Design Guide: Choosing Between Flute and Cell
When evaluating protective board materials, the question is rarely “Which board is stronger?” Strength is not an absolute property—it is conditional, directional, and dependent on how a material is loaded. A more precise design question is: “What behaviour is required for this application?” Both fluted and cellular (honeycomb) corrugated systems…

(3) Adherence in Corrugated Performance
Corrugated cardboard is frequently defined by its geometry: flutes, cells, and voids. Yet geometry alone does not dictate performance. A corrugated structure is only as ‘intelligent’ as the surfaces that restrain it and the bonds that unify it. Liners and adhesives are not passive layers; they are the active mechanisms…

(2) Cellular Structures in Corrugated Performance
At first glance, honeycomb board appears over-engineered for paper-based packaging. Its rigid panels resist folding, its calliper feels excessive, and its cellular interior seems better suited to aerospace than logistics. Yet this perception misunderstands the mechanical intent of cellular structures. Honeycomb is not designed for efficiency through linear order; it…

(1) Fluting in Corrugated Performance
Beyond its appearance as a simple commodity, the corrugated container represents a highly optimised, low-impact feat of structural engineering: the flute. By suspending a continuous paper wave between flat liners, engineers achieve the load-bearing efficiency of I-beams and Roman arches using minimal material. Strength is generated through geometry rather than…

Rethinking the Fold through Elastic Hinge Strategies
Instinctively, we tend to assume that a corrugated container becomes more durable by being solid, that stiffness creates strength, and structural integrity is measured by resistance to bending. This instinct is not misguided. A corrugated box does feel solid in the hand. Yet its strength is not rooted in rigidity.…
