A poly bag factory cannot prepare a reliable written quote from a short message such as “please quote PE bags.” The quote depends on material, finished dimensions, thickness basis, quantity, artwork, packing, destination and the commercial term.
What product details should be included first?
Start with the bag construction and use case. A factory needs to know whether you need flat bags, gusset bags, zip lock bags, self-adhesive bags or film rolls.
Basic product information
- Bag or roll type.
- Product packed inside the bag.
- Expected product weight and any sharp edges.
- Retail display, warehouse packing, e-commerce inner packing or industrial use.
How should material and thickness be described?
Material and thickness drive both performance and cost. If the material is uncertain, compare LDPE, HDPE and LLDPE before finalizing the RFQ.
| RFQ Item | What to Send | Why It Matters |
|---|---|---|
| Material | LDPE, HDPE, LLDPE, recycled-content request or “need recommendation” | Affects clarity, stiffness, tear resistance, sealing and document review |
| Thickness | Micron, mm or mil, plus whether it means per wall or total thickness | Prevents quotes based on different measurement assumptions |
| Tolerance | Required plus/minus range or receiving inspection standard | Defines acceptance criteria before production |
What dimensions should be sent?
Send finished bag dimensions, not only product dimensions. If you have a current sample, measure it and attach photos. Use the custom poly bag measurement guide if the bag includes zipper, flap, header, hang hole or gusset details.
Dimension checklist
- Finished width and height.
- Gusset depth, if any.
- Zipper, flap, header or hang hole position.
- Usable product space if different from total outer size.
What printing and artwork information is needed?
For printed bags, send artwork before asking for a final printing quote. The factory needs print faces, colour count, print area, coverage, barcode or warning text requirements and editable artwork files when available.
Printing feasibility is reviewed after artwork is checked. Flexographic or gravure printing should be selected against artwork, order plan and acceptance requirements, not only against a generic unit price.
What commercial and packing details affect the quote?
Quantity, packing and delivery terms change the written quote. Ask for quantity scenarios only when the material, size, thickness and printing are the same.
- Quantity by size and design.
- Pieces per inner pack and carton.
- Carton marking, label or pallet requirements.
- Destination country, port or delivery address.
- Requested Incoterm, such as EXW, FOB, CIF or DDP request for review.
Should sample requirements be included?
Yes. State whether you need a material sample, existing reference sample, printed proof, pre-production sample or finished-bag sample. Samples are charged at cost and the sample charge is credited against the first production order.
FAQ
Can a factory quote from photos only?
Photos help the feasibility review, but they are not enough for a reliable final quote. The factory still needs dimensions, thickness basis, material, quantity, packing and destination details.
Should I ask for several quantities in one RFQ?
Yes, if the specification is identical for every quantity scenario. Do not compare prices across different materials, thicknesses, printing coverage or packing methods.
What if I do not know the best material or thickness?
Write “need recommendation” and provide product size, weight, photos, use case and handling conditions. The factory can then review material and thickness options against the actual packaging requirement.
