Performance:
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.

Test Method:
In industrial practice, the plastic surface energy (surface tension) was measured by the test ink in accordance with DIN ISO 8296,Is based on a of known different surface energy ink brush on the film to be measured approximately 100mm long ink sticks,And observe more than 90%.Ink edges within 2 seconds shrinkage and the formation of the ink droplets, if any, for the low-level surface energy of ink painted ink sticks into.The line is the same observation, until no contraction and the ink droplets,this test surface of the ink can be that corresponding to the surface of the film can.This method can accurately measure the surface tension of the substrate, the wet surface force, and determines whether the substrate surface before work factors meet the requirements in order to adjust the ink, coating viscosity to the desired.30 to 72 mN / m, 21 kinds of the surface level of the test inks (each difference 2mN / m).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.These factors, however, shows that in the test but not often, and even test results good but actually undesirable. This needs to be discussed and raw material suppliers of these technical issues.In general, the above situation does not occur to them, and the surface value in the 38-41mN / m that is able to achieve the viscosity requirements. Below 37mN / m surface tension will cause many of the white pages (no printed content), good viscosity below 35mN / m.
