Polypropylene (PP) and Low Density Polyethylene (LDPE) are the two most quoted options for plastic nets and meshes in retail and display projects. Both are widely available, but they behave very differently once they are in service.
The notes below come from day to day production and export work with overseas buyers.
This category covers a family of products rather than a single item. In practice a buyer defines plastic nets and meshes 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 weights from 30 g/m²; mesh 4 mm to 50 mm; width 1 m to 6 m. Materials most often specified are High Density Polyethylene, Polypropylene, Low Density Polyethylene, 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 shelving trays, light boxes, mannequins.
These figures are typical for commercial grades and should be confirmed against the supplier's certificate for your specific lot.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Low Density Polyethylene | 0.91-0.93 g/cm³ | 8-20 MPa | -50°C to 70°C |
| Polypropylene | 0.90-0.91 g/cm³ | 25-40 MPa | -10°C to 100°C |
| High Density Polyethylene | 0.94-0.97 g/cm³ | 20-32 MPa | -50°C to 80°C |
Polypropylene is frequently the default selection here: PP is the lightest mainstream packaging resin and keeps its shape under repeated flexing.
Polypropylene grades offer lowest density among commodity plastics, while Low Density Polyethylene brings very flexible and soft. For retail and display service the difference shows up in impact strength and in the long term behaviour under load.
Both materials can be validated quickly with a small sample run, which is the cheapest way to settle the argument for your own application.
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.
Each step below has its own control points, and skipping one of them is where most defects start.
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.

Send this list to your supplier with the drawing and you will receive comparable quotations from every factory you contact.
A new tool typically takes 25 to 45 days depending on cavity count and complexity, followed by T1 samples within one week. Existing tools can usually start production within 10 to 15 days of order confirmation.
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.
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.
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.
