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.
Claims7
A pizza box fabricated from a two-ply panel with the two-ply panel made from a corrugated product comprised of:
- a bottom liner;
- and
- an inverted creased base layer of medium or liner that has a first flute type having opposed tips directed in a downward direction and upward direction, respectively, to define a fluted web and multiple cross flute bond lines creased to produce orthogonal edges at intervals across the fluted web with the multiple cross flute bond lines facing in an upward direction;
- wherein the bottom liner is bonded directly to the fluted web and the multiple cross flute bond lines of the creased base layer of medium or liner to provide exposed flute tips and orthogonal creases on an inside of the pizza box and the bottom liner defining an outer surface of the pizza box.
