Perforating

Roll materials such as cigarette-tip paper or packaging foil for the food industry are perforated using special, high-frequency excited, fast modulating CO2 lasers with extraordinary power stability. The perforation of cigarette-tip paper is used worldwide to reduce the tar and nicotine content of light cigarettes. Here, laser perforation ensures above all the adherence to the applicable threshold values in modern cigarettes. The perforation of foils for the food industry is used mainly to prolong the freshness and quality of perishable goods. When the holes are small enough, transpiration of moisture is prevented and at the same time an exchange of air is ensured.

With the PerfoLas system, the hole diameter can be set at 40 - 400 µm - and the perforation speed is now as high as 500,000 holes per second. Optional extras such as double-spot lenses, lenses for round and oval holes, zero-meter module and cutting equipment form the leading edge of technological development at the present time.
