With extremely compact dimensions and the consequent specific demands on corona stations and generators, surface treatment systems for label applications hold a unique position in SOFTAL’s product portfolio. While corona stations for film stretching lines can easily span widths of over 10 m, treatment stations for label applications sit at the opposite end of the spectrum, limited to just a few centimeters in width.

In label applications, corona treatment is employed to functionalize the surface of the material web, enhancing the adhesion of print colors, lacquers, adhesives, and other coatings on labels. The market’s need for relatively small systems demands compact corona stations that seamlessly integrate into new or existing production systems.

SOFTAL’s CLN series of corona stations and corresponding generators come equipped with multiple interfaces and tried-and-tested measurement, notification, and monitoring functions, making them ideally suited for integration into various systems. Their compact dimensions, lightweight nature, and cantilever design contribute to easily accessible systems. Furthermore, the CLN series of corona stations features a removable electrode module, further simplifying cleaning, maintenance, and process-specific applications.


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.

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.

When a film finally reaches the production facility of the converter, the surface energy of the film often falls short of delivering perfect converting results. In such instances, converters administer a so-called refresher corona treatment to the material to enhance its surface energy, augment its wettability, and ensure better adhesion of colors and coatings.

SOFTAL generators are setting the industry benchmark for efficiency and cost-effectiveness. Careful balancing among the generator, transformer, and treatment station ensures that the system operates at its resonance frequency. This ensures that the treatment system functions at maximum efficiency, maintaining the lowest possible operating costs throughout its entire lifespan.
