Success Story with Tampoprint
Altogether we can state that the application of the Openair-Plasma® method in pad-printing automation can be judged positive on all sides.
Secure ink adhesion and a clean print image on PP packages of mints thanks to inline plasma activationBedrucken von Mintcards.
Tampoprint AG was tasked to develop and construct a pad-printing full-automatic for 5-colour printing (raster image printing) on “mint boxes” with an hourly production rate of 1800 parts.
In cooperation with our customer, a catalogue of requirements was made which, among others, contained the following points:
- material PP
- wetting of the surface of at least 72 mN/m (water wetting)
- complete removal of the outwards diffusing mint oil
- complete removal of dust particles on the surface
- no damage of the work-piece’s surface
- no damage of the contents (peppermint dragees)
- integration feasibility into a full automatic
Very soon, it became obvious with these demands that no conventional physical pre-treatment method (gas or corona) could come to use here. After we had become aware through technical publications and our customer of Plasmatreat’s Openair-Plasma® method, everything went very fast, thanks to their professional support.
With the defined requirements, different test series were conducted and finally all criteria met. The installation has been working three shifts a day for years and to our customer’s greatest satisfaction. This example is not an isolated case. Altogether we can state that the application of the Openair-Plasma® method in pad-printing automation can be judged positive on all sides.
