Openair® plasma systems for the activation of plastic films with long-term stability
To
be able to print
and coat
plastic films, the surface
tension
of the material must first be increased. In addition, coating
requires long-term stability of surface
activation.
In the methods previously available, such as corona
treatment
or flame treatment, surface tension decreases after a short time.
Pretreatment
with the Openair® process results
in reliable surface activation of the plastic films – activation
that displays outstanding long-term stability. Inks
and coatings
are optimally absorbed.
Openair®
film systems use special wide-opening
nozzles. They make possible reliable treatment with
atmospheric-pressure plasma in any width. An additional positive side
effect of the pretreatment of the plastic with Openair® plasma is a
noticeable anti-static effect.
Activation of films on winders
Openair® plasma systems for the pretreatment of plastic films – advantages and properties:
- Pretreatment with long-term stability due to high surface activation
- Possibility of partial activation
- Additional cleaning effect of additives
- Anti-static effect
- Treatment width per nozzle = 25 mm
- Single-sided pretreatment
- High processing speeds
