DDU wants to offer the right technology for your application
Plasma is a revolutionary surface treatment technology.
This breakthrough system successfully treats a wide range
of substrates for the optimal treatment and functionalizing
of web surfaces. Systems can be customized to fit most
production lines.

Corona treating increases the surface energy of plastic
films, foils and paper to improve wettability and adhesion
of inks, coatings and adhesives. Treating works best when
a substrate is treated at the time of extrusion and in-line
prior to converting. Corona treating increases quality
and productivity through improved print quality, faster
press speeds and less scrap.

A plasma field is formed when flammable gas and air are
combined and combusted to form an intense blue flame.
Brief exposure to the energized particles within the flame
affects the distribution and density of electrons on the
substrate's surface and polarizes surface molecules through
oxidation. This method also deposits other functional
chemical groups that further promote ink wetting and adhesion.
Flame-plasma treatment generates more heat than other
treatment methods, but creates greater surface energies
with a longer shelf life. Flame treatment is commonly
used to process injection and blow-molded products because
of the thickness, size, and shape of the parts.
