Key Features & Technical Advantages for Your Factory

• Dual Feed System – Unlike standard bag closing machine head, DS-9CU features both upper and bottom feeding structure, ensuring smooth, even stitching on thick woven fabrics, slippery substrates, and heavy-duty materials that often cause feeding issues with regular machines. Perfect for maintaining seal integrity on challenging bags.
• Proven High-Speed Performance – Built on the DS-9C's renowned speed capabilities, the DS-9CU excels in high-volume production environments, delivering efficient throughput to keep your packaging line running at peak performance.
• Full-Sealed Oil Bath Lubrication – Equipped with a fully enclosed oil bath lubrication system and dust-proof needle bearing rollers, this design minimizes wear and tear on moving parts, extends machine lifespan, and reduces maintenance frequency and costs.
• Automatic Guillotine Cutter – Integrated guillotine-type cutter automatically trims thread and crepe tape once sewing is complete, ensuring clean, professional bag finishes every time.

1. What stitch types do PACKSTAR bag closing machines adopt for bag sealing?
A: Our bag closing machines mainly use durable chain stitch, including single-thread, double-thread and four-thread styles. The chain stitch features high tensile strength, not easy to unravel even under heavy load, perfectly suited for long-term stacking and transportation of filled industrial bags.
2. What kinds of packaging bags can PACKSTAR full-series bag closing machines sew?
A: All models adapt to PP woven bags, plastic sacks, paper bags, jute bags and composite lined bags. High-speed and double/four-thread models can handle thickened multi-layer bags, while standard single needle models meet the sealing demands of conventional light and medium packaging bags.
3. How to improve the overall efficiency of the bag closing production line?
A: Match high-speed bag closing machines with synchronous-speed bag infeed devices. Regularly maintain the equipment to reduce downtime. Set reasonable stitch length and running speed according to bag materials to avoid repeated rework caused by unqualified sealing.
