Logistics and warehousing 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 corona treated surface; single wound and centre folded; custom printed up to 8 colours. Materials most often specified are Polyethylene Terephthalate, Polylactic Acid, Polypropylene, High Density Polyethylene, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the logistics and warehousing sector the decision is usually driven by impact protection and load rating, with stackability as a secondary requirement. Typical end uses include protective dunnage, returnable pallets, strapping.
Typical values for a general purpose grade are listed below; filled, stabilised and speciality compounds will differ.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Low Density Polyethylene | 0.91-0.93 g/cm³ | 8-20 MPa | -50°C to 70°C |
| Polyethylene Terephthalate | 1.35-1.40 g/cm³ | 50-70 MPa | -40°C to 70°C |
| Polypropylene | 0.90-0.91 g/cm³ | 25-40 MPa | -10°C to 100°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 logistics and warehousing users specify this product for the following jobs.
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.
These are the criteria that actually predict whether the part will perform in service.

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.
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.
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.
Our team supplies plastic films and flexible packaging to logistics and warehousing customers worldwide, with samples, material certificates and full inspection reports available before mass production.
