Plastic bulk bins and pallet boxes
Plastic bulk bins and pallet boxes are rigid, fixed-wall containers molded to sit on a forklift-ready base, built to hold heavy, dense or wet loads that would push out the sides of a folding box. Food plants, processors and parts makers use them for ingredients, trim, castings and anything that stays in one building or travels a short loop.

What makes a fixed-wall bin different
There are no hinges, latches or loose panels: walls and base come out of the mold as one part. That gives a bin two advantages over a collapsible bulk container. The sides resist outward pressure from loose, high-density contents, and nothing can be left unlatched. ORBIS says its fixed-wall HDRS models support heavy, dense components. Buckhorn calls its fixed wall line stack-only tubs.
The cost shows up on the empty trip. ORBIS lists its HDRS4845-21 at a 1.0:1 return ratio and Buckhorn its BF48442900 at 1:1, meaning an empty bin takes the same space as a full one. If empties go back hundreds of miles, run the numbers in the trailer fill tool before choosing this style.
Walls, floors and bases
Solid or vented. Solid sides and floor hold liquids, brine, fines and powders; IPL Schoeller's MacroBin 44 Solid adds double-wall construction and is aimed at food, beverage and industrial uses including refrigerated or frozen products. Vented bins let air through for cooling produce; those are covered on macro bins and harvest bins.
Runners, legs or skids. The base decides how a bin meets forks, conveyors and racking. Craemer lists its CB3 pallet box with three runners, which suit roller conveyors and rack beams; IPL Schoeller offers wheels and skids as accessories on its rigid pallet containers. Lids and doors. Buckhorn sells an optional lid for the BF48442900, IPL Schoeller makes secure-fitting MacroLids for its solid bins, and its rigid pallet range lists doors too, with UN-certified versions for hazardous goods.
Dumping. Many processors empty bins by tipping them with a hydraulic dumper or a rotating fork attachment, which grips the base or walls and inverts the load into a hopper. A bin that fits one dumper's cradle may not fit another's, so send us the dumper or rotator make along with the bin size. Smooth inside corners also help sticky product slide out cleanly.
Fixed-wall bin models
These cover the main families we quote, from automotive tubs on 48x45 to deep food-plant bins and long boxes on 56x48 and 64x48. Values are taken from each maker's page. IPL Schoeller titles its 44 and 48 pages MacroBin but calls the product ProBin in the text; we use the page title.

Reading the claims
IPL Schoeller calls the MacroBin 48 Solid "the world's largest fixed-wall, high-pressure injection-molded bin." That is the maker's description, and we pass it on as such. Buckhorn's page for the BF48442900 names a different model in its description and gives two slightly different lid part numbers, which looks like a typo; we confirm the lid number with the maker before quoting it.
Ratings vary widely across this family. Buckhorn rates a 48 x 44 transport tub at 700 lb while ORBIS rates its shorter 48 x 45 fixed-wall box at 2,000 lb, and Craemer gives separate holding and dynamic figures in kilograms. Match the figure to how the bin is used: sitting on a floor, stacked in a cooler, or moving on a truck. See stacking limits.
Where bulk bins are used
Buckhorn describes its fixed wall tubs, in 42 x 29 and 48 x 44 in footprints, for produce from harvest through retailing. IPL Schoeller points its solid bins at food processing and storage, and our food processing, meat and poultry and seafood pages cover in-plant uses such as trim, brining and ingredient staging. In manufacturing, a fixed-wall box takes stampings, machined parts and scrap that would bulge a folding wall. IPL Schoeller also lists beverage among the uses for its double-wall MacroBin 44 Solid.
On food contact, Buckhorn says its fixed wall containers are "manufactured out of FDA-compliant materials." That is Buckhorn's statement about new product. We don't certify bins, new or used, for food; ask for the maker's document and tell us the bin's history.
Used bins and what to send for a quote
Fixed-wall bins last, so used lots are common, often from plants that changed products or consolidated. Our used bulk bins page covers where they come from, and grades A, B and C are defined in used container grades. On samples, look under the bin: cracked runners or legs, gouged fork openings and a sagging floor all cut capacity. Check corners for stress whitening, drains for blockage, and walls for residue or odor from earlier contents.

Questions
Should I buy fixed-wall or collapsible?
Fixed-wall for heavy, loose or wet loads on short loops; collapsible when empties travel far. The deciding numbers are return distance and how dense the load is.
Do fixed-wall bins nest?
Most don't; they stack, and an empty takes the room of a full one. If empty space matters, tell us, and we'll look at nesting rigid designs or a collapsible instead.
Can a bulk bin go in a freezer?
Some are built for it. IPL Schoeller says its MacroBin 44 Solid suits refrigerated or frozen products, and Buckhorn rates its fixed wall line for -20 to 120 F. Check the model's range.
