[0002] Container bags, also known as ton bags or space bags, are large bags used for packaging, handling and transporting goods. They have the characteristics of large volume, light weight, and easy loading and unloading. They are usually made of strong materials such as polypropylene and polyester. Container bags are widely used in the transportation and packaging of powdered, granular and blocky items such as food, grains, medicines, chemicals, and mineral products. Container bags are made of polypropylene as the main raw material, with a small amount of stabilizing seasoning added and evenly mixed. The plastic film is melted and extruded by an extruder, cut into filaments, and then stretched. The PP raw filaments with high strength and low elongation are made by heat setting. The base fabric is then woven and laminated to form a plastic woven cloth, which is then sewn with accessories such as slings to form a ton bag.
