The raw material for manufacturing products is polyethylene and a small amount of stabilizing seasoning needs to be added to it. After sufficient smelting, the plastic film is extruded, cut into filaments, and then stretched to make PP raw material through a heat setting. Silk, after a series of weaving processes, is made into base fabric, and after sewing other accessories, it is made into the big bag we see now.
Therefore, manufacturers are constantly improving heavy-ton bags, which can be cut with scissors. After washing, they can be used to expose things to the sun, and can also be used as dust-proof cloths for some furniture such as sofas. But for those that have been corroded and unusable, they have to be processed to make them degrade faster.
So there are second-hand ton bags, so what should we do with second-hand ton bags?
Generally, most of the occasions we use are on the construction site. In view of this situation, the quantity used on the construction site is relatively large, and a hoist can be used for transportation. Due to the large number and weight of the objects in shape, avoid below or next to them. Standing on people to avoid personal injury, and secondly, the general material of the product is polypropylene, which cannot be installed when in use. It is also possible to carry sharp objects, but secondary use will cause difficulty and increase the cost of use.
Before hoisting, check whether the corresponding sling is broken, which is enough to ensure the safety of hoisting. If conditions permit, ordinary woven bags can be loaded first, and put into container bags before use. When we choose products, we need to choose according to the characteristics of the goods. For example, the specific gravity of the packaged materials determines the volume of the ton bag, and it also depends on whether the loaded materials are sharp and solid block materials. The loss of the strength of the sling during the manufacturing process can be used well, and the hoisting method must also be considered, which requires the sling to meet the weaving density requirements. It is necessary to ensure the strength of the base cloth, and it is necessary to ensure the tensile strength of the flat wire.
