01. Describe what the bag needs to do
Start with the item being packed, how it is handled and where it will be used. Include the destination market and any special documentation your purchasing process requires. A clear application brief helps avoid comparing quotations for different requirements. For a repeat order, identify the specification or reference sample you want to match and explain any changes.
02. Make measurements unambiguous
Provide width and length with units. Show side or bottom gussets separately and explain whether a dimension is measured flat or expanded. A labeled sketch often communicates more clearly than a product name. If you are measuring an existing bag, include photographs of the measurement points and identify the closure or seam arrangement. Ask the supplier to confirm the same measurement convention in the quotation.
03. Include the details beyond size
State your requested thickness, material preference, color, transparency and bag style. Describe any load or testing requirement rather than assuming a material name guarantees performance. For printing, provide artwork, colors and placement. For packing, specify the desired bags per roll or carton, label content and barcode information. Mark details that are still open for discussion.
04. Confirm the sample and commercial terms
Request confirmation of feasibility, MOQ, sample availability, sample cost, production timing and shipping terms. Compare the written specification with the sample and agreed artwork before order approval. If a detail changes, ask for the quotation and approval record to be updated. Final specifications are subject to material, production process, MOQ and manufacturing feasibility confirmation.
