Using a long focal length beam delivery setup, several single-face corrugated paper samples were cut at a designated line speed of 360 inches per minute. Single-face corrugated paper consists of corrugated (fluted) medium bonded to a flat linerboard facing. Corrugated sheeting is used primarily by shippers as a packing or padding material.

In both tests shown here, beam delivery through a 7.5” focusing lens, 0.012” spot diameter and 0.54” depth of focus, coupled with five PSI of nitrogen gas assist produced clean cuts that exhibit minimal charring.

A 21-pound corrugated sample (0.375” high flutes on 3/4" inch centers) was cut using 109W at a speed of 360 IPM.

The black 33-pound stock, with 0.5” high flutes on one-inch centers, was cut using 142W of laser power.
