The pp raw silk with elongation rate is spun and coated to make the base fabric of plastic woven cloth, which is sewn with slings and other accessories to make a ton bag.
Performance characteristics: Ton bags are convenient for shipping bulk powdery materials. They have the characteristics of large volume, light weight, and easy loading and unloading.
