Slip Sheets vs Pallets: Cost, Weight and Cube per Unit Load
A wood pallet costs $12 to $28, weighs 35 to 50 lb and takes 5.5 inches of height out of every stack; a slip sheet costs $1.50 to $4, weighs under 2 lb and takes almost none, but needs a push-pull attachment at every dock that touches the load. This page compares the two per unit load, works the trailer and container cube, and sets out the situations where each wins.
Slip sheet vs pallet per unit load
A slip sheet is a flat sheet of fiberboard or plastic with a tab on one or more edges. A push-pull forklift attachment grips the tab, drags the whole load onto its platens, and sets it down without a pallet. The load then sits directly on the trailer floor, the container floor, or a pallet at the receiver. The comparison below puts the two on the same footing: one 48 x 40 inch unit load, bought, moved and disposed of once.
| Per unit load (48 x 40 footprint) | Wood GMA pallet | Fiberboard slip sheet | Plastic slip sheet | Corrugated pallet pad (on pallet) |
|---|---|---|---|---|
| Typical purchase cost | $12 to $28 new; $5 to $12 recycled | $1.50 to $4 | $3 to $9, reusable 20+ trips | $1 to $3 per pad |
| Tare weight | 35 to 50 lb (new hardwood 48 x 40) | 1 to 2 lb | 2 to 4 lb | 1 to 2 lb |
| Height added to the load | 5 to 6 in (about 5.5 in typical) | 1/8 in or less (0.03 to 0.06 in sheet plus tab) | 1/8 to 1/4 in | 1/8 to 1/4 in |
| Trailer cube lost to the platform | About 5 percent of a 53 ft trailer single-stacked, 10 percent double-stacked | Under 1 percent | Under 1 percent | Under 1 percent |
| Handling equipment | Any forklift or pallet jack | Push-pull attachment on the forklift at every touch, including the receiver | Push-pull attachment | Standard forklift (sits on a pallet) |
| Rack storage | Yes | No; floor stack or transfer to a pallet | No | Yes, on its pallet |
| Reuse | 5 to 20 trips; returnable pools | Usually single trip | Multi-trip if returned | Single trip |
| Moisture | Absorbs; can mold; ISPM 15 heat treatment for export | Degrades when wet unless coated | Unaffected | Degrades when wet |
| Disposal | Recycle or return; 40 lb of wood | Recyclable with corrugated | Recyclable plastic | Recyclable with corrugated |
The purchase cost line is where slip sheets look best and the equipment line is where they lose. A push-pull attachment costs several thousand dollars per forklift, needs a truck with enough capacity to carry the attachment's weight, and has to be present at every point the load is handled, including the customer's dock. That is why slip sheets dominate in closed loops (grocery distribution, beverage, export to a known receiver) and are rare in open distribution.
Cube: what a pallet costs in trailer and container space
The pallet deck takes about 5.5 inches out of every stack. In a 53 foot trailer with a 110 inch door that is roughly 5 percent of the cube, which is one layer of short cartons per position. In an ocean container the same inch count plus the 40 lb of wood per position is the argument for slip sheets, because container freight is bought by the box, not by the pound.
| Vehicle | Floor positions (48 x 40) | Usable height | Load height on pallets (5.5 in deck) | Load height on slip sheets | Extra cube per vehicle with slip sheets |
|---|---|---|---|---|---|
| 53 ft dry van (110 in door, 13 pallets x 2 rows) | 26 single-stacked, 52 double-stacked | About 108 in | 102.5 in per position (or two 51 in loads) | 108 in per position (or two 54 in loads) | About 5 percent of cube; one extra layer of 5 in cartons per position |
| 40 ft high-cube container (interior 2.69 m high) | 20 to 21 | About 102 in (2.59 m door) | 96.5 in | 102 in | About 5 percent; one extra carton layer |
| 20 ft container | 9 to 10 | About 90 in (2.28 m door) | 84.5 in | 90 in | One extra layer of cartons up to 5.5 in tall |
| Floor-loaded ocean container, cartons only | n/a | Full interior | Pallets rarely used; labor loads loose | Slip sheets allow machine loading where floor loading was the only option | Saves the pallet cube and the pallet weight entirely |
The numbers assume the load is built to the platform height and that stacking strength allows it. A 32 ECT carton on the bottom of a 100 inch stack is carrying everything above it; the pallet loading table gives layer counts for 60 box sizes and the ECT chart gives the grades that survive a tall stack.
When each one wins
| Situation | Use | Why |
|---|---|---|
| Receiver has no push-pull attachment | Pallet | Slip-sheet loads cannot be unloaded without one; the load gets rejected or hand-unloaded at your cost. |
| Export by ocean container, receiver has push-pull | Slip sheet | No ISPM 15 wood, 40 lb less tare per load, and one more carton layer per container. |
| Load will sit in racking | Pallet | Slip sheets have no rigid base; rack storage needs a pallet under them. |
| Stable, uniform cartons, high volume, one destination | Slip sheet | Volume justifies the attachment cost and the receiver can standardize on one unloading method. |
| Mixed cartons, fragile, or top-heavy loads | Pallet | Rigid base resists racking and shear during push-pull moves; stretch wrap alone does not hold an uneven load. |
| Domestic LTL freight | Pallet | LTL carriers handle with pallet jacks at every terminal; slip sheets are not accepted loose. |
| Closed-loop shuttles between two of your own sites | Plastic slip sheet or reusable pallet | Both amortize; plastic sheets cost the least per trip and take no cube. |
| Temporary staging on the floor, no freight | Corrugated pallet pad or pallet paper | Protects the bottom carton layer and adds friction against layer slip without changing the handling method. |
Building a load without a pallet
- Sheet choice. Fiberboard sheets for single trips; plastic (HDPE) sheets where the load is wet, cold, or the sheet comes back. Tab on one edge for trailer loading, two or four tabs where the load is pulled from more than one side.
- Footprint. Cartons should not overhang the sheet; overhanging corners catch on the platens and on the adjacent load. Use column stacking with the bottom tier aligned to the sheet edges.
- Interlayer friction. Push-pull moves shear the load sideways. Anti-slip pallet paper between tiers and a corrugated pad on top hold the tiers together during the pull.
- Unitizing. Stretch wrap the load with three bottom passes that catch the sheet, then corner boards under strapping for anything over 48 inches tall. The stretch film gauge chart covers film weights for loads over 1,500 lb.
- Receiver confirmation. Put the unloading method on the order confirmation. The most common slip-sheet failure is a load arriving at a dock with no attachment.
Stocked load-building supplies
Slip sheets themselves are a quote item by footprint and material. The load-building supplies that go with either method are stocked:
| Stocked item | Role in the load | Examples |
|---|---|---|
| Anti-slip pallet paper (sheets and rolls) | Interlayer friction between carton tiers; stops layer slip on pallets and slip sheets | 37x45 Anti-Slip Pallet Paper Sheets, 80#, 40x48 Anti-Slip Pallet Paper Sheets, 80# Kraft |
| Double wall corrugated pallet pads | Rigid cap or base sheet; spreads strap and wrap load, protects the bottom tier | 24x24" ECT-48 Double Wall Corrugated Sheets, 24x36 ECT-48 Double Wall Corrugated Sheets |
| Edge protectors | Corner posts under strapping or stretch wrap; the main way to stabilize a load that has no pallet | 18x2x2 .225 Fibreboard Edge & Corner, 3x3x60" .120 Fibreboard Edge & Corner |

Frequently asked questions
What is a slip sheet?
A thin sheet of fiberboard or plastic, usually 48 x 40 inches with a tab on one or more edges, that replaces a pallet. A push-pull forklift attachment grips the tab and pulls the whole load onto the truck's platens.
How much does a slip sheet cost compared with a pallet?
Fiberboard slip sheets run about $1.50 to $4 each and plastic $3 to $9, against $12 to $28 for a new 48 x 40 wood pallet and $5 to $12 recycled. The equipment to handle slip sheets costs several thousand dollars per forklift.
Do slip sheets need special equipment?
Yes. A push-pull attachment on the forklift at every handling point, including the receiver's dock. A load on a slip sheet cannot be moved with a pallet jack or a standard fork.
How much space does a pallet take in a trailer?
About 5.5 inches of height per stack, roughly 5 percent of a 53 foot van's cube, plus 35 to 50 lb of weight per position. That is usually one layer of short cartons per position.
Can slip sheets go in racking?
No. A slip-sheet load has no rigid base and must sit on the floor or be transferred to a pallet for rack storage.
