If you specify Low Density Polyethylene (LDPE) agricultural plastic products, a handful of properties decide whether the part survives in service. These are the values worth checking on every data sheet.
This guide is written for engineers, purchasers and project managers who need a practical answer, not a resin data sheet.
This category covers a family of products rather than a single item. In practice a buyer defines agricultural plastic products 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 silage and stretch film widths to 750 mm; mulch film 8 to 50 micron; drip line 16 mm with 0.2 L/h emitters. Materials most often specified are Low Density Polyethylene, Polyvinyl Chloride, Polypropylene, Ethylene Vinyl Acetate, 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, signage, point of sale displays.
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 |
|---|---|---|---|
| Polypropylene | 0.90-0.91 g/cm³ | 25-40 MPa | -10°C to 100°C |
| Ethylene Vinyl Acetate | 0.93-0.95 g/cm³ | 10-30 MPa | -40°C to 70°C |
| Polyvinyl Chloride | 1.38-1.45 g/cm³ | 40-55 MPa | -10°C to 60°C |
Low Density Polyethylene is frequently the default selection here: LDPE is the workhorse of flexible packaging because of its softness and sealing behaviour.
Typical values for a general purpose grade are listed below; filled, stabilised and speciality compounds will differ.
Density 0.91-0.93 g/cm³, tensile strength 8-20 MPa, continuous service temperature -50°C to 70°C and melt range 105-115°C are the four values to circle on the data sheet. Everything else is secondary for most retail and display projects.
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.
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.
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.
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.
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.
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.
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.
Our team supplies agricultural plastic products to retail and display customers worldwide, with samples, material certificates and full inspection reports available before mass production.
