A square-bottom bag, as the name suggests, is a bag with a square-shaped bottom. Its key features are its ability to stably hold heavier items and its well-thought-out, easy-to-store design. Because square-bottom bags significantly enhance space utilization and operational efficiency, they are extremely common in everyday life. The design principle centers on the stability provided by the square base: compared with traditional round-bottom bags, square-bottom bags offer a more solid foundation that resists tipping over. At the same time, they make full use of the three-dimensional space available for items, saving storage space without compromising the quality of the contents. In addition, these bags have a wide range of applications.

Square-bottom valve bags offer excellent sealing performance. In contrast, conventional packaging bags typically have their bottoms and seals sewn shut with sewing-machine thread, which can repeatedly puncture numerous holes on the left side of the woven fabric at the seam area. Since the sewing thread does not securely grip these holes, leakage is prone to occur.
