Lasers, especially high-frequency excited, fast modulating CO2 lasers with extraordinary power stability, are especially suited for perforating paper or plastic foils. Usually, web material is processed at winder systems at high speeds of up to 700 m/min. With laser perforating hole diameters ranging from 50 - 400 microns can be achieved. High sophisticated systems like the ROFIN PerfoLas provide perforating speeds of up to 420,000 holes per second.

Non-wear Perforation for Films and Paper

ROFIN laser perforation systems process web material, commonly films and paper, at a perforation rate of 500,000 holes per second using special optical beam multiplexer or fast galvo head systems. Depending on the web speed and perforation performance and flexibility required, ROFIN offers various highly sophisticated solutions.
