasma technology and to usher this technology’s tremendous success in the market. Our product portfolio was constantly refined and increased to, always one step ahead of our customers’ demands.

In several project partnerships with universities and corporate development departments, our R&D department is constantly investigating new approaches to the application of plasma treatment. This has been the origin of a number of solutions that became SOFTAL patents and are now commercially available as 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.

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.

The environmentally friendly alternative

Plasma treatment is the better alternative to wet chemical primers! The high costs for storage and disposal of chemicals are eliminated as well as the high energy and time consumption of the process steps for primer application and drying.

Corona stations

The portfolio of products offered by SOFTAL is as diverse as the possible applications of corona technology. Our corona and plasma systems are always based on our tried and tested standard components, but specifically chosen and adopted to meet the demands of your materials and processes.

Corona generators

SOFTAL corona generators are, of course, just as adaptive as our corona stations. It goes without saying that the products of a company that has been successful in the market for decades offer the ease-of-use, robustness, low maintenance and service costs and numerous small and large solutions for smooth everyday production work that you expect form a global player.
