CONVERTING
CONVERTING SURFACE TREATMENT
Converters convert plastic films and other materials into a final product. Converting includes processes such as printing, laminating, and perforating films. A typical example is the production of tailor-made food packaging films.
Most plastic film producers subject their films to a plasma surface treatment immediately after production. However, as the treatment effect decreases over time, the surface energy of the film often becomes insufficient for optimal results by the time the film reaches the moment of conversion. In these instances, converters apply what is known as a refresher corona treatment to the material. This treatment not only enhances surface energy and increases wettability but also enables the converter to achieve the best possible results. Surface energy, therefore, becomes a variable that the converter can influence.
The converting industry faces major challenges due to increasing demands for flexibility and throughput in their production facilities, as well as constantly evolving material characteristics. Armed with the necessary software, hardware, and decades of experience, SOFTAL rises to meet these challenges. Entrusting us with corona and refresher treatments allows you to focus on your core business with peace of mind.
CHARACTERISTICS
Adhesion guaranteed
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.
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 costs, long life, and optimum operator safety are considered early in the development process to ensure maximum user-friendliness and uptime.
Customer-specific interfaces and solutions
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.
Material types
Some materials require an extremely high-powered plasma discharge to achieve the desired effect, while others are so sensitive to electric discharges that they would be destroyed even by a standard low-power plasma discharge. For every material, there’s a solution – just ask us.
Refresh treatment
Most plastic film producers subject their films to a plasma surface treatment immediately after production. However, as the treatment effect diminishes over time, the surface energy of the film often becomes inadequate for optimal results by the time the film reaches the conversion stage. To address this, converters administer a so-called refresher corona treatment to the material. This treatment enhances surface energy, increases wettability, and ensures that the converter attains the best possible outcomes.
The environmentally friendly alternative
Eine Plasma-Behandlung ist die bessere Alternative zur Anwendung nass-chemischer Primer. Die aufwändige Lagerung und Entsorgung von Chemikalien entfällt ebenso wie die energie- und zeitintensiven Prozessschritte zum Auftragen und Trocknen des Primers.
RESULTS
High wettability
Improved adhesion
