High-strength, smooth-running threads built for heavy-duty bag closing and bulk packaging operations.
Spun polyester bag closing thread from Mahalaxmi is purpose-built for high-volume industrial packaging applications such as FIBC, woven sacks, feed bags and fertilizer bags. The thread combines very low elongation with high modulus to deliver clean and consistent seams that withstand heavy load, rough handling and exposure during transport and storage.
Made from 100% continuous filament polyester with a spun surface, these threads provide excellent stitch formation even on coarse and abrasive fabrics. The micro-lubrication ensures smooth running through high-speed bag stitching machines, reducing breakage and friction and ultimately improving productivity and machine life.
With excellent resistance to ultraviolet rays, stain-free performance and colorfastness, the thread maintains its strength and seam integrity in storage yards, warehouses and open environments. It is available in multiple deniers and cone/reel formats to match customer requirements for FIBC stitching, bag mouth closing, bag hemming and reinforced seams.
| Tkt | Tex No. | Construction (Ply/Ne) | Breaking Strength (Kg) | Elongation Range (%) | Recommended Needles (NM) |
| 180 | 16 | 150*1 | 0.60 | 20 – 34 | 70 – 80 |
| 110 | 24 | 198*1 | 0.90 | 25 – 30 | 80 – 90 |
| 90 | 35 | 300*1 | 1.20 | 20 – 34 | 90 – 110 |
| 50 | 50 | 150*3 | 1.80 | 25 – 30 | 80 – 110 |
| 35 | 60 | 150*4 | 2.40 | 25 – 30 | 110 – 130 |
The high modulus structure ensures tight, uniform stitching with minimal seam distortion, even on high-tension bag closing machines.
Ensures durability of seams during transportation and outdoor storage, protecting the integrity of feed bags, FIBCs and fertilizer sacks even under prolonged sun exposure.
Micro-molecular lubrication helps the thread glide through guide eyes, needles and existing stitch lines with minimal wear on machine parts — allowing long, continuous production runs.
Designed to handle coarse woven polypropylene, jute and geo-textile fabrics without fluffing, fuzzing or breaking, delivering reliable seam strength in high-friction environments.
Available in multiple ticket sizes and spool formats to suit different bag-closing and overedge machines, including reels for automated systems and cone formats for conventional sewing heads.
Resists fading and dye bleeding when in contact with contents or exposed to moisture, maintaining a clean, professional look on end products.
