Top Applications of PP Industrial Dunnage and Handling Trays in the industrial equipment Industry

2026-10-02 Plastic News 0 views

Industrial equipment buyers increasingly specify industrial dunnage and handling trays instead of injection moulding or corrugated board. Here is where they are used and why they work.

Everything here can be checked on a real sample before you commit to a production order.

Product Overview

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; stack and nest geometry; returnable and reusable designs. Materials most often specified are Polyethylene Terephthalate, High Density Polyethylene, Acrylonitrile Butadiene Styrene, Polycarbonate, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.

In the industrial equipment sector the decision is usually driven by thick gauge capability and flare and fire rating, with paintability as a secondary requirement. Typical end uses include equipment covers, twin sheet panels, kiosk shells.

Key Material Properties

These figures are typical for commercial grades and should be confirmed against the supplier's certificate for your specific lot.

MaterialDensityTensile strengthService temperature
Polypropylene0.90-0.91 g/cm³25-40 MPa-10°C to 100°C
High Density Polyethylene0.94-0.97 g/cm³20-32 MPa-50°C to 80°C
Polyethylene Terephthalate1.35-1.40 g/cm³50-70 MPa-40°C to 70°C

Polypropylene is frequently the default selection here: PP is the lightest mainstream packaging resin and keeps its shape under repeated flexing.

Where Industrial dunnage and handling trays Is Used in industrial equipment

The list below covers both high volume and specialised uses.

  • protective guards – thick gauge capability
  • equipment covers – paintability
  • machine housings – thick gauge capability
  • twin sheet panels – dimensional stability
  • kiosk shells – flare and fire rating

Common Grades and Variants

  • Acrylonitrile Butadiene Styrene based: high impact toughness
  • High Density Polyethylene based: high impact strength even at low temperature
  • Polypropylene based: lowest density among commodity plastics
  • Polyethylene Terephthalate based: excellent barrier to CO2 and moisture

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.

Processing and Finishing Options

The route below is the one most factories use for this type of part.

  • Twin sheet forming
  • Cnc trimming
  • Assembly
  • Thick gauge thermoforming

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.

How to Specify Industrial dunnage and handling trays Correctly

Use this checklist when comparing two or three supplier quotations.

  1. validate washing and drying resistance
  2. design locating features that survive repeated use
  3. define the number of returnable trips expected
  4. check stack load and conveyor compatibility
  5. specify ESD grade if electronics are handled

Send this list to your supplier with the drawing and you will receive comparable quotations from every factory you contact.

Frequently Asked Questions

Which certifications can you provide?

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.

What is the minimum order quantity for industrial dunnage and handling trays?

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.

What tolerance can be achieved?

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.

How do you control colour consistency?

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.

Can you produce industrial dunnage and handling trays in Polypropylene?

Yes. {mat1} is one of our regular materials for this item, and we can supply virgin, modified and certified grades with full traceability. Material certificates and test reports are issued per batch.

Conclusion

If you are planning a new industrial equipment project, send us your drawing, annual volume and target properties, and we will come back with a material proposal, a tooling plan and a budget quotation.
