Import Bag Closing Sewing Thread — Buy in Bulk from Supplier in China

The Bag Closing Sewing Thread from Tianjin Bonlon Textiles Co., Ltd is produced from high-tenacity, low-shrinkage polyester, available in both staple and filament forms. The thread is twisted and finished using advanced equipment, ensuring consistent performance in industrial sewing applications. It is supplied in a range of specifications, including 8/3, 8/4, 10/3, 10/4, 12/3, and higher counts, as well as heavier deniers like 630D/3, 750D/3, and 1500D/2.

This thread is designed for durability and resistance to breaking under high-speed sewing conditions, a critical requirement for bag closing operations. Low shrinkage ensures the stitches remain tight and secure, even in humid or variable climate conditions typical in storage or transit. The thread is available in natural, dyed, or mixed colours, allowing for customisation to match bag materials or branding requirements. Typical tensile strength for polyester sewing thread in this category ranges from 5-9 grams per denier, with elongation at break around 15-25%.

Primary applications include sewing shut bags made from jute, PP/PE, woven polypropylene, and other packing materials in industries such as agriculture, chemicals, and construction. The thread is sold in make-ups ranging from 200 grams to 8 kg, catering to both small-scale and bulk buyers. Tianjin Bonlon Textiles Co., Ltd does not specify MOQ or lead time, so these should be confirmed directly with the supplier.
