A honeycomb box is made from panels rather than from a folded blank, and that changes what the panel has to do. Each wall is a structural member, the corners carry the stack, and the base takes the whole load through the pallet. The panel specification is therefore driven by the box dimensions and the stack height, not by the product alone.
Why a heavy box is built from panels
A corrugated blank folds into a box because the board is thin and the folds do the work. Above a certain size and load, the blank becomes impractical: the walls bow, the base sags and the box needs internal blocking. A honeycomb panel box is assembled from flat walls, so each wall can be specified for the load it carries.
The trade is assembly time. A panel box is glued, stitched or strapped at the corners, which is slower than folding a blank, and that labour has to be counted against the material saved.
Specification at a glance
Box walls are typically 15-30 mm, with the base one step heavier than the sides because the base carries the stack through to the pallet.
| Box part | Thickness | Core cell | Driver |
|---|
| Side wall, up to 1 m | 15-20 mm | 4-6 mm | Stack height |
| Side wall above 1 m | 25-30 mm | 4 mm | Corner joint strength |
| Base on a pallet deck | 25-30 mm | 4 mm | Load through the deck |
| Base spanning bearers | 30 mm or doubled | 4 mm | Span between bearers |
| Lid | 15-20 mm | 6 mm | Stacking and skirt depth |
Dimension, stack height and the base panel
Tall boxes fail at the corner joint first, because the joint takes the horizontal component of any lean. A 20-25 mm panel with a 4-6 mm cell gives the joint enough edge area to bond or strap. Thin panels with a large cell crush at the joint and the box racks.
The base panel should be the heaviest in the box and should sit on the pallet deck, not on a corrugated flange. Where the base spans between pallet bearers, the span is what decides thickness, not the product weight.
Assembly and closure
Corners are usually bonded with a paper or plastic angle, or stitched. Bonded joints need a dry, clean panel edge; a dusty cut face is the most common cause of a joint that opens in transit.
Lids are often a single panel with a skirt. Where the box will be stacked, the lid should bear on the walls rather than on the product, and the skirt should be deep enough that the lid cannot walk off during handling.
Questions buyers ask before ordering
Can you supply the assembled box?
We supply the panels and the die-cut components. Assembly is normally done by the converter or at the packing site, and we can discuss a flat-pack kit.
How is a honeycomb box closed at the corner?
Bonded with a paper or plastic angle, stitched, or strapped. The joint design should be agreed with the panel thickness.
What thickness for a 1.2 m tall box?
25-30 mm with a 4 mm cell is the usual starting point, then confirm against the stack height and the corner detail.
Is a honeycomb box lighter than plywood?
Yes, for the same wall thickness, which is the main reason to use it. Where point loads are severe, a plywood base is still the safer choice.
Can the panels be printed?
Yes, on the facing paper, subject to artwork and print method.
