Measurement of surface tension

The new 38 dyn/cm quick test pen is used to quickly and easily measure the surface tension of PE or PP films to indicate their printability with solvent based inks.

Is the surface energy value of a treated film 38 dyn/cm or higher, the ink will remain as a solid line. If the value is below that, the ink bubbles.

Thanks to the solvent based ink contained in the pen, the applied line dries in just a few seconds and makes wiping unnecessary.


  • Quick and easy proof of surface treatment
  • Exceptionally easy to handle
  • Fast-drying ink
  • Excellent readability due to particularly strong color
  • Minimal consumption of test ink
