How empty and filled bags travel
New empties leave the factory folded flat and pressed into bales, strapped tight and often wrapped. Bales are then stacked onto pallets and stretch-wrapped, so a carrier sees a few dense cubes rather than loose fabric. Used empties coming back from a fill line are usually folded and baled too, or stacked flat on pallets, before a pickup.
How many bags make a bale, and how many bales sit on a pallet, depends on the size, the fabric weight and the maker's press. Ask for both counts on the quote. They are the numbers that turn an order of bags into an order of pallets, and pallets are what freight is priced on.
A filled bag is heavy and its shape is fixed by the fill. Most go one high on the trailer floor, sometimes on pallets, sometimes directly on the deck, loaded by forklift through the rear doors. Baffle bags stay squarer and pack tighter. Stacking two high on a truck is a decision for the bag maker's documents and the carrier, never a default.
Both empties and filled bags normally move in enclosed dry vans, which keep weather off the fabric. An open flatbed exposes bales to rain and sunlight. A refrigerated unit is worth paying for only when the product inside, not the bag, requires temperature control.
Freight class and density, in plain terms
LTL carriers price shipments using freight classes. For many goods the class is driven largely by density: the weight of the shipped piece divided by the space it takes. Lighter, bulkier freight sits in a higher class and costs more per pound. Handling, stowability and liability can also affect it.
Here is how density is worked out, with an assumed pallet. A pallet stacked 48 x 40 x 50 in occupies 96,000 cubic inches, and 96,000 / 1,728 = 55.6 cubic feet. If that pallet of bales weighed an assumed 500 lb, its density would be 500 / 55.6 = 9.0 lb per cubic foot. Your real figures come from the scale and tape at the shipper. The carrier's tariff decides the class.
A full truckload is priced differently: you hire the trailer for the lane, usually without class, so density stops mattering as long as you stay under the legal weight.
Trailer floor arithmetic
Our size pages use an assumed 53 ft dry van with an inside floor of 630 x 100 in and a payload of 44,000 lb. Bags across the width is 100 divided by the bag's width, rounded down. Rows down the length is 630 divided by its depth, rounded down. The weight limit is 44,000 divided by the fill weight. Whichever is smaller wins.
| Example (single stacked) | Working |
|---|---|
| 35 x 35 in footprint, 2,000 lb fill | 100 / 35 = 2 across; 630 / 35 = 18 rows; 2 x 18 = 36 by floor. 44,000 / 2,000 = 22 by weight. Load: 22 bags. |
| 41 x 41 in footprint, 1,500 lb fill | 100 / 41 = 2 across; 630 / 41 = 15 rows; 2 x 15 = 30 by floor. 44,000 / 1,500 = 29 by weight. Load: 29 bags. |
| 41 x 41 in footprint, 1,000 lb fill | 30 by floor; 44,000 / 1,000 = 44 by weight. Load: 30 bags, floor-limited. |
When a full trailer makes sense
Two pallets of bales ride LTL without fuss. Once the count climbs toward a trailer's worth, one booked truck usually costs less per bag than several LTL moves, and it arrives as one delivery rather than pieces on different days. The catch is storage: a truckload of empties needs a dry, covered spot inside, off the floor, until the fill line uses them.
- LTL suits trial orders, samples, a short top-up, or sites with little floor space.
- Truckload suits steady fill lines, seasonal peaks you can forecast, and outbound filled product.
- Scheduled releases split one large order into several truckloads over time.
- Mixed specs can share a trailer when they ship from the same origin.
Storage trade-offs
Buying a trailer at once moves cost from freight into your building. Bales take up floor that could hold finished goods, and money sits in stock instead of in the bank. Bags kept too long meet forklift scuffs, heat and stray sunlight from open doors. Against that, a deep stock cushions a missed truck or a sudden spike in orders.
A practical middle path: hold enough to cover the gap between deliveries plus a safety margin you choose, and let releases bring the rest. Seasonal fillers, such as seed or fertilizer packers before planting, often take bigger loads ahead of the rush and smaller top-ups afterward.
Signing for the freight
The bill of lading names the shipper, the consignee and the pieces. Count pallets against it before the driver leaves. Torn wrap, crushed bales or wet corners get written on the delivery receipt with a photo, because a receipt signed clean makes a later damage claim very hard to win. Shortages and overages work the same way.
Ask about accessorial charges in advance. Liftgate service, inside delivery, residential or limited-access stops, appointment fees and driver detention all show up on LTL invoices if they were not booked. Knowing them up front keeps the final bill close to the quote.
Dock and liftgate questions to answer first
Most failed deliveries are a receiving problem rather than a freight one. Before we book, we need to know whether you have a dock at trailer height or ground-level doors only. Without a dock, LTL needs a liftgate and maybe a pallet jack on the truck, which the carrier charges for and which limits pallet weight. A full truckload generally needs a dock or a forklift able to reach into the trailer.
Tell us receiving hours, whether appointments are required, any length limits on the street or yard, and the forklift you use. A residential or limited-access address changes the booking too. These answers stop a truck from arriving and leaving with the freight still aboard.
A refused or failed delivery is expensive twice: the carrier bills a redelivery or storage at its terminal, and your fill line waits. Ten minutes on the phone describing the gate, the doors and the unloading equipment is the cheapest insurance in the whole order.
Questions
Can you promise a delivery date?
We do not promise windows. We book the lane, give you the carrier's estimate, and pass on appointment details as soon as they exist.
Is it cheaper to ship more bags at once?
Per bag, usually yes, up to a full trailer. The saving only counts if you have dry indoor space to hold the extra stock.
Do filled bags ever go LTL?
They can, a few at a time on pallets, but heavy filled bags reach LTL weight and handling limits fast. A dedicated truck is more common.
Who decides the freight class?
The carrier's tariff and the measured shipment do. We give the carrier accurate weights and dimensions so the bill matches the quote.
Can empties go back on the truck that delivered?
Sometimes, if the timing and the lane line up. Ask when you book; otherwise we arrange an empties pickup separately.
