Agriculture and horticulture buyers increasingly specify plastic nets and meshes instead of metal, wood or glass. Here is where they are used, why they work, and what to watch out for.
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; roll length 50 m to 500 m; mesh 4 mm to 50 mm. Materials most often specified are Polypropylene, High Density Polyethylene, Low Density Polyethylene, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the agriculture and horticulture sector the decision is usually driven by UV stabilisation and tear strength, with chemical resistance to fertilisers as a secondary requirement. Typical end uses include shade nets, mulch film, greenhouse film.
Typical values for a general purpose grade are listed below; filled, stabilised and speciality compounds will differ.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| 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 |
| Low Density Polyethylene | 0.91-0.93 g/cm³ | 8-20 MPa | -50°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.
The list below covers both high volume and specialised uses.
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.
Use this checklist when comparing two or three supplier quotations.
Send this list to your supplier with the drawing and you will receive comparable quotations from every factory you contact.
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.
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.
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. 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.
If you are planning a new agriculture and horticulture 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.
