Stitching Mechanism: Electric bag sewing stitch machines use a stitching mechanism, typically a single-thread chain stitch or a two-thread double chain stitch, to close and seal bags. The stitching process creates a strong and secure closure to prevent product spillage. Speed and Stitch Length Adjustment: Electric bag closers offer variable sewing speeds, allowing operators to adjust the stitching speed according to the bag material and desired closure strength. They also often feature stitch length adjustment, enabling customization of the stitch length for different bag types and applications.
