Stackable plastic pallet: built for floor stacking
A stackable plastic pallet has a continuous bottom (runners or a perimeter frame) that spreads load onto the floor or the goods below, so loaded pallets can be block-stacked. It sits between nestable pallets (lighter, cheaper) and rackable pallets (reinforced for beams). Many are not rated for racking.
"Stackable" describes a plastic pallet built for block stacking: loaded pallets placed directly on top of each other on the floor. It is a common choice in closed-loop operations that floor-store rather than rack.
What is a stackable plastic pallet?
A stackable plastic pallet has a bottom structure of runners or a perimeter frame that carries the load down onto whatever is below: the floor, or the load on the pallet underneath. Distributor catalogs sort plastic pallets by bottom function into three groups: stackable, rackable and nestable. See block stacking.
How is a stackable plastic pallet built?
| Feature | Typical |
|---|---|
| Deck | Open or closed |
| Base | 3 runners, 6 runners, or perimeter (picture frame) |
| Entry | 2-way for pallet jacks with runners in one direction; 4-way with a perimeter base |
| Height | about 5–6.5 in (127–165 mm) |
| Reinforcement | Usually none; add-on in some models |
| Empties | Stack flat 1:1 (no nesting) |
The continuous base is the key difference from a nestable pallet. Instead of nine small feet pressing into the load below, runners or a frame spread weight along lines or around the perimeter, which protects cartons and lets taller stacks stand safely.
Where are stackable plastic pallets used?
- Block-stacked floor storage in warehouses without racking
- Closed-loop shipping between plants
- Double-stacked loads in trailers
- Conveyor systems that need a continuous bottom
- Food and beverage operations that need washable pallets but not racking
Pros and limits
| Pros | Limits |
|---|---|
| Spreads load for block stacking | Heavier than nestable pallets |
| Conveyor friendly | May not be rated for racking |
| Very high static ratings | Empties stack 1:1, so return freight costs more than nestable |
| Washable, long life | Costs more than nestable |
| ISPM 15 exempt | Runner models may be 2-way for pallet jacks |
Capacity and weight
Static ratings for stackable plastic pallets are high. One published 40 × 48 in stackable model is rated 30,000 lb (13,608 kg) static and 4,000 lb (1,814 kg) dynamic. The static rating applies to the bottom pallet on a flat floor under a uniform load. In practice the limit on stack height is usually the load, not the pallet: cartons crush, bags shift and stacks lean. Weight varies by model, typically between nestable (20–30 lb) and rackable (35–55 lb) pallets. See pallet load capacity and pallet stacking patterns.
If a stackable model has no racking rating, do not rack it. Ask for a rackable model instead.
Nestable, stackable or rackable?
| Need | Choose |
|---|---|
| Lowest price and compact empties, floor or fork use only | Nestable |
| Loaded pallets block-stacked on the floor, conveyors | Stackable |
| Open-beam racking | Rackable |
| Washdown in food or pharma | Hygienic, which can be stackable or rackable |
The same manufacturer often sells one footprint in all three bottom styles. Start from how the pallet will be supported, then pick the lightest style that meets it.
ISPM 15
Plastic pallets are exempt from ISPM 15.
What drives the cost?
As an indicative 2026 US range, new stackable 48 × 40 in plastic pallets cost about $60–120. Drivers:
- Resin weight and type
- Runner count or perimeter base
- Open or closed deck
- Colour, branding, RFID
- Freight (empties do not nest)
- Quantity
Specifying a stackable plastic pallet for a quote

- Base: runners (how many, which direction) or perimeter
- Entry: pallet jack access from which sides
- Load weight per pallet and stack height
- Minimum static and dynamic ratings
- Racking: none (or state if needed, which points to a rackable model)
- Conveyor direction

Frequently asked questions
What is the difference between stackable and rackable plastic pallets?
Both have a continuous base. A rackable pallet is also stiff enough, often with steel reinforcement, to span rack beams and carries a racking rating. A stackable pallet is designed for floor stacking and may not be rated for racking.
What is the difference between stackable and nestable plastic pallets?
A nestable pallet has legs that fit into the pallet below when empty. A stackable pallet has runners or a frame, so empties stack flat on top of each other (1:1) rather than nesting.
How high can stackable plastic pallets be stacked?
It depends on the pallet's static rating, the weight of each load, and the strength of the goods, which usually limits first. Divide the static rating by the weight above the bottom pallet as a first check, then confirm with the manufacturer.
Can stackable plastic pallets go on conveyors?
Usually yes. Runners or a perimeter base give rollers a continuous surface; perimeter bases convey in both directions.

- TypesPlastic pallets: types, materials, load ratings and how to buy themA plastic pallet is a molded or fabricated pallet made from HDPE or polypropylene. Types range from light nestable pallets (about 14–30 lb) to reinforced rackable pallets (about 35–70 lb). They are washable, ISPM 15 exempt and long-lived, cost several times more than wood, and carry three separate load ratings.
- TypesRackable plastic pallet: runners, reinforcement and racking ratingsA rackable plastic pallet is designed to sit in open-beam racking with nothing underneath. It has runners (3, 5 or 6) or a perimeter or cruciform base, often with steel reinforcement. Racking ratings for 48 × 40 in models are typically about 1,500–4,400 lb, valid only at the tested span and orientation.
- TypesNestable plastic pallet: light, cheap and not for racksA nestable plastic pallet has legs or feet, usually nine, that fit into the pallet below when empty, so stacked empties take little space. It is the lightest and cheapest plastic pallet, about 14–30 lb (6–14 kg) in 48 × 40 in, with 4-way entry. It is not rackable.
- GlossaryBlock stackingBlock stacking is storing unit loads directly on top of one another on the warehouse floor, in rows and columns, with no racking. The bottom pallet and the packaging carry the whole stack, so static load and box compression strength limit the height.
- GuidesPallet stacking patterns: column, interlock, pinwheel and brickColumn stacking puts each box directly on the box below and keeps the most compression strength. Interlocking patterns (brick, pinwheel) rotate alternate layers so boxes overlap, which adds stability but can cut stacking strength sharply. Many loads use columns with tie sheets, or interlock only the top layers.
- GlossaryStatic loadStatic load is the weight a pallet can safely carry while sitting stationary on a flat, solid floor, including the load from unit loads stacked on top of it. It is the highest of a pallet's ratings because the floor supports the whole bottom deck.
- ComparisonsNestable vs rackable plastic pallets: differences and when to use eachChoose a nestable plastic pallet for floor stacking, one-way export and closed loops where cheap return freight matters, since empties nest into each other. Choose a rackable plastic pallet, with runners or a perimeter base and often steel reinforcement, when loaded pallets sit on open rack beams.
