Mller Dairy chose a new laser-based coding and marking technology to replace traditional methods of coding and achieve higher productivity rates on its high-speed filling lines. DataLase, from UK-based Sherwood Technology Ltd., is a non-toxic ink, coating or substrate additive. When exposed to low power CO2 laser emissions at high speed, it provides a completely customized solution for image generation. DataLase is compatible with most resin materials and conversion processes, as well as common printing and coating techniques.

Sherwood worked with Alcan Packaging to apply a discrete patch of DataLase color change ink in the coding field of packaging materials during the printing stage. A number of state-of-the-art Domino CO2 scribing lasers were installed on the production line in order to write the date code onto the patch. The DataLase patch changes color from neutral to black where exposed to the laser beam, thereby producing a permanent mark. The coding process utilizes very low power at high speed.

Hayward Green, supply chain director, Mller Dairy, comments: “DataLase has allowed us to improve the quality and speed of our product coding and has also provided a more reliable process with far less down time on our very high capacity filling lines.”
