Aluminum plate Etching
Aluminum plate Etching is a technology that etches the electrolyzed aluminum on the face of the aluminum-coated laser holographic foil, such as PET,OPP,PVC or BOPP foil, with chemical agent. In this way, specific trade marks or any other patterns with the unique engraved effect and holographic bright will appear on the film surface.
The precisely positioned partial etching is a very complicated technology.
The technology was first used in making the security mark on the banknote of Euro and works very well. |
