Damaged FIBC bags can be repaired efficiently with an industrial bag sewing machine that is set up for repair and supplementary stitching. The GB6-180-2 is designed for repair-oriented operation, handling seam openings, local stitching failures, bag edge damage, packing bag repair and handle or strap sewing areas at 800 stitches/min with a 0–11 mm stitch length and a 14–20 mm operating room.

Common FIBC Damage

• Seam opening along the bag body or base
• Local stitching failure from overloading or snagging
• Bag edge and corner wear
• Torn handles, straps and lifting loops
• Minor tears in packing bag fabric

Which Damage Can Be Sewn

Repairable damage is generally limited to seam-related and localised fabric faults: opened or loose seams, short stitch runs that have failed, worn edges that can be re-hemmed, and handle or strap areas that can be re-stitched. Damage that compromises the structural integrity of the lifting system, however, cannot simply be sewn over.

GB6-180-2 Features

Repair Procedure

1. Inspect the bag and confirm the damage is repairable.
2. Clean and flatten the damaged area so layers feed evenly.
3. Align the original seam or prepare an overlap patch.
4. Select the correct needle (7×200 to 7×300) for the fabric thickness.
5. Sew with a controlled 0–11 mm stitch at up to 800 stitches/min.
6. Inspect the finished seam and confirm thread tension is even.

When a Bag Should Not Be Repaired

A bag should not be repaired when the lifting loops or webbing are torn, when the base fabric is broadly degraded, when the bag has carried unknown or hazardous chemicals, or when the damage affects the safety factor of the lifting system. In these cases the bag should be taken out of service rather than re-stitched.

FAQ

What is the GB6-180-2 used for?
It is designed for FIBC repair and supplementary sewing, not for continuous production-line bag making.

Can handle and strap areas be repaired?
Yes, handle and strap sewing areas can be re-stitched with the appropriate 7×200–7×300 needle.

How does it differ from the DS9800?
The DS9800 targets continuous FIBC production with up to 14 mm stitches and a large shuttle hook, while the GB6-180-2 targets repair work with a 14–20 mm operating room and 0–11 mm stitch.

Should every damaged bag be repaired?
No. Bags with torn lifting loops, degraded fabric or hazardous contents should be retired, not repaired.
