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.
