This diagram shows a section of the blank of the TimeSaver Box. It depicts how this box gets its material savings (or, conversely, how the traditional pizza box creates its waste).

SUMMARY: The TimeSaver Box (a.k.a. new green pizza box) derives its 7% to 8% material savings by eliminating the roll-over flap (or inner panel) on the front wall of the traditional pizza box. The only function of this panel is to set up the two front corners of the box. The panel serves no other purpose and provides no other significant benefit.
The unique InstaFold Corner Locks of the TimeSaver Box make this roll-over flap unneeded. As a result, the TimeSaver Box enables (a) ultra-fast box-folding, (b) a substantial material savings, and (c) an impressive cost savings (resulting from the material savings). And, it does all this with no reduction in functionality or pizza-carrying performance.
