Since the 1950s, when plasma treatment first became commercially available in the industry, it has evolved into an indispensable part of producing and converting plastic films and similar materials. Alternative processes often result in higher costs and effort, positioning corona technology as the most logical choice in many areas. In fact, existing processes can often be simplified using a corona system. After all, plasma is pure energy.

In a conventional corona treatment method, the plasma forms in the air gap between the corona electrode and the counter electrode. This plasma interacts with the surface of the material to be treated, initiating various chemical reactions and altering the surface properties.


We are proud of our growing global customer base, which 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, allowing for customer-specific changes and the rapid development of new systems and processes. This ideal starting point enables us to meet customer demands and achieve results. Guaranteed.

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 costs, long life, and optimum operator safety are considered early in the development process to ensure maximum user-friendliness and uptime.

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

The name SOFTAL is synonymous with premium-quality systems and a high level of customer satisfaction worldwide. Our unique network of comprehensively trained service professionals, situated in strategically chosen countries, allows us to be personally present in international locations within hours.

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

Shape, material, and position of the corona electrode assembly, combined with the characteristics of the related treater roll, determine the homogeneity and efficiency of the plasma discharge. Ongoing development of our electrodes has led to several patents, including our Intelliblade™ electrode and our liquid-cooled ceramic electrodes, both of which have been tried and tested hundreds of times.
