These bags are prevalent in packaging various products, including grains, seeds, fertilizers, and construction materials. The stitching machine operates by using threads to sew the open edges of the bags, ensuring that their contents remain securely enclosed. This process not only enhances the durability of the bags but also protects the contents from moisture and dust, making it an essential part of the packaging workflow.
