Ask about octabin stock
Octabins move in batches tied to resin production runs. Tell us the diameter, height and monthly volume.
Answer first
Rounded corners are the whole point.
An octabin is a bulk container with eight faces rather than four. The geometry does two things: it stops free-flowing material from bridging and packing into a square corner, and it distributes hoop stress around the body instead of concentrating it at four vertical creases. For resin pellets, compounds, powders, granulate, seed and anything else that behaves like a fluid, that is worth considerably more than the extra dollar or two per unit.
The trade-off is cube. A 44-inch round bin on a 48 × 40 pallet holds around 21% less volume than the square gaylord occupying the same footprint. If your material is hand-packed, mixed or non-flowing, the square box is the better buy — and we will tell you so rather than sell you the more expensive option.

Getting more lives out of one
Four habits that double an octabin's working life.
- 01
Discharge without cutting
Tip, vacuum or remove the cap rather than cutting a port. A cut body is a single-use body, and the difference is three or four more trips.
- 02
Keep the base dry
Bases sit on concrete and wick moisture. A slip sheet or a dry pallet is the cheapest life extension available.
- 03
Band before storing
An empty octabin left loose goes oval and never quite squares again. Banded flat, it keeps its geometry indefinitely.
- 04
Send us the rejects
Even a cut body is usually sound board. We will buy it for the cutting table rather than let you bale it at scrap price.

Components
A bin is three products, and they wear out at different rates.
Buying complete sets when you only need bodies is the most common way octabin buyers overspend. We grade and sell all three separately.
- Body
- The eight-sided sleeve, usually triple wall. This is what wears. Cut discharge ports end its life; tipping or cap removal does not.
- Base tray
- Sits on the pallet and locates the body. Frequently outlasts two bodies. Not fully interchangeable between manufacturers — measure yours.
- Telescoping cap
- Protects the top edge and keeps dust and moisture out. Often the longest-lived component of the three.
- Liner
- Round liners, fewer sources than gusseted square ones. Specify the diameter and fill height, not the box size.
- Pallet
- Standard 48 × 40 GMA in almost every case. The base tray spreads load but the pallet still needs to measure true.
- Banding
- Some operations band the body to the pallet for transit. Use corner protection or the strap cuts the top edge.
Discharge
Five ways to empty one, ranked by what they cost you.
How you discharge an octabin decides whether you get two more trips out of it or none. This is the single highest-leverage decision in round-bin handling.
- 01
Remove the cap and tip
Best outcome. No damage to the body, full discharge with the rounded geometry doing the work, three to four more trips available. Needs a tipping frame, which is a one-off cost.
- 02
Vacuum or auger from the top
Excellent for fine material. Body untouched, residual under one per cent, and the bin can be refilled immediately. The standard in compounding operations.
- 03
Lift the body off the base
Works where the base tray stays with the pallet. Slightly awkward with a full bin but leaves both components intact.
- 04
Cut a discharge window, tape it back
A compromise. The body will make perhaps one more trip with a patched window, but the structure is compromised for stacking.
- 05
Cut a full port in the body
Single-trip decision. The bin is finished as a container. Sell us the body for the cutting table rather than baling it — the board is usually perfect.
Materials
What people actually put in them.
Density, flow behaviour and abrasion decide the liner gauge and the wall. These are the combinations we supply most often.
| Material | Density | Wall | Liner | Typical fill | Watch for |
|---|---|---|---|---|---|
| Virgin resin pellets | 32 – 38 lb/ft³ | Triple | 3–4 mil | 1,100 – 1,300 lb | Static in dry winter air |
| Compounded granulate | 35 – 45 lb/ft³ | Triple | 4 mil | 1,300 – 1,500 lb | Contamination between batches |
| Masterbatch | 40 – 50 lb/ft³ | Triple | 4 mil, opaque | 1,400 – 1,600 lb | Light sensitivity on some grades |
| Fine powders | 25 – 45 lb/ft³ | Triple | Antistatic or foil | 900 – 1,400 lb | Dust on fill; charge build-up |
| Mineral fillers | 50 – 80 lb/ft³ | Triple | 5 – 6 mil | 1,600 – 1,800 lb | Abrasion tearing light liners |
| Food ingredients, dry | 30 – 45 lb/ft³ | Triple | Certified foil | 1,100 – 1,500 lb | Documentation before anything else |
| Regrind, fine fraction | 20 – 28 lb/ft³ | Triple | 5 mil | 700 – 900 lb | Sharp fragments cutting the liner |
| Seed and grain | 40 – 50 lb/ft³ | Triple | 4 mil | 1,400 – 1,700 lb | Moisture, always |
Resin volumes are seasonal. Standing orders are not.
