Import Bag Closing Thread 20/6,20/8,/20/9 — Buy in Bulk from Supplier in China

Polysun Company manufactures bag closing thread in ticket sizes 20/6, 20/8 and 20/9, with cone weights from 200 gram retail tubes up to 5 kilogram industrial king spools. The product is produced in Jiangyin, Wuxi, Jiangsu Province, within China's dense Yangtze River Delta textile manufacturing corridor. This thread is engineered for high-speed closure of woven polypropylene, kraft paper and laminated multiwall bags across food, agricultural and construction material sectors. The 20/6, 20/8 and 20/9 designation refers to the metric ticket count and ply construction, with lower second numbers indicating thicker, stronger thread for heavier bag weights.

Material construction for this product category is typically 100% spun polyester or polyester-cotton blend, with continuous filament polyester core-spun variants available for premium applications. The 200 gram cone suits portable hand-held bag closers and low-volume operations, while 2-5 kilogram cones feed automated sewing heads for continuous production. Wuxi region manufacturers typically apply paraffin or microcrystalline wax lubrication to reduce friction in guide eyes and looper mechanisms. Thread evenness, measured by Uster imperfection index, and residual shrinkage after heat setting, determine sewing performance under sustained machine operation.

Buyers include grain processors, flour millers, chemical compounders and building materials packers who require reliable closure at stitching speeds of 2,500-3,500 rpm. The 20/9 thread suits lighter bags and higher stitch density; 20/6 handles cement, mineral and fertiliser bags subject to rough handling. No MOQ, price or lead time is stated in the source data, so buyers must negotiate directly with Polysun Company. Request sample cones for compatibility testing with your specific bag closing machine model before committing to volume.
