100% reliable – Openair® plasma pretreatment for wet labeling on plastic bottles
labeling on plastic bottles is unthinkable without Openair® Plasma.
Plastic surface tension is so low that it makes wetting with
water-based adhesives impossible. The adhesive can’t achieve any
bond on these non-polar bottles. That’s the reason why plastic
containers are often labeled using expensive self-stick labels, or
hot melt or dispersion adhesives are used.
Wet labeling on plastic bottles
makes labeling as easy on plastic as on glass bottles. Plasma surface
technology significantly improves wettability of the surface to be
labeled. Especially where high-speed labeling is
involved, the simple inline integration of plasma jets can result in
