BOBST: A question of surface tension
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.
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 gluing.
Openair® Plasma Systems:
- easy to install on the machine
- environmentally friendly
- delivered with the necessary fittings and interfaces for any BOBST or competitor folder-gluer
