An octabin is an eight-sided gaylord. The cut corners resist bulging under dense, flowable loads, so resin, powder and produce are what it is built for. The common size is 46 x 38 x 36 inches inside, on a 48 x 40 inch footprint.
A flowable load pushes outward on every wall. In a square-cornered box the corners take the worst of it and the walls bow. An octabin takes the corners away. The angled panels spread the push around the box, so the box holds its shape while it fills, stands and moves. That is the whole design, and it is why the octabin is the answer for pellets, powders and heavy produce.
The common octabin is 46 x 38 x 36 inches inside. One maker lists the outside dimensions as 47 x 39 1/8 x 37 1/2 inches, 1,300 lb test triple wall, a listed capacity of 2,200 lb and a box weight of 29 lb, and recommends it for resins, powders and produce (source). Another maker's 1300#/ECT-155 triple wall octagon box weighs about 22.9 lb (source). Same size, different build, different weight: ask for the spec of the box you are being offered. The size page has the arithmetic.
An octabin can have a full flap or a partial flap bottom. Resin and produce shippers often choose the partial flap on a slip sheet because it sets up fast. A liner is a separate decision; the liner page covers when resin, powder or food loads need one. Corrugated is not a food-contact surface, and the food guide says why a liner and a clean history are the buyer's call.
Choose the octabin when the load flows and the walls must stay straight. Choose a rectangular box when the load is solid pieces and the stack must be square. The comparison guide puts both side by side.
Send the count, the footprint (octagon on 48 x 40 in), the wall count and what goes in. If you need the box before a harvest or a production run, add the date.
Corrugated bulk boxes were carrying resin and watermelons by the 1950s, and the octagon is the version built for the loads that push hardest (source). Growers use it as a melon, squash and pumpkin bin at harvest, usually with a ventilated partial bottom, and plastics compounders, resin processors and recyclers ask for it by the truckload for pellets and regrind.
One maker lists its 46 x 38 x 36 inch octagon at 29 lb with a 2,200 lb capacity (source), while another lists a 46 x 38 x 36 inch octagon-bottom triple-wall box rated 1300#/ECT-155 at about 22.9 lb (source). The 6 lb gap is why a buyer who is moving many boxes asks which build you have. Say the rating printed on the stamp, not the name on the invoice.
An octabin request should say whether the boxes are lined, what they held, whether the bottom is partial flap on a slip sheet, and whether the lids are included. Resin and produce buyers ask the same four questions, in roughly that order.
An octagonal box can be sold in three states. A lined box carries a polyethylene bag against moisture or dust and is the one plastics and chemical plants ask for. An unlined box is the cheapest to move and suits dry pellets in sealed bags. A ventilated box has cut vents in the sidewalls and is the one growers use for squash and pumpkins. A seller who writes which of the three the stack is has answered half of what a buyer will ask.
The eight-sided cross section spreads load into the corners, which is why the octagon holds a heavy, free-flowing material without bulging. It also means the box sits on a 40 x 48 inch pallet with its corners cut away from the pallet edges, so overhang is rarely a problem.
How tall is your racking opening, since octabins run 36 to 40 inches or more? Are your lids a snug cap or a flat sheet? Does the receiving line tip boxes, or does it lift whole bins with a clamp? Can the ground floor take a stack two bins high without a slip sheet between? Each answer narrows the list of boxes that fit, and each one is quicker to give than to rediscover on delivery day.

Often, yes. Growers use the octagon bin for melons, pumpkins and squash, and the trade also calls it an octagon bulk bin.
One maker lists 2,200 lb for its 46 x 38 x 36 inch octagon bin. Ratings differ by maker and build, so use the rating for the box you actually get.
Count, footprint and wall count are enough to start.
