Corona is still the most used and cost-efficient solution for increasing surface adhesion and promoting wetting. It is used on more than 95% of all the material converted in the packaging industry today, making Corona the right solution.
Corona is a Dielectric Barrier Discharge (DBD) in air, the electric discharge is controlled by a dielectric barrier, which is in the form of streamers distributed over the surface.
The objective of polymer treatment is to increase the surface energy and therefore the wettability and adhesion for laminating, printing, and other converting processes.
The last 5% of applications have special needs. Even today, some of these are impossible to meet or are solved in an expensive way that often involves one or more harmful components. These can contaminate the production area for the operators and are also harmful to the environment.
However, there is a more advanced technology available -iPlasma®. Created in a controlled atmosphere, adding small quantities of dopant gas for grafting and dopant it offers different functionality and a whole range of surface abilities.
iPlasma® is more homogeneous and ‘softer’ than Corona. It has lower heat impact on the surface, which enables versatile controlled and tuneable surface chemistry to be achieved. As a result, it can be considered as a gas primer that efficiently replaces both the use of Corona treatment and liquid primer.
Since the introduction of our industrial Atmospheric Plasma Systems in 2010, Vetaphone has supplied more than 50 units, and with the introduction of the new generation, named iPlasma®, we will pass 60 installed systems by the end of 2017.
Vetaphone supplies a complete solution that can be integrated with any type of roll to roll machine. The direct benefits of this ‘all-in-one’ eco-efficient plasma process are: reduction of costs; lower energy consumption; and a reduced impact on the environment.
Vetaphone offers state of the art plasma technology at atmospheric pressure for the benefit of customers. The direct benefits of this “all-in-one” eco-efficient plasma process are reduction of costs, energy consumption and impact on the environment.
