Bulk Bag Factory FAQ
If you are buying FIBCs from our Qingdao factory, start with material, target load and equipment. The answers below show what you can confirm with a catalog sample, what needs a drawing and what to ask us to include with your quotation.
Before requesting a sample
- Start a clear factory conversationThe first reply is more useful if both the requirement and the evidence need are named. An equipment mismatch and an unclear material declaration lead to different next steps.
- Inputs for your first reviewSend one sentence on the application, a model or drawing, and the first result you need.
Stock construction and custom dimensions
A standard open-top or spout design is a starting point for sample comparison. If dimensions, equipment or closure differ, send the target drawing so we can review changes before quote acceptance.
Can I approve from a stock photo?
Ask for a physical sample when size, lifting geometry or closure compatibility drives the decision.
Start with an existing model when its contents, openings, dimensions and handling arrangement fit. If one differs, add a marked drawing and list which changes affect approval.
Ask which dimensions relate to a stock sample and which are custom.
Catalog examples to review
Use an open-top candidate to agree what the drawing needs to show.
Review the insert dimensions and how the neck and closure fit.
Compare the openings, loop layouts, coated construction and other available options for your job.
Useful information for the first message
Give the contents, target net load, how the bag will be filled and emptied, and the lifting arrangement. Include the order quantity and delivery destination.
FIBC Selection by Material and EquipmentSeparate material and load from machine dimensions, use and shipping. Photos with a scale help show fittings that the product title cannot describe.
Send the current bag label, intended fill weight, equipment details and destination.
Spout and equipment measurements
Provide the mating diameter or profile, usable sleeve reach and nearby clearance. Indicate the top and bottom separately and share a photo or equipment drawing if available.
- Identify the clearance around each sleeveThe sewing team needs more than outside pipe diameter. Note clamp reach, nearby obstructions and how much sleeve must extend after fitting.
- Acceptance recordKeep upper and lower measurements in separate entries on the request.
Evidence for lifting and load ratings
Ask for the documents and markings for the exact construction, including loop arrangement and intended handling conditions. A catalog rating or an image cannot establish compatibility with your lifting setup.
Does one report cover every size?
Check that the report identifies the ordered construction and scope. Discuss any difference with the responsible team before purchase.
| Technical check | Match model, closure, body and loops to the exact label. Then have your responsible team review applicability to the objective before scheduling a trial. |
|---|---|
| For approval | Ask for the exact scope, identifier and applicable test record on each candidate. |
Food-contact or electrostatic requirements
State the intended contents, market and buyer standard. Request documents for the complete configuration, including the liner where relevant. Have your responsible team assess the materials and records.
Name the intended market, precise contents, handling environment and any liner. Without the fitted liner designation the reviewer cannot assess the complete assembly.
Provide explicit buyer requirements and ask which configuration is documented.
Coating or a separate liner
A coating sits on the woven fabric. A fitted liner adds its own geometry and closures. Tell us whether the concern is visible dust leakage, moisture loss or gain, or contact with the packed product.
- Compare the two moisture or dust responsesFabric coating, treated seams and a closed fitted liner address different locations. Describe the observed problem and expect a comparison matched to the point of release or ingress.
- Acceptance recordShow the affected area on a picture and agree which result the sample should improve.
Minimum quantity and lead time
Ask for a quote for the chosen configuration. Quantity and lead time depend on size, material, print, sample approval and order schedule. Include both sample and production quantities.
Can a repeat order use the same lead time?
Confirm the current schedule, material and approval requirements for the new run.
| Technical check | Keep test sample quantity, first production quantity and expected reorders separate. Ask where artwork and drawing approval affect the dates. |
|---|---|
| For approval | Have the quote identify its quantity basis, named milestones and shipping terms. |
Photos or drawings for a repeat order
Use the previous drawing and purchase reference, plus the bag or lot label if available. Mark any changes to the top, base, loops or liner you need before confirming the next run.
- Repeat from an approved revisionSend the order ID or drawing, bag label and list of revisions. Where the earlier file is incomplete, send a retained physical example and annotated photos.
- Acceptance recordAsk for any deviations to be marked before agreeing a replacement.
A trial bag for replacing a current design
A metal recycling buyer gave the diameter, height, four-loop layout and required 1,000 kg load of an existing open-top, flat-base bag. The enquiry also flagged sharp offcuts. Bring these separate requirements into the factory review before choosing a model.
Compare retained and revised builds on the same buyer-approved route. Compare dimensions, operation and label evidence separately so you can see why a candidate passes.
Agree the site trial checks and owner before receiving the sample.
