Custom heavy-duty carton — made to order: size, flute, board grade and reinforcement are all specified per run.
When a carton has to survive an export route rather than a courier run, the answer is more board rather than more tape. Double- and triple-wall construction, AB or BC flute combinations and reinforced corners take compression strength to 5 of 5 — enough for equipment, machinery parts and anything that will be stacked, forked, containerised and handled again at the other end.
Where the failures actually happen
Boxes rarely fail in the middle of a panel. They fail at the corners, where the load concentrates, and at the top edge, where a forklift or another pallet meets them. That is what reinforced corners are for, and it is why the flute combination matters as much as the total thickness — AB and BC pair a cushioning flute with a crush-resistant one so the box does both jobs rather than one well.
Ordering
Size, flute, board grade and reinforcement are made to order. Typical uses are heavy equipment, export shipments and long-distance logistics. For loads timber would normally take, the honeycomb board box gets close to the same strength without the weight or the fumigation paperwork — and where nothing lighter will do, see wooden case and pallet.
What moves the price
Board, and a lot of it. Double and triple wall carry two and three times the material of single wall, and the flute combination adds to that. Reinforced corners are an additional operation. Against timber the comparison is usually favourable on both cost and weight; against ordinary corrugated it is a step up that should be justified by the route rather than by caution. Quantity and print behave as with any carton.
Where it goes wrong
Specifying triple wall where double wall and corner protectors would do, which is a common and expensive over-correction after one failed shipment. The second is relying on the box while the goods move inside it — bracing and cushioning do as much as the wall count. The third is forgetting that a heavy carton is also a heavy carton to lift, and a load that needs two people to handle will be handled badly.
Where custom heavy-duty carton is used
Machinery parts, equipment, export consignments and any load that will be stacked, forked and handled again at the other end. Where the requirement is really strength rather than paperwork, compare it against the honeycomb board box on weight and against wooden cases on cost. What the export set has to contain either way is in export packaging compliance.
What to send us for a quotation
A quotation for custom heavy-duty carton is written against a specification, so the more of this you can send, the closer the first number is to the real one: which structure, or the shelf life and the product so we can choose one — Heavy corrugated board are available here; the temperature the pack has to survive, from filling through to how the customer opens it (ambient for this product); the line it runs on — this one is specified for die cutting and Strapping and taping; which options you want fitted: double wall, Triple wall and AB flute; the values for size, Flute, Board grade and Reinforcement.
Send the fill weight and the quantity with it. Where you already buy something similar, a sample is worth more than a description — we measure what is actually there rather than quoting against how it was once written down.
Food-contact and export requirements are set out in ISPM 15, the international standard for wood packaging crossing a border; the declarations for this structure are issued with the order.
