plastic printing substrate Germany

... fed with extra oxygen. This causes the breaking of molecular bonds in the surface of the substrate to be treated, and the binding of active ions, mainly OH and COOH groups existing in the flame. In this manner, polar groups, enabling the secure bonding of printing inks, lacquers/paints, adhesives, etc. are created in the originally nonpolar material. Due to the formation of polar groups, the surface energy of the treated substrate increases to a measurable amount.
