A good enquiry does not have to be long. The most important thing is to describe the application and provide the parameters that actually affect the film execution.
1. Start with the application
The most useful information is the answer to: what will the film be used for? A request for “50 µm PE film” says much less than explaining that the material must protect a large component in transport, line a container or act as an interleave in a production process.
Briefly describe the product, process stage and operating conditions. If you do not know every parameter, that is fine — the application description tells us what needs to be clarified.
2. State the film format
If known, specify flat film, tubing, centre-fold film, bag, sheet, interleave or another format. If you are unsure, describe how the film will be used. In some cases, changing the format can simplify packaging or reduce waste.
3. Dimensions and thickness
Provide width, length or bag dimensions and the expected thickness. For bags, the closing method and how the dimensions are measured may also matter.
If the current film works well, you can send a sample. If it creates problems, describe them: tearing, excessive stiffness, difficult application, insufficient adhesion or other behaviour.
4. Quantity and supply pattern
Give an approximate quantity per order and, if applicable, expected repeat-order frequency. This helps determine a sensible execution and packing method.
For many technical executions, a typical production minimum is around 400 kg. The actual minimum depends on the film type, parameters and complexity. Very short runs may require individual pricing because of set-up, changeover, storage and transport costs.
5. Operating conditions
Temperature, contact time, storage, light exposure, humidity, transport, contact with coated surfaces or process requirements may all be relevant. Not every factor matters in every enquiry — but unusual conditions should be stated.
6. Special requirements
| Area | Useful information |
|---|---|
| PE | format, dimensions, thickness, application, printing, colour, perforation or other special execution |
| EVA | process, temperature, format, dimensions, thickness and how the material enters the process |
| Protective film | surface type and finish, protection time, application/removal conditions and expected adhesion level |
| ESD | type of protected product, packaging method, storage/transport conditions and any defined electrical or standards requirements |
7. A sample, photo or drawing can save time
If possible, send a sample of the material currently used. Photographs, drawings, specifications and process documentation are also useful and can reveal requirements that are difficult to capture in a short description.
If the current solution has a specific weakness, describe it. Selection is not always about copying the existing material — sometimes a deliberate parameter change gives a better result.
