Treated and untreated plastic films are indistinguishable to the naked eye. Usage of insufficiently treated films causes delays and waste, which can quickly became a major problem in an industry that demands highest levels in quality, performance and production output. This is especially true in the converting industry, so information needs to be available quickly and simply.
Das Auftragen und Auswerten einer Testtinte dauert nur wenige Sekunden.
To perform the test, a line of ink is applied to the film with the pen and the behaviour of the ink observed. If the ink forms a solid line, the film has a surface energy of at least 38 mN/m and can be used for printing and other converting steps. If the ink contracts and does not form a solid line, the film’s surface energy is below 38 mN/m. This indicates that the film is insufficiently treated for most converting processes.
Its ease of use, reliability and competitive price have made our product the no. 1 best selling corona test pen in the world!
