These are the questions our engineering team hears most often when agriculture and horticulture buyers source recycled plastic products and compounds, answered in plain language with the numbers that matter.
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 pellet, flake and finished part forms; custom colour compounding; glass filled reinforced compounds. Materials most often specified are Recycled PET, Polylactic Acid, High Density Polyethylene, Polystyrene, 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 drip irrigation lines, mulch film, greenhouse film.
The table below summarises the values that usually decide the material choice.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Recycled PET | 1.35-1.40 g/cm³ | 45-65 MPa | -40°C to 70°C |
| High Density Polyethylene | 0.94-0.97 g/cm³ | 20-32 MPa | -50°C to 80°C |
| Polypropylene | 0.90-0.91 g/cm³ | 25-40 MPa | -10°C to 100°C |
Recycled PET is frequently the default selection here: Food-grade rPET requires a recognised recycling process plus solid-state polycondensation.
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.
Work through these points in order and most specification mistakes disappear.

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.
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.
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.
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.
