Our Clients Say
“Our high-speed Newlong closers thrive on the large size of Bag Closing Thread’s robust performance. With 5 kg and 8 kg spool options, boosting our throughput by 30%. The stable yarn tension and abrasion resistance ensure every bags packaging is sealed securely, even at 2,200 SPM. We’ve also seen a marked decrease in machine downtime—maintenance crews now clean guides only once per week instead of daily. This thread has become a cornerstone of our efficiency and quality programs.”
