High-quality folded boxes are often difficult to glue, as they are often provided with a surface made of polyolefins or varnishes, which make gluing difficult or even impossible.
In order to be able to glue the boxes anyway, additional, expensive or aggressive special glue is used or the surface is removed mechanically with brushes or milling cutters.
Grinding and milling produce dust. The dust can contaminate the production environment and must be removed accordingly.
Plasma pretreatment is an elegant alternative to improve the adhesion.
Plasma pretreatment is a simple, inexpensive and controllable type of pretreatment.
The plasma activates the surface and thereby increases its wettability, so that the adhesive can spread well on the intended adhesive surface. Furthermore, the pretreatment creates an active surface, which enables the adhesive to have significantly higher adhesive forces.
Reduced environmental impact
Can be used on all folder gluer machines, installations have been made on Heidelberg Diana X and older, Heidelberg EasyGluer, Bobst Alpina, Bobst Domino, Duran Omega, Vega Polaris etc.
