Pallet
Pallet is a flat load base built so forklifts, pallet jacks, and AGVs can lift a unit load as one object. Wood, plastic, and metal pallets all share the same job: hold stacked cartons, totes, or fixtures and survive repeated dock and aisle handling. Common footprints include the Euro pallet (1200 × 800 mm) and North American GMA sizes such as 48 × 40 in.
Plants and warehouses treat the pallet as the default move unit. A barcode or RFID on the pallet ID often drives WMS putaway and shipping. When that load leaves its bay without a system update, search and find starts with the pallet ID, not every carton on top.
Pallets can be plant-owned, supplier-owned, or rented from a pool. Pool pallets are classic returnable packaging. Cheap one-way wood that leaves with the customer is closer to one-way packaging and is a poor host for expensive continuous-location tags.
Key Components
Deck and stringers or blocks: The top face that carries the load and the under-structure that opens for forks from two or four sides.
Footprint and rating: Length, width, and safe static or dynamic load. Mismatched footprints break trailer and racking plans.
Material: Wood for low cost and repairability, plastic for wash and hygiene, metal for heavy or high-cycle loops.
Identity: Stencil, barcode, RFID, or RTLS tag that systems use as the unit-load ID.
Ownership model: Plant stock, supplier stock, or shared pool with deposit and return rules.
Applications in Manufacturing and Logistics
Inbound receiving builds pallet loads at the dock. Internal logistics moves those loads to buffers and line-side. Shipping rebuilds outbound pallets for carriers. Across all three, the pallet is the object scanners and drivers already name.
Location projects often tag high-value or frequently lost pallets, or the returnable cage sitting on them, rather than every SKU. Medium-precision RTLS is enough to say which aisle or buffer holds the pallet. Gate reads confirm which pallet IDs left the building. That picture feeds the twin used for internal logistics optimization.
Benefits and Challenges
The benefit is a universal handling interface. One forkable base moves mixed product with standard equipment. Durable plastic or pool pallets can carry identity for years.
The challenge is quality and pool leakage. Broken boards jam conveyors. Pool pallets leave with carriers and never return. Heat-treated export stamps and hygiene rules add constraints. Tagging every expendable pallet rarely pays when the wood never comes back.
Related Terms
Cage, rack, and stillage often ride on or replace a bare pallet for protected parts. Corrugated cartons and plastic totes stack on the deck. Returnable packaging covers pool pallets. Asset tracking treats the pallet as the tracked unit when the ID stays with the load.
Frequently Asked Questions
Is a pallet the same as a stillage or rack? No. A pallet is the flat base. A stillage, rack, or cage is usually a framed or enclosed unit that may sit on a pallet or include fork pockets of its own.
Should every pallet get an RTLS tag? No. Prefer durable returnable pallets with high hunt or miss cost. One-way shipping pallets are better tracked by gate events or process tags that leave with the load.
Euro pallet versus GMA: does it matter for location? Yes for handling and trailer fit. Location tech does not care about footprint, but your dock and racking layout does.
Wood or plastic for tagged fleets? Plastic and metal usually hold mounts and wash cycles better. Wood works when repair shops and ID discipline stay strong.
