Sports gear breaks the normal packaging rules. The items are heavy, frequently long, often an awkward shape, and they are usually shipped rather than carried out of a store. That pushes every decision towards structure, and it makes strength ratings worth understanding before you order.
Board strength, in plain terms
Corrugated strength is commonly quoted as ECT, an edge crush measurement that indicates how much stacking force the board tolerates. Single wall board for general shipping is commonly 32 ECT. Heavier goods move to double wall, commonly 44 ECT or above. Triple wall exists for very heavy freight. The higher the rating, the more the box costs and the more it weighs, so the aim is to match the rating to the load rather than to buy the strongest available.
| Construction | Commonly used for |
|---|---|
| Single wall, B or C flute | Apparel, balls, lighter accessories, protective gear |
| Single wall at a higher rating | Moderate weight equipment shipped individually |
| Double wall, BC flute | Weights, heavy or dense items, gear shipped repeatedly |
| Long two piece or telescoping box | Bats, poles, sticks, racquets, anything that will not fit a standard carton |
Long items: use a telescoping box
A telescoping box is two pieces that slide over each other, so one set of tooling covers a range of lengths. For a brand selling several lengths of the same product, that is significantly cheaper than a separate die for every size, and it means an unusual length does not need a new box. The trade off is a slightly higher material cost per unit because you are paying for the overlap.
Empty space is expensive twice
Carriers bill on the greater of actual weight and dimensional weight, which is calculated from the box's outside measurements. An oversized box therefore costs you board on the way in and freight on the way out, on every shipment for the life of the product. It also lets the item move, and movement is what causes damage. Size the box to the item plus the protection you actually need, and no more.
Inserts and protection
Heavy items concentrate their weight in one place, and the corners of a box are where damage starts. Corrugated partitions and fitted board inserts hold the item away from the walls and spread the load. For dense metal items, an insert that stops the item shifting matters more than the wall thickness of the box, because a heavy object with room to slide will punch through any wall eventually. Ask on your quote which protective components we can supply for your item and which you will source separately, so the packing bench is not missing a piece.
Print and retail crossover
If the same box has to sell on a shelf as well as ship, E flute gives you the best print surface among corrugated options, but it is the lightest structure. Many brands solve this with a printed retail carton inside a plain corrugated shipper, which keeps print costs on the piece customers see and strength on the piece the carrier handles.
Ordering large format boxes
The minimum is 100 boxes, including large formats. Pricing starts from about $0.48 per unit at bulk volumes, confirmed on your written quote, and on this category size and board grade move the number more than print does. The cutting die, plates, design support and US shipping are included, and a digital proof is issued before print. Production on the standard lane starts from about 7 business days, with 2 to 5 more for delivery, and the rush and cost saver lanes are quoted per job.
Send the item dimensions
Send the packed weight and the item dimensions to the quote form and we will recommend a construction and a board grade. For board selection background see custom corrugated boxes, and for internal protection see insert packaging and partition boxes.
