📚Plastics Innovation and Technology🎓🎓

The oxygen in the air serves as the raw material for this oxidation. This reaction is initiated by high-energy electrons in the discharge gap, which cause bond dissociations on the plastic surface.As a result of the oxidation reactions, polar groups containing oxygen are implemented in the surface, resulting in improved wettability of the surfaces and in most cases also improved bonding on the plastic surface. As the corona dosage increases, so too does the number of polar groups and thus the wettability. One measure of wettability is the surface tension, which on smooth surfaces such as foils can be reliably and easily determined with test inks.
