Abstract
A corrugated pizza box is made using a web fed rotary die cutter with the web produced by a corrugator singlefacer that is speed synchronized with the rotary die cutter. The singlefacer produces SemiCorr Singleface Board (SSB) made possible by special corrugating rolls that allow a bottom liner to be bonded to a fluted and creased medium or liner within the singlefacer. This medium or liner has cross flute bond lines that provide in-line stiffness to the two-ply board exiting the singlefacer.
