A square bottom pouch is an upgraded packaging solution featuring a square base design. Manufactured from high-strength polypropylene (PP) woven fabric, it utilizes ultrasonic heat-sealing technology to create a stable square-bottom structure that ensures superior free-standing capability, improving filling and stacking efficiency by over 40%. The three-dimensional square base design increases loading capacity by 20% while maintaining the moisture-proof and UV-resistant properties of traditional square bottom plastic bags. Particularly suitable for products requiring vertical stacking such as animal feed, grains, and construction materials, these square bottom plastic bags represent an optimal smart packaging solution ideally adapted for automated production lines and modern warehousing/logistics applications. The Block bottom bag design enhances both functionality and efficiency, making it a preferred choice for various industries.
