Description & Features
Where the U+2 trades a little squareness for economy, the 4-Panel is built for shape. Four flat side panels give a bag that stands as a true cube when filled — no barrelling, no lean. That makes it the natural choice wherever bags are palletised, double-stacked or stored in tight warehouse footprints, and wherever a clean, uniform load matters.
Built in-house from our own tape and yarn, every 4-Panel bag carries consistent GSM and tenacity across all four walls, with double-stitched seams and a full range of loop, liner and discharge options.
- Best-in-class dimensional stability
- Cleaner stacking and palletising
- Even load distribution across four walls
- Better container and warehouse fill
- Food-grade and lined options available
Construction
How the 4-Panel is built.
Four flat woven panels are stitched together to form the four walls, with a separate base. Because each wall is a flat panel, the bag holds a square, upright shape when filled — it doesn't bulge or barrel the way a tubular bag can. That squareness is what makes it stack and palletise cleanly, using container and warehouse space to the full.
Every seam is double-stitched with high-tenacity thread, and hems are reinforced for repeated handling. Generate an enquiry for custom specifications →
