TECHNO CNC presents the Dyne Test Pen for Corona Treatment Check, a reliable and easy-to-use tool designed to measure the surface energy level of plastic films and packaging materials after corona treatment.
Surface treatment processes such as corona, plasma, or flame treatment are commonly used in industries to increase the surface energy of materials like BOPP, PET, PE, and PP films, allowing inks, adhesives, and coatings to adhere properly. The dyne test pen helps verify whether the treatment level is sufficient for printing, lamination, or coating processes.
The pen contains a specially formulated dyne testing fluid that spreads across the material surface if the surface energy level is equal to or higher than the value of the pen. If the fluid contracts or forms droplets, the surface energy is lower than the tested value.
This quick and practical method allows operators and quality control teams to instantly evaluate corona treatment effectiveness on plastic films and packaging materials.
Dyne test pens are widely used in printing presses, packaging plants, BOPP tape manufacturing units, film converting industries, lamination lines, and plastic processing facilities, where proper surface energy is critical for achieving strong ink adhesion and coating performance.
