For the last few years, the rate of counterfeiting has been increasing in almost all areas. Apart from financial losses in the billions, counterfeited medications can be fatal. For this reason, the Laser Zentrum Hannover e.V. (LZH) is working on a flexible marking and identification process which, among other things, can be used to make medications in glass ampules counterfeit-proof.

Using a robust and industrially established marking laser, it will be possible to both individually and quicklymark products with a distinct certificate of authenticity. This can be done during the packaging process. This is the vision of the project GLaSIDeE. Scientists at the LZH are working on a process for anti-counterfeit marking on both flat and curved glass surfaces.

The laser marking process can be used to generate decorative writing, a number, or a two-dimensional bar code directly in the glass. The markings are only a few nanometers deep. Flexibility is the main advantage, since each part can be individually marked, for example with a serial number, without effort or extra costs.

Up to now, there has been no clear identification process for markings on glass. Thus, in this project a special process should be developed with which each part is given its own individual fingerprint. The LZH is also developing a reading process for invisible markings. In combination with each other, they will be able to reach a higher anti-counterfeit rate than conventional processes.

In addition, laser marking machines also play a role in food safety. The use of lasers to mark the production date and barcode on packaging bags, packaging boxes, and packaging bottles can effectively track product information and prevent food safety problems caused by eating unqualified or expired food.

As an enterprise with more than ten years of industry experience, MACTRON has a variety of functional models of laser cutting machines and laser marking machines, which can provide you with high-quality laser equipment solutions.
