A sample is not a formality — it is the cheapest place to find out that a spout does not fit your filling chute or that a loop height is wrong for your forklift. This page sets out how samples run from specification to bulk approval.
When a sample is worth doing
- A new filling line, hopper or discharge arrangement you have not packed before.
- A material that is unusually fine, unusually heavy, or prone to hardening in the bag.
- A first order with a new supplier, where you need to see the construction before committing.
The sample sequence
- Specification confirmed — dimensions, load rating, fabric, inlets and outlets, lifting configuration.
- Sample production — 1–2 bags built to that specification.
- Dispatch — usually by FedEx or UPS, within 7–10 days.
- Your test — fill, lift, move and discharge the bag on your own equipment.
- Feedback and adjustment — changes agreed and, where needed, a revised sample issued.
- Bulk approval — the approved sample becomes the reference for the production run.
Sample cost
For standard dimensions, sample bags are provided free and you cover the courier cost. Where a size is unusual or a fabric has to be woven specially, a sample charge applies; we tell you before making it rather than after.
What we need from you to start
The product you pack, its bulk density, the target load, your filling and discharge method, and where the samples should be sent.
