Agriculture and horticulture buyers increasingly specify plastic films and flexible packaging instead of metal, wood or glass. Here is where they are used, why they work, and what to watch out for.
Everything here can be checked on a real sample before you commit to a production order.
This category covers a family of products rather than a single item. In practice a buyer defines plastic films and flexible packaging 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 thickness 12 to 200 micron; corona treated surface; width up to 3000 mm. Materials most often specified are High Density Polyethylene, Polylactic Acid, Polyethylene Terephthalate, 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 mulch film, drip irrigation lines, shade nets.
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 |
|---|---|---|---|
| Polylactic Acid | 1.24 g/cm³ | 50-60 MPa | up to 55°C (HDT) |
| Polyethylene Terephthalate | 1.35-1.40 g/cm³ | 50-70 MPa | -40°C to 70°C |
| Low Density Polyethylene | 0.91-0.93 g/cm³ | 8-20 MPa | -50°C to 70°C |
Low Density Polyethylene is frequently the default selection here: LDPE is the workhorse of flexible packaging because of its softness and sealing behaviour.
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.
Processing method drives both cost and performance, so it should be fixed early in the design.
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.
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.
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.
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.
