Jumbo bags are made of polypropylene as the main raw material. After adding a small number of stable condiments, the plastic film is melted and extruded by an extruder, cut into filaments, and then stretched, and then heat-set into high strength and low elongation. The PP raw yarn is woven and coated to make the base fabric of the plastic woven fabric, which is stitched with suspenders and other accessories to make jumbo bags.
