The production of ton bags is a meticulous process, requiring multiple steps. First, high-quality raw materials, such as polypropylene, are selected and melted, extruded, and drawn into a high-strength woven fabric. The fabric is then cut to the desired size and joined together through sewing or heat-seal techniques to create the basic shape of the ton bag. Finally, lifting rings are installed at the four corners to facilitate loading and unloading.
Strict quality control is required at every step of the production process to ensure the strength and durability of the ton bag. For example, when sewing, the stitches must be even and secure to prevent unraveling or breakage. When installing the lifting rings, they must be positioned accurately and securely to withstand significant tensile forces.
