Specifications to Confirm
This is a quotation checklist, not a stocked SKU specification. Share your requirements; material, minimum quantity, tolerances and schedule must be confirmed in writing before ordering.
| Parameter | Information needed for your quotation |
|---|---|
| Material & composition | Confirm the material grade, layers and any recycled content for the specific product. Supporting documents are required for environmental claims. |
| Bag dimensions | State usable body width × body length, plus the separate closure flap length. Supply mm or inches (1 inch = 25.4 mm). Identify internal or external dimensions and check fit with a sample. |
| Thickness / basis weight | For film: specify thickness in μm per single wall, or explicitly state a two-wall total. For paper: confirm paper grammage and layer construction separately. No default thickness is assumed. |
| Color & opacity | Provide a color reference, transparency or opacity requirement, and confirm the acceptable appearance on a sample. |
| Closure & construction | Confirm flap length, adhesive or other closure, seam layout, and any return-strip requirements. Suitability depends on your packed product. |
| Printing & artwork | Share artwork, number of colors, print sides and placement. The available printing method, printable area, proof and setup charges are confirmed for the job. |
| Samples, trial orders & bulk MOQ | Stock quantities depend on availability. An individual evaluation sample is not a promise of one-piece custom manufacturing. Sample availability, charges, trial quantities and the custom production MOQ are quoted separately. |
| Sampling & production schedule | Timing is confirmed after specifications, artwork and availability are reviewed. Sample approval, production, dispatch and transit are separate stages; no fixed lead time is stated here. |
| Packing & carton details | Confirm pieces per bundle/carton, carton dimensions, gross weight and pallet requirements before the freight quotation. |
| Shipping, duties & quotation scope | Send the delivery country and postal code. Confirm origin, transport service, shipping charges, taxes and import-duty responsibility in the written quotation. Product, setup, sample and freight charges should be identified separately. |
