How a Thai Agricultural Bag Manufacturer Scaled PP Woven FIBC Output with a 4-in-1 Conversion Line

Asia-Pacific leads the global FIBC market with over 35% of worldwide volume. The regional market was valued at USD 2.48 billion in 2025 and is forecast to reach USD 3.96 billion by 2033, driven by agricultural commodities, food processing, and chemical export demand. Thailand is a significant FIBC production hub within the region, with manufacturers serving rice, sugar, flour, animal feed, and fertilizer sectors across ASEAN and beyond.

This illustrative case describes a Thailand-based PP woven bag manufacturer supplying FIBC bags to agricultural commodity exporters. The company operated separate printing, tubing, cutting, and sewing stations — a multi-step layout that required significant inter-station handling, created alignment inconsistency, and limited throughput per shift.

Requirements

• Integrate printing, tube forming, cutting, and sewing into one continuous process to eliminate inter-station handling
• Achieve consistent bag dimensions with cutting accuracy ≤ 1 mm
• Add 4-color in-line printing capability without a separate offline print line
• Increase throughput to at least 30 bags/min on standard FIBC formats

Machine Deployed: Reylong JLPTCSM-1300W

The Automatic Printing-Tubing-Cutting-Sewing-Overtape Conversion Line (Model JLPTCSM-1300W) consolidates four production stages into a single continuous line. Specifications relevant to this application:

• Production capacity: 25–40 bags/min
• In-line 4-color flexographic printing (4+0) — print repeat length 450–1,200 mm; max printing width 1,300 mm
• Cutting accuracy: ±1 mm with servo-controlled cutting unit
• Fabric width before tubing: 700–1,300 mm; after tubing: 430–660 mm
• Cutting length range: 550–1,250 mm — covers standard FIBC bottom and body panel formats
• Integrated overtape application at 55 mm or 65 mm width
• Total power: 51.7 kW

Why an integrated line holds dimensional tolerance

In a station-to-station layout, each transfer re-establishes the fabric's reference edge. Every re-grip introduces a small registration error, and those errors accumulate: by the sewing station a panel can sit several millimetres away from the position the printing station assumed. A continuous line removes that compounding effect, because the web keeps one tension and servo reference from unwind through to sewing — the cutting unit measures against the same datum the print unit registered to. That is why consolidation improves dimensional consistency rather than only saving labour, and why the ±1 mm figure holds across a full shift rather than only on a freshly set-up run.

Outcome

• Throughput: 35 bags/min achieved consistently on standard FIBC formats — within the rated range
• Inter-station handling eliminated — fabric moves continuously from print to sew with no manual transfer points
• Cutting accuracy within ±1 mm across the full shift, reducing trim waste and rejected bags from dimensional non-conformance
• 4-color branding added at no additional floor space — the integrated print unit replaced a separate offline printing step

What to check before consolidating a line

Consolidation is a plant decision as much as a machine decision. Three things decide whether it pays off: a continuous floor run long enough for the whole line rather than four separate cells; a 51.7 kW supply delivered at the line instead of distributed across stations; and operator coverage, because one integrated line concentrates responsibility that was previously spread across four crews. Changeover economics shift as well — print repeat and cut length are set once for the entire line, which shortens setup on long runs but makes short, frequent format changes more expensive than they were with independent stations.
