The surface tension of the plastic film can be accurately tested whether the values in the test pen, so that the user to clearly understand this The film is suitable for printing composite or aluminum vacuum, and effective quality control and reduce substandard material caused The waste or the duration of the delay.

Dyne test pen (38mN / m) can be used as a corona treated surface energy of a quick test tools, but not suitable for testing the system as has been printed or coated with a good surface.When the test pen to draw a line on the corona treated surface, and if it is continuously into the line, indicating that the surface of the material can not be less than 38mN / m, such as intermittent not connected into a line, and the material surface energy less than 38mN /m processing insufficient or even untreated, the printing process does not meet the requirements.The surface tension of the surface the wet force for accurate determination of printing inks and other materials in the surface bonding situation is very clear standards, but the impact of viscosity there are other factors, such as static electricity and many additives.
Notes: 1. Tightly the pen cover after finishing using. 2. Save in the cool place, avoid direct sunlight.
