Corrugated board is the unsung hero of global commerce. Beneath its humble exterior lies an intricate structural engineering feat that balances fluting frequency, crush resistance, and printability.
The Anatomy of Flute Profiles
E-flute (approx. 1.6mm) delivers 90 flutes per foot, creating a remarkably smooth surface ideal for direct flexographic or litho-laminated printing. B-flute (approx. 3.2mm) provides superior puncture and compression resistance.
