About the Colored bag closing thread

Our Colored Spun Polyester Industrial Bag Closing Thread is engineered to combine robust performance with vibrant, fade-resistant hues—ideal for industries that demand both functionality and visual appeal. Manufactured from 100% high-tenacity spun polyester bright fibers, these threads deliver exceptional strength, abrasion resistance, and color consistency, ensuring secure closures and an eye-catching finish on woven polypropylene, multi-wall paper, and burlap sacks used for agriculture, feed, fertilizer, chemicals, and other bulk commodities.

Applications & Industry Segments

Securing polypropylene, jute, or paper bags of seeds, feed pellets, grains (wheat, rice, corn), and pet food. Color coding simplifies product identification (e.g., green thread for organic feed, red for medicated pellets).

Sealing multi-layer paper or plastic-lined bags of flour, sugar, salt, coffee, and spices. Threads comply with food-safety standards, minimizing contamination risk.

Closing heavy-duty sacks containing fertilizers (N-P-K blends, urea), powdered chemicals (calcium carbonate, gypsum), and mineral compounds. High-visibility colors help with inventory management in warehouses.

Sealing woven bags of cement, plaster, sand, and stone dust. Exceptional abrasion resistance ensures reliable closures, even on coarse-textured substrates.

Sealing bales of fiber, textile waste, or nonwoven products. Bright colors add a professional finish and help differentiate between material grades.

Benefits & Customer Advantages

  • Solid-color threads allow manufacturers to align thread color with branding, making each bag instantly recognizable on retail shelves or in a warehouse.

  • Contrasting or matching threads create a polished look that elevates perceived product quality.

  • Smooth feed and low-friction wax finish reduce machine jams and thread breakage by up to 25 %.

  • Consistent diameter and twist minimize tension fluctuations, helping operators maintain steady production speeds (up to 2,200 SPM).

  • Polyester’s inherent resistance to mold, mildew, and UV degradation keeps sealed bags intact during outdoor storage or transit.

  • Color integrity remains for at least 12 months under direct sunlight, ensuring no need for rework or relabeling.

  • High tensile strength means lighter Tex (e.g., Tex 180 instead of Tex 200) can be used for certain bag weights, lowering material costs without compromising performance.

  • Bulk-packaging options—1,000 m cones or 5,000 m bulk tubes—reduce per-meter price, ideal for high-volume operations.

  • Oeko-Tex® and REACH certifications guarantee thread safety for food and pharmaceutical packaging.

  • RoHS compliance assures absence of lead, cadmium, and other hazardous substances, facilitating global market access.
