35 x 35 x 60 in bulk bag
A 35 x 35 x 60 in bulk bag gives 42.5 cubic feet of box volume on a pallet-sized footprint, enough for about 2,125 lb of granulated sugar, 1,913 lb of seed corn or 1,530 lb of wheat flour at our assumed densities. It is the size for medium and light products that need more room than a 50 in bag, usually at 2,000 to 2,200 lb SWL.

Fill weight if filled to the box volume
Each row multiplies 42.5 cu ft by an assumed typical bulk density. A filled bag rounds out and settles, so the real fill differs: use your product's data sheet. Never fill past the SWL on the label.
| Product (assumed density) | Weight at 42.5 cu ft | Lightest common SWL that covers it |
|---|---|---|
| Plastic resin pellets (34 lb/cu ft) | 1,445 lb | 1,500 lb |
| Wheat flour (36 lb/cu ft) | 1,530 lb | 2,000 lb |
| Seed corn (45 lb/cu ft) | 1,913 lb | 2,000 lb |
| Granulated sugar (50 lb/cu ft) | 2,125 lb | 2,200 lb |
| Granular fertilizer (60 lb/cu ft) | 2,550 lb | 3,000 lb |
| Portland cement (90 lb/cu ft) | 3,825 lb | 4,000 lb |
| Gravel (95 lb/cu ft) | 4,038 lb | 4,400 lb |
| Dry sand (100 lb/cu ft) | 4,250 lb | 4,400 lb |

Filled bags on a trailer floor
| Fill per bag | Bags, single stacked |

Assumes a 53 ft dry van 630 x 100 in inside and a 44,000 lb payload; your carrier's limits and the bulge of a filled bag decide.
Sixty inches for lighter product
35 x 35 x 60 = 73,500 cubic inches, which is 42.5 cubic feet or about 1,204 litres. Against the 50 in bag that is 7.1 more cubic feet in the same pallet space. The extra height earns its keep with products under about 50 lb per cubic foot: sugar at an assumed 50 lb reaches 2,125 lb, seed corn at 45 lb 1,913 lb, flour at 36 lb 1,530 lb and resin pellets at 34 lb 1,445 lb.
The density where this box makes a ton is 2,000 / 42.5 = 47.1 lb per cubic foot. Seed corn sits just below that and fills close to 2,000 lb; sugar sits just above and should go in a 2,200 lb bag or stop a few inches short. Those are box sums, and a bag that rounds in the middle holds less, so a test fill on your line settles it.
Food, seed and a clean bag
Sugar, flour and other food ingredients fill this size often, and they bring rules a gravel bag never sees. Food ingredients go in new bags made for food contact, usually with a PE liner, kept clean through storage and transit. We do not quote used bags for food or pharma work. Seed is not food in the same sense, but seed plants want clean, dry bags too, and a lined or coated bag keeps moisture out.
Flour dust is combustible. A bag for flour needs whatever static type your site's hazardous-area assessment calls for; check NFPA 77, IEC 61340-4-4 and the bag maker's documents rather than taking a size page's word for it. If the spec says Type C, the bag has to be connected to ground during filling and emptying, every time, or it gives no protection at all.
Food plants often audit packaging suppliers, and the questions are about the bag maker's facility: whether bags were sewn in a clean area, how they were wrapped, and whether each bale arrives sealed against dust and insects. Ask for the maker's food-contact documents with the quote, and file them with your lot records.
Sugar comes from two directions in the US: beet sugar from the Red River Valley of Minnesota and North Dakota and other northern growing areas, and cane sugar from Louisiana and Florida. Refined product reaches bakeries, confectioners and beverage plants in bags, totes or bulk trucks, and the receiving plant's food-safety program sets the bag spec.
- 2,000 or 2,200 lb SWL, 5:1 single trip for food and seed
- Spout top for closed, dust-tight filling
- Spout bottom with a closure for metered discharge
- Fitted PE liner or coated fabric where moisture or sifting is a concern
- Document pouch for the lot number and product sheet
A tall bag on a 35 in base
At 60 in tall on a 35 in square, the body is 1.7 times as tall as it is wide. A full bag of that shape wants an even fill: one that fills off centre leans, and a leaning bag is hard to set down square on a pallet or a discharge frame. Fill under the centre of the inlet, settle the product with a vibrating table if the line has one, and set the bag down level.
Some lines stand the bag in a holder with corner posts so it is supported while it fills; with a 60 in body on a narrow base, that support is worth having.
Headroom grows with it. Sixty inches of body plus the loops and the top spout has to clear the fill frame's hook bar while the bag sits on the scale. On the discharge side, the frame has to lift the bag's bottom clear of the hopper rim. Measure both before you move up from a 50 in bag.
Weights per trailer
On a trailer the 35 in footprint still gives two across and 18 rows, 36 floor spots in our assumed 53 ft van. At 1,913 lb of seed, 44,000 / 1,913 = 23 bags reach the payload; at 1,530 lb of flour, 44,000 / 1,530 = 28. Both loads are weight-limited before the floor fills. Pellets at 1,445 lb would allow 30.
Receiving matters as much as loading. Bales for a food line should travel in a clean, dry van with no odour or residue from an earlier load, stay wrapped until they reach the filling room, and be stored off the floor. Note torn wrap on the delivery receipt before the driver leaves.
At the receiving end, a food plant empties these bags at a discharge station with a dust hood, often a sealed connection between spout and hopper, and sometimes a device that keeps the liner taut as the bag drains so it does not follow product down. Ask the line which fitting it uses; spout diameter and length must match it.
Questions
How much sugar fits in a 35 x 35 x 60 bulk bag?
About 2,125 lb at an assumed 50 lb per cubic foot, on 42.5 cubic feet of box volume. That is over a 2,000 lb rating, so use a 2,200 lb bag or stop the fill at the label's SWL.
Can 35 x 35 x 60 bags be stacked?
Only if the bag is made and rated for stacking and the product holds its shape. A 60 in body on a 35 in base is tall for its width, so many sites keep full bags single high.
Are used 35 x 35 x 60 bags OK for food?
No. Food and pharma loads go in new bags made for food contact. Used bags are only for non-food loads such as sand or aggregate, after inspection.
