Laser Coding on Foil
Laser coding on foil is a trade in its own right. This is well understood by Packtronic and in order to ensure that we are able to always integrate the right solution, we have extensive test possibilities at Packtronic. These facilities allow us to test foils with different compositions and colours. Even at high speeds.
Several chocolate factories use the Linx SL301 30W laser. The ultra-fast galvos of this laser allow it to achieve 1200 bars of chocolate per minute. For this purpose, the Linx lasers are integrated in the flow wrappers, where the foil is being coded just before the moment the bars are wrapped.
At Perfetti van Melle, we code with a Linx SL301 laser on transparent foil, in which Mentos rolls are wrapped. The laser replaces an inkjet printer, whose ink didn't adhere sufficiently to the smooth foil. The Linx SL301 laser made it possible to obtain an indelible code and to significantly increase the efficiency of the line.
