Reusable packaging glossary
Definitions of reusable packaging and returnable asset terms, from asset-level tracking and RTIs to SSCC batching and totes.
Last updated: 29 September 2026
This glossary defines the terms used in reusable packaging and returnable asset logistics, from asset-level tracking to totes. Rotion, a software platform for tracking reusable packaging and returnable assets, uses these terms throughout its documentation. Each definition is self-contained, so you can read one entry or the whole page. Terms are listed alphabetically.
Asset-level tracking
Asset-level tracking follows each individual returnable asset, identified by a serial number or unique code, through its full lifecycle: dispatch, use, return, cleaning, and repair. It answers where a specific crate, keg, or IBC is and who holds it. Rotion combines it with balance-level tracking in one system. See asset-level vs balance-level tracking.
Asset loss (shrinkage)
Asset loss, or shrinkage, is the disappearance of returnable assets from a circulating fleet: crates kept by customers, pallets absorbed into other pools, totes discarded instead of returned. Because losses accumulate quietly between annual counts, loops without asset-level records typically discover the cost only when replacement orders come due.
Balance-level tracking
Balance-level tracking records how many assets each partner holds without identifying individual items. Every delivery and return adjusts a running count per customer or site, much like an account balance. It suits uniform, interchangeable assets such as exchange pallets, where knowing who owes how many matters more than knowing which exact pallet.
Closed-loop system
A closed-loop system is a packaging circuit in which containers circulate among a known set of parties and return to the originator for reuse, rather than leaving the chain after one trip. Deposits, tracking, and defined return points keep the loop closed, and tracking data shows where assets leak out of it.
Deposit return scheme
A deposit return scheme charges a refundable amount on packaging when it is issued and pays it back when the item comes back. The deposit gives the holder a financial reason to return packaging, which raises return rates. Rotion links deposit flows to scans, so balances reconcile automatically. See deposit management.
Digital packaging passport
A digital packaging passport is a digital record attached to a specific piece of reusable packaging, holding its identity, material, ownership, and lifecycle history. Scanning the item's code opens the record. In Rotion, passports carry the data used for reuse reporting and partner accountability. See digital packaging passports.
Digital Product Passport (DPP)
A Digital Product Passport (DPP) is a structured digital record of a product's composition, origin, and lifecycle, planned under EU product regulation to travel with the product itself. For reusable packaging, passport-style records document material and reuse history, which supports reporting under the EU Packaging and Packaging Waste Regulation (PPWR).
Digital twin
A digital twin is a digital representation of a physical object that stays synchronized with the object's real-world state. In reusable packaging, each crate, keg, or pallet gets a digital twin holding its identity, location, condition, and history, updated by every scan. Rotion maintains a digital twin for every tracked asset.
Dunnage
Dunnage is the packaging material used to protect, separate, or brace goods in transit, such as inserts, racks, trays, and separators. Reusable dunnage is engineered for repeated trips, often custom-shaped to a specific part, and circulates between suppliers and plants the same way other returnable transport items do.
Dwell time
Dwell time is how long a returnable asset sits at one location between movements. Long dwell times at customers or depots reduce how often each asset rotates, which raises the fleet size needed for the same delivery volume. Tracking dwell time per location shows where assets stall and who holds them too long.
Exchange pallet (EPAL)
An exchange pallet is a standardized pallet, such as the EPAL Euro pallet, that partners swap one-for-one at handover instead of returning the exact same pallet. Because the pallets are interchangeable, exchange flows are usually managed as balances per partner rather than by individual serial, with disputes settled against the recorded handovers.
Extended producer responsibility (EPR)
Extended producer responsibility (EPR) is a policy approach that shifts the cost of managing packaging at end of life onto the producers who put it on the market. Packaging EPR laws exist in several US states, including California SB 54, and generally treat reusable packaging more favorably than single-use packaging.
GS1 Digital Link
GS1 Digital Link is a GS1 standard that encodes product and asset identifiers into a web address, so one QR code works for warehouse scanners, smartphones, and browsers alike. Scanning the code can resolve to information about that exact item. Rotion uses GS1-compliant identifiers, which keeps asset data portable across partners and systems.
IBC (intermediate bulk container)
An IBC (intermediate bulk container), also called an IBC tote, is a reusable industrial container for transporting and storing liquids and bulk materials, typically a plastic vessel in a metal cage on a pallet base. Returnable IBCs circulate between fillers and customers and are usually serialized for tracking, inspection, and refurbishment.
ISO tank container
An ISO tank container is a standardized stainless-steel tank built within an intermodal container frame, used to move bulk liquids, chemicals, and food ingredients by road, rail, and sea. ISO tanks are high-value returnable assets whose fleets circulate between fillers, cleaners, and depots, making per-tank identity and dwell tracking directly applicable.
Keg tracking
Keg tracking is the practice of following returnable beer and beverage kegs through dispatch, venues, wholesalers, and return. Kegs are long-lived, valuable, and easy to lose in the hospitality chain, so breweries serialize them and scan at handover points. Rotion keeps per-venue balances and per-keg history in one system.
Packaging and Packaging Waste Regulation (PPWR)
The EU Packaging and Packaging Waste Regulation (PPWR) is the EU regulation governing packaging and packaging waste, including obligations around reusable packaging and reporting. For companies running reuse systems, it makes documented tracking of packaging circulation increasingly relevant. See reuse reporting and compliance for how tracking data supports reporting.
Pallet pooling
Pallet pooling is a model in which a shared pool of pallets circulates among many companies, managed by a pooling operator that issues, collects, repairs, and re-issues them. Users pay for pallet use instead of owning a fleet. Pooling contrasts with exchange systems, where partners swap their own pallets one-for-one.
Pooling operator
A pooling operator is a company that owns and manages a shared fleet of returnable packaging, such as pallets, crates, or containers, and rents its use to customers. The operator issues assets, collects them after use, inspects and repairs them, and issues them again. Operators depend on accurate visibility of where pool assets sit across many customers at once.
Returnable container
A returnable container is any container designed to be sent back and used again rather than discarded after one delivery: crates, totes, bins, drums, kegs, and IBCs all qualify. In US usage the term covers what European supply chains often call returnable transport packaging. Tracking who holds each returnable container keeps return rates high.
Returnable transport item (RTI)
A returnable transport item (RTI) is any reusable item used to move or store goods through a supply chain: pallets, crates, totes, kegs, IBCs, roll cages, and reusable dunnage. RTI is the common European term; US buyers more often say returnable containers or reusable packaging. RTIs are assets, so loss and slow rotation carry direct cost.
Reusable plastic container (RPC)
A reusable plastic container (RPC) is a rigid plastic crate or tote designed for repeated trips, widely used in fresh produce, bakery, and retail distribution. RPCs typically fold or nest to save space on return transport. They pass through wash cycles between uses and are tracked individually or per batch, depending on value.
Reverse logistics
Reverse logistics is the part of the supply chain that moves goods from their destination back toward the origin: returns, collection of empty packaging, washing, and redistribution. For reusable packaging, reverse logistics is where loss and delay concentrate, because empty assets rarely get the attention that outbound goods do.
Rotation (reuse cycle)
A rotation, or reuse cycle, is one complete trip of a reusable asset: issue, use, return, and preparation for the next issue. The number of rotations an asset completes over its life drives the economics of reuse, since each cycle spreads the asset's cost over one more delivery. Faster rotation means a smaller fleet does the same work.
SSCC (Serial Shipping Container Code)
An SSCC (Serial Shipping Container Code) is a GS1 identifier for a logistics unit such as a loaded pallet, cage, or shipment. One SSCC scan registers the whole unit at a checkpoint. Rotion uses SSCCs to batch assets, so groups scan as one while each item stays traceable. See SSCC batching.
Tank (returnable)
A returnable tank is a reusable bulk container for liquids or granulates, from IBC totes to dedicated tank fleets and railcars, that cycles between filling, delivery, emptying, and cleaning. Tank fleets concentrate high value in few assets, so per-asset history, cleaning records, and holder accountability carry more weight than with low-value packaging.
Tote
A tote is a rigid, reusable container used to move goods through warehouses, stores, and delivery routes, usually stackable or nestable plastic. Totes circulate between distribution centers, stores, and suppliers in retail and e-commerce loops. In US usage, tote also covers the IBC tote, which is an intermediate bulk container for liquids.
Unit load device (ULD)
A unit load device (ULD) is a returnable air-cargo container or pallet used to load baggage and freight onto aircraft. ULDs circulate between airlines, ground handlers, and freight forwarders in a classic multi-party loop, where per-asset identity and holder history determine who is accountable for damage and loss.
