BOBST: A question of surface tension
A question of surface tension
BOBST is the leading supplier of equipment and services in the
folding-carton, corrugated board and flexible materials converting
In line with its policy of always offering high performance solutions
to its customers, BOBST has signed an exclusive deal with Plasmatreat
to represent their Openair® plasma systems in the area of packaging
folding and gluing.
Surface tension is the key to the bonding of synthetic laminated, varnish coated and fully plastic boxes.
With low surface tension, the resultant bond is poor because adhesion
occurs only at the points where glue droplets form. However, following
atmospheric plasma treatment and the consequent rise in surface tension
above 72mN/m, the adhesive will adhere to the entire surface and will
form a homogeneous high strength bond. It is to ensure this homogeneous
bond that plasma treatment is carried out in-line, immediately before
Thanks to this exclusive agreement with Plasmatreat, BOBST has made it
possible for its customers to benefit from the clear economic advantages
of reducing their glue investment when processing laminated boxes, and
of reducing print costs, by removing the need to create varnish cut-outs
on varnished boxes – all the while maintaining high production speeds.
Openair® Plasma Systems:
easy to install on the machine
delivered with the necessary fittings and interfaces for any BOBST or competitor folder-gluer
With these advantages, Openair® plasma treatment is, without doubt, a
system that will gain the attention of many converters who are searching
