High Density Polyethylene (HDPE) and Polypropylene (PP) are the two most quoted options for recycled plastic products and compounds in retail and display projects. Both are widely available, but they behave very differently once they are in service.
Use it as a working checklist when you write your next enquiry.
This category covers a family of products rather than a single item. In practice a buyer defines recycled plastic products and compounds 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 food contact and non-food grades; glass filled reinforced compounds; pellet, flake and finished part forms. Materials most often specified are Polystyrene, Recycled PET, Polylactic Acid, Polypropylene, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the retail and display sector the decision is usually driven by optical clarity and printability, with scratch resistance as a secondary requirement. Typical end uses include light boxes, shelving trays, mannequins.
The table below summarises the values that usually decide the material choice.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Polylactic Acid | 1.24 g/cm³ | 50-60 MPa | up to 55°C (HDT) |
| Polystyrene | 1.04-1.06 g/cm³ | 30-50 MPa | -20°C to 70°C |
| Recycled PET | 1.35-1.40 g/cm³ | 45-65 MPa | -40°C to 70°C |
High Density Polyethylene is frequently the default selection here: HDPE combines toughness with chemical inertness, which is why it dominates pipe and tank markets.
High Density Polyethylene grades offer high impact strength even at low temperature, while Polypropylene brings lowest density among commodity plastics. For retail and display service the difference shows up in chemical resistance and in the long term behaviour under load.
The practical decision usually comes down to the service environment: temperature, chemical exposure and expected lifetime.
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.

Yes. Standard samples are normally free of charge and shipped within three working days; custom samples are charged at cost and credited against the first production order.
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.
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.
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.
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.
Share your specification and quantity with us and we will recommend the most cost effective material, tooling route and packing method for your market.
