Products Descriptions
As a bag closing machine heads and integrated systems manufacturer, we develop the GK35-8A 2-needle 4-thread automatic bag closing machine-an automated upgrade from the GK35-8, engineered for high-speed, leak-proof packaging in industrial production lines. Designed to deliver robust stitches and seamless automation, this machine is a reliable choice for powder, granular, and bulk-filled bag sealing.
Featuring a 2-needle 4-thread bottom feed chain stitch design, the GK35-8A double needle bag closing machine for jute/PP woven bags creates two parallel chain stitch rows-ensuring exceptional seam firmness to prevent material leakage. Equipped with a pneumatic automatic cutter, it effortlessly trims crepe tape and thread without manual intervention, streamlining the sewing process. Developed for automatic bag sewing systems, this machine enables quick bag mouth stitching and integrates seamlessly with sewing pedestals, bag infeed devices, tag placers, and conveyors to form a complete packaging line.
Versatile in application, the GK35-8A sew all filled bags made of burlap, jute, cotton, paper, plastic, and woven polypropylene materials. It is ideal for packaging powder and granular products across food, chemical, feed, agricultural, and port industries, delivering consistent, efficient performance for high-volume production.
For single-needle options (with or without automatic functionality), explore our GK35-2C (manual) and GK35-6A (automatic) models.

Products FAQ
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.
4. How about the packaging and transportation of that machine?
A: All the machines are packed in standard export cartons or wooden packaging boxes to prevent damage during transportation.
