FIBC printing and labeling should be treated as controlled technical information, not as a final cosmetic step. Logos matter, but industrial bulk bags also carry handling instructions, Safe Working Load, safety factor, product identification, batch information and customer-specific markings. One wrong number, outdated artwork file or misplaced label can create confusion long after the bag leaves the factory.

For buyers, the safest approach is to approve artwork and technical markings against the same current FIBC specification. Printing approval should never exist as a disconnected email thread while the bag drawing, liner, dimensions or load rating continue to change.

FIBC Printing and Labeling: Why It Is Part of the Specification

An FIBC is an engineered transport package. The information printed or attached to it tells operators what the bag is, how it should be handled and which production lot it belongs to. That information can affect safety, traceability and receiving checks.

ISO 21898:2024 includes marking requirements for FIBCs intended for non-dangerous goods. The practical lesson for procurement teams is that technical data on the bag should come from approved records, not from memory or an old artwork file.

1. Lock the Correct Artwork Revision

The first approval check is revision control. Buyers should provide one clearly identified artwork file and ensure the supplier knows which version is final. File names such as “final2,” “latest-new” and “use-this-one” are poor controls when multiple people are involved.

A stronger process uses an artwork number or revision code that is referenced on the purchase order or approved specification. If text, dimensions or bag construction changes after artwork approval, confirm whether the artwork must be reviewed again.

2. Separate Brand Artwork From Technical Markings

Branding and technical information serve different purposes. A logo can often be moved or resized without affecting safety, while SWL, safety factor or handling text must remain accurate and readable.

Buyers should therefore define separate information layers:

• company logo and marketing text;
• product identification;
• SWL and safety factor;
• handling or storage instructions;
• customer item code;
• batch or traceability fields;
• barcode or QR information where required.

Keeping these layers separate makes change control easier.

3. Verify SWL and Safety Factor Against the Approved Bag

Never approve printed load information before confirming the tested design. If the bag specification changes, the printed rating must still match the approved FIBC.

Our FIBC safety factor guide explains why SWL and safety factor are not interchangeable. The printed values should be copied from controlled technical documents, not assumed from a previous order.

4. Confirm the Number of Print Faces and Orientation

A statement such as “2-side print” can still create ambiguity. Which two panels? How should the artwork appear when the bag is filled? Should the logo face the forklift aisle, pallet opening or customer display side?

Buyers should approve:

• exact print faces;
• artwork orientation;
• distance from seams and edges;
• print size;
• number of colors;
• special language or customer requirements.

This is particularly important on U-panel, four-panel and baffle FIBCs because panel construction affects the visible surface.

5. Check Ink and Surface Compatibility

Print appearance depends on woven fabric texture, coating, ink and the printing process. Coated fabric can offer a smoother print surface, while uncoated woven polypropylene may produce a different finish.

If print clarity matters, include it during fabric selection rather than discovering the issue after production. Our coated vs uncoated FIBC guide explains why coating affects more than moisture behavior.

6. Control the Main FIBC Label

Many FIBCs use a sewn or attached label carrying standardized product and handling information. Buyers should verify that the label is readable, durable enough for the expected logistics cycle and attached in a location that remains accessible after filling.

The label content should match the current bag specification. Typical controlled fields may include manufacturer details, bag identification, dimensions, SWL, safety factor, production reference and other application-specific information.

The FIBCA handling guidelines provide general safe-use guidance and reinforce the importance of consulting the supplier for the specific handling environment.

7. Build Traceability Into the Printed Information

Good traceability does not require every production record to be printed on the bag. Instead, the bag should carry enough identification to connect it back to controlled records.

A batch code, order number, production date or barcode can provide that link. The format should be agreed before production so receiving teams know what to capture.

For a deeper review, see our FIBC traceability guide, which covers the records buyers should verify before approval.

8. Verify Barcodes and QR Codes Before Mass Printing

Digital identification can reduce manual data entry, but only if the code works in the real operating environment. A QR code that scans perfectly from a PDF may fail when printed too small on woven fabric or distorted by the filled bag shape.

Before production, test:

• code size;
• contrast;
• quiet zone around the code;
• scanning distance;
• data format;
• whether the code remains visible after filling and palletizing.

For serialized codes, buyers should also confirm how duplicate prevention and data handover will be managed.

9. Approve a Production Proof, Not Only a Screen File

Digital artwork is essential, but it does not always predict the final result on woven polypropylene. Where printing is critical, ask for a production proof, printed fabric sample or first-article confirmation before the full order proceeds.

Check spelling, dimensions, colors, barcode readability, orientation and technical values. A five-minute approval at this stage can prevent thousands of bags from carrying the wrong information.

How Printing Interacts With Bag Construction

Artwork cannot be controlled in isolation from the FIBC design. A seam may run through a planned print area. A baffle or panel change can alter visible width. A document pouch may cover text. A label position may interfere with a lifting loop or discharge arrangement.

That is why artwork approval should reference the same current bag drawing used for manufacturing. If you are still defining the bag, use our FIBC selection guide and FIBC RFQ checklist before locking print.

Common FIBC Printing and Labeling Errors

Old customer artwork is reused

The visual design may look identical while product code, address, SWL or warning text has changed. Every repeat order should confirm the current revision.

Technical values are typed manually

When the artwork team retypes numbers instead of copying controlled data, transcription errors become more likely.

Too much information is crowded onto one panel

Industrial markings need readability. A smaller font is not always the right solution. Separate branding, technical information and traceability logically.

Barcode testing happens after production

Scanning performance should be validated before the print run, especially on textured woven fabric.

Artwork approval is not linked to the purchase order

Without a clear reference, the factory can receive conflicting files from different people. One controlled approval source is safer.

Buyer Artwork Approval Checklist

• Correct customer and product name
• Current artwork revision
• Correct bag drawing or specification reference
• SWL and safety factor verified
• Print faces and orientation confirmed
• Colors and print size confirmed
• Required warning or handling text checked
• Batch or traceability fields defined
• Barcode or QR code tested
• Label and document-pouch position approved
• Final proof signed off before production

What This Means for FIBC Manufacturers in India

For FIBC manufacturers in India supplying international buyers, artwork control is part of export quality. The factory should connect approved artwork to the correct item code, specification and production order so operators are not relying on informal instructions.

Strong suppliers also make changes visible. If a customer requests a different SWL, panel design, warning statement or barcode, the artwork should move through a controlled revision process before production resumes.

Frequently Asked Questions

What information is normally printed on an FIBC?

It may include branding, product identification, handling instructions, SWL, safety factor and customer-specific information. The exact marking requirement depends on the bag and application.

Should SWL be printed on the FIBC?

Load-rating information should match the approved and tested bag specification. Buyers should verify the exact marking requirement for their application.

Can QR codes be printed on woven polypropylene?

Yes, but scan performance depends on print quality, code size, contrast and surface texture. A physical test before mass production is recommended.

Does coated fabric print better?

A coated surface can be smoother and may improve print clarity, but final quality also depends on ink, process and artwork design.

Why is artwork revision control important?

It prevents an old logo, product code, warning or technical value from being used on a new production order.

Final Buyer Takeaway

FIBC printing and labeling should be approved with the same discipline as fabric, seams, loops and liners. Link every artwork revision to the correct bag specification, verify technical values and test machine-readable codes before production.
