Folding field bins with drop doors
A folding field bin is a 48 x 40 in polypropylene bin with a drop door in every wall that folds to about 10 in. It is light for its size, which makes it a good fit for field harvest and for plant work where pickers reach in from any side.

Footprints it comes in
- 48 x 40 in, the size in the table
Options
- FDA-approved colour
- If produce or food touches the walls, ask for the FDA-approved colour and we will confirm the resin in the quote.
- Non-heavy-metal colour
- For buyers whose rules exclude heavy-metal pigments.
- Doors kept shut
- If you don't need all four doors, say so: there is no point paying for doors you will tape shut.
- Lids
- Ask whether a lid is offered for the model we quote; it changes the trailer count.
What the doors are for
A door on every side means the bin can be reached from any aisle. In a field it means pickers can tip a bucket in from any side without the tractor lining it up just so. In a plant it means the last parts at the bottom come out at waist height.
Why the weight matters
At 78 lb empty, a field bin is half the tare of many collapsible containers, which counts on wet ground and against the payload of a loaded truck. The trade-off is capacity: 1,200 lb against the 1,500 lb class. For apples or grapes that is plenty; for metal parts it may not be.
The trip back
Folded to 10 in, 330 of them fit a 53 ft trailer. That is the best return figure of the containers we quote, which is why growers who share bins across ranches like them.
Questions about folding field bins with drop doors
- Is a field bin strong enough for a parts plant?
- For light and medium parts, yes: 1,200 lb is plenty for many components. For castings, stampings and dense scrap, choose a container rated higher.
- Does polypropylene stand up to cold?
- This bin is a high-impact copolymer grade, which is made to keep its toughness. If bins go into freezers, tell us and we confirm the rating.
- Can the doors be locked shut?
- Each door has its latch. If some doors are never used, say so, and we look for a model with fewer.
- Are they safe for produce?
- Ask for the resin statement with the quote; many are made from food-grade polypropylene.
- Why a door in every wall?
- So a picker can reach in from whichever side faces the row or the line, without turning the bin.
- Are they used in packhouses too?
- Yes, often as staging bins along a grading line, where their low height suits hand sorting.
- Weight?
- Light enough to fold by hand.
