Slip Sheet
A slip sheet is a thin, pallet-size platform made of fiberboard, corrugated board, solid board, or plastic that supports a unitized load and replaces a conventional pallet. It has no fork-entry structure; a forklift equipped with a push-pull attachment grips the sheet's lip and slides the load onto its platens for transport and storage.
On the shop floor and in distribution, slip sheets replace pallets wherever tare weight, cube, cost, or return logistics become a problem. Loads are built directly on the sheet, stretch-wrapped, and moved with a push-pull fork attachment that grips the exposed lip. This creates a palletless handling unit that allows cartons or bagged goods to fill a trailer or container more densely and reduces shipping weight. Inbound slip-sheet shipments require the receiving site to have a compatible push-pull carriage and trained operators; otherwise the dock stalls. Warehouses use them in high-volume export lanes and dense storage where wood pallets are prohibited or expensive. The WMS must flag slip-sheet handling units so receiving, putaway, and picking know the load cannot be dropped on conventional rack without transfer equipment. Inventory tracking still uses handling units, but material handling constraints need to be embedded in master data and dock schedules to avoid disruptions.
What is the key mechanical difference between a slip sheet and a pallet?
A slip sheet has no forklift-entry structure of its own; it is moved by a push-pull device that clamps or hooks the lip and slides the load onto platen surfaces.
Why do manufacturers use slip sheets instead of pallets?
To reduce unit-load tare weight, improve container cube utilization, lower pallet purchase cost, and avoid pallet-return or wood-treatment constraints in export flows.
How does slip-sheet use affect inventory tracking?
In WMS/ERP terms, the unit load still behaves like a transport handling unit, but the location, equipment requirement, and packaging master data must explicitly identify it as slip-sheet compatible to prevent receiving exceptions and mis-routed putaway.
