How to Choose Plastic Totes for ASRS and Automated Warehouses
Updated: Jul 30
Choosing an ASRS tote is not a simple container purchase. The tote becomes part of the automation system: conveyors, lifts, shuttles, robots, sensors and storage locations all depend on consistent geometry and predictable handling. A low-cost bin that flexes, jams or scans poorly can create far more operational cost than it saves.
This guide gives North American warehouse, integrator and procurement teams a practical way to compare options before ordering production quantities.
Start with the automation envelope—not the catalogue photo
Begin with the dimensional limits supplied by the automation integrator. Record the maximum outside length, width and height, but also the base contact area, conveyor clearances, lift points, tote orientation and required tolerances. Two totes with the same nominal footprint may behave differently because their base ribs, corner geometry or rim profiles are not the same.
If your system is designed around a common modular footprint such as 600 × 400 mm, confirm the exact external dimensions and tolerance range rather than assuming every “Euro-size” tote is interchangeable.
Seven specifications that matter in an automated warehouse
1. Base design: The base must travel smoothly across the actual conveyor, roller spacing, transfer plates and curves. Ask whether a smooth, reinforced or specialized base is recommended for the equipment.
2. Rigidity and deflection: A tote should keep its shape under the expected payload and stacking conditions. Excessive bottom sag can affect sensors, transfers and storage location accuracy.
3. Rim and lid interface: Check how the rim is gripped, guided and stacked. If lids are used, confirm clearance, hinge placement and whether the lid changes the overall height.
4. Identification: Plan barcode, label, RFID or in-mold identification locations early. The reading surface should remain visible, flat and protected through the operating cycle.
5. Interior configuration: Dividers, inserts and dunnage must secure the product without interfering with automated handling. Allow for picking access and return flow.
6. Environment: Document temperature, humidity, cleaning chemicals, dust, static-control requirements and exposure to oils or coolants. Material selection should follow the real operating environment.
7. Service life and repair policy: Compare more than unit price. Include expected trips, damage rate, replacement availability, cleaning time and the cost of interruptions.
Use payload data that reflects reality
Separate maximum product weight from the way that weight is distributed. A compact metal component applies load differently from lightweight parts spread across the base. Tell the supplier whether the tote will be supported at the corners, along two rails, across rollers or on a full shelf. Also document dynamic loads created by acceleration, stops and transfers.
For tall or partially filled totes, consider product movement and the centre of gravity. Internal dividers or custom dunnage may improve both part protection and automation reliability.
Design for scanning and traceability
Decide where identification will be applied and how many sides must be readable. Label recesses can reduce abrasion, while standardized placements make camera and scanner setup easier. If RFID is planned, validate the tag, placement and read zone with the actual contents; metal parts and liquids can affect performance.
Validate a sample in the real system
A drawing review is necessary, but a controlled trial is the best way to uncover issues. Test representative samples through straight conveyors, curves, lifts, transfers, storage positions and workstations. Use the heaviest and most awkward payloads, not an empty tote.

Measure deflection and dimensional change after repeated cycles.
Confirm reliable sensor detection and barcode or RFID reads.
Check stacking, destacking, lid operation and manual handling.
Record jams, noise, vibration and product movement.
Run cleaning and temperature tests when those conditions are part of the process.
When a standard tote is not enough
Standard sizes are often the fastest and most economical starting point. Customization becomes valuable when the automation interface, payload protection or traceability requirement cannot be met reliably with an off-the-shelf container. Options may include custom dimensions, reinforced bases, drainage, label areas, dividers, dunnage or dedicated mold development.

The best ASRS tote is the one that performs consistently in your equipment, with your payload, across the full operating cycle.
Prepare a useful RFQ
For a faster technical review, include the required dimensions and tolerances, payload and distribution, base support conditions, equipment type, operating temperature, identification method, annual quantity, colour, lid or divider needs and any applicable testing or documentation requirements.
