41 x 41 x 48 in bulk bag

A wide base at 48 inches

41 x 41 x 48 = 80,688 cubic inches; / 1,728 = 46.7 cubic feet; x 28.3 = about 1,322 litres. The body is barely taller than it is wide, 48 in against 41 in, so the weight sits low and the bag stands steady on a pallet or on the forks. Where a 35 in bag gets its volume from height, this one gets it from width.

That low profile helps sites with fixed headroom: a fill frame under a beam, a discharger that cannot lift a tall bag clear, or a storage bay with a low ceiling. It holds 4.2 cubic feet more than a 35 x 35 x 60 at 12 in less height.

Animal feed shows why that matters. Pelleted feed, mineral premix and supplements travel to farms and feedlots where the unloading gear is a tractor with forks or a skid steer, not a warehouse truck. A low bag that does not sway on rough ground is the safer one to hand that kind of equipment.

Feed mills cluster where the livestock is: hog and poultry country in Iowa, North Carolina, Georgia and Arkansas, cattle feeding on the southern and central Plains, dairy in Wisconsin, California and New York. Bagged premixes and minerals move from mills to farms in all of them, often on mixed loads.

Pallets: plan on 48 x 48

At 41 in square, the bag overhangs a 40 x 40 in pallet by 0.5 in per side before it is even filled. On a 48 x 40 in pallet it overhangs the 40 in side by 0.5 in and leaves 3.5 in at each 48 in end. On a 48 x 48 in pallet it leaves 3.5 in per side, the only one of the three with room to bulge.

Bales of empty 41 in bags ride fine on a standard pallet; it is the filled bag that needs the wider deck. Tell us the pallet you fill onto and we size around it.

A pallet that is too small does more harm than the overhang figure suggests: the bag's bottom seams sag past the edge, and a tine or the next pallet over can catch them.

Farm storage is seldom a warehouse. Bags sit in machine sheds, under lean-tos and sometimes in the open, so coated fabric, a liner for hygroscopic minerals and a closed top all help, and the UV warning applies in full: bags left in sun for a long spell are not lifted.

Products and ratings

Run the assumed densities through the box: pellets at 34 lb per cubic foot, 1,588 lb; flour at 36 lb, 1,681 lb; seed corn at 45 lb, 2,102 lb; sugar at 50 lb, 2,335 lb; fertilizer at 60 lb, 2,802 lb; cement at 90 lb, 4,203 lb. Gravel at 95 lb would be 4,437 lb and sand at 100 lb 4,670 lb, both over the 4,400 lb top of our rating table, so those fill to the label and stop.

That spread is why the same size turns up at very different SWLs. Feed mills and seed plants fill it at 2,200 to 2,500 lb; mineral and chemical shippers at 3,000 lb or more. Fabric weight, loop strength and seams change with the rating, so the size never tells you what bag it is. The label does.

Some feed and mineral jobs accept once-used bags after inspection, where the product allows it. Anything bound for human food goes in new bags.

Minerals in this footprint include ground limestone, gypsum, bentonite and similar powders and granules, the dry, dense kind of product covered among the 90+ nonfuel minerals in USGS Mineral Commodity Summaries 2026. Each has its own density, often far from our assumed figures, so its data sheet sets the rating.

Fifteen rows of two

In an assumed 53 ft van, two 41 in bags take 82 in of the 100 in width, and 630 / 41 = 15.4, so 15 rows: 30 floor spots. At 2,802 lb of fertilizer, 44,000 / 2,802 = 15 bags. At 1,588 lb of pellets, 30 x 1,588 = 47,640 lb is over the payload, so 44,000 / 1,588 = 27. At a one-ton fill, 22.

A wide, low bag is the steadiest shape to stack in storage, if the label rates it for stacking and the product holds its form. Two of these stand 96 in plus their tops, so check the rack or ceiling as well.
