Read MoreLock stitch is a sewing technique that involves interlocking two threads—one from the needle and the other from the bobbin—to create a strong seam. This method is particularly advantageous for securing the seams of jumbo bags because it provides a tight, secure closure that can withstand significant tension and pressure. Unlike other stitching methods, lock stitch produces a consistent and uniform seam, reducing the likelihood of bag failure due to seam separation.
