Correct handling and storage protect the performance of industrial dunnage and handling trays from the factory to the packing line. This guide covers stacking, climate, static and inspection.
Everything here can be checked on a real sample before you commit to a production order.
This category covers a family of products rather than a single item. In practice a buyer defines industrial dunnage and handling trays by three things: the base resin, the format or dimension, and the performance or certification level it has to meet. Typical options in this category include gauge 1.5 to 8.0 mm; custom cavity layouts; stack and nest geometry. Materials most often specified are Polyethylene Terephthalate, Acrylonitrile Butadiene Styrene, Polypropylene, Polycarbonate, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the logistics and warehousing sector the decision is usually driven by stackability and returnability, with traceability as a secondary requirement. Typical end uses include picking trays, bakey distribution crates, dunnage trays.
The table below summarises the values that usually decide the material choice.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Acrylonitrile Butadiene Styrene | 1.04-1.06 g/cm³ | 30-50 MPa | -20°C to 80°C |
| High Density Polyethylene | 0.94-0.97 g/cm³ | 20-32 MPa | -50°C to 80°C |
| Polycarbonate | 1.20 g/cm³ | 55-70 MPa | -40°C to 120°C |
Polycarbonate is frequently the default selection here: PC replaces glass where impact safety matters, but it needs a hard coat for abrasion resistance.
Most premature failures are installation issues rather than material failures.
With correct specification and installation, service life in typical indoor conditions exceeds ten years.
Beyond the base resin, most suppliers offer UV stabilised, food contact, flame retardant, anti-static and recycled content versions of the same product. Ask which additive package is included, because it is often the difference between a part that lasts three years and one that lasts ten.
The route below is the one most factories use for this type of part.
Secondary operations such as printing, welding, machining and assembly are often cheaper to do in the same factory, and they reduce the risk of mismatch between components.
These are the criteria that actually predict whether the part will perform in service.
Send this list to your supplier with the drawing and you will receive comparable quotations from every factory you contact.
For standard sizes and colours the minimum is usually one pallet or one production run; for custom tooling the economic minimum depends on the tooling cost amortised over the expected volume. Send us your annual volume and we will calculate the break even point.
We can provide ISO 9001 quality system documentation, material certificates, RoHS and REACH statements, and where applicable food contact, flame retardancy or drinking water approvals. Tell us your target market and we will match the document set.
Standard packing is export cartons on fumigation-free pallets, with custom labelling, barcode and retail packing available. We also handle consolidated containers and door to door delivery.
Standard production tolerance follows the relevant ISO or DIN tolerance class for the process; tighter tolerances are possible after machining or grinding, but they add cost. Define the tolerance only on the functional dimensions.
Colour is controlled with a masterbatch reference approved by the customer, and every production lot is checked against the approved sample under standard lighting before shipment.
Share your specification and quantity with us and we will recommend the most cost effective material, tooling route and packing method for your market.
