Ton bags are also called ton bags and container bags by the people. Because their load capacity is usually measured by tons, they are often called ton bags. At present, the container bags contain various specifications of 0.5-3 tons, with a volume of 500 Between -2300L, the insurance factor can be designed according to user needs 3:1, 5:1, 6:1. It is convenient to ship bulk powdery materials, and has the characteristics of large volume, light weight, and easy loading and unloading. It is one of the common packaging materials.
The structure is simple, the weight is light, it can be folded, the space occupied by the back space is small, and the price is low. Big bag is a kind of flexible transport packaging container. It has the advantages of moisture-proof, dust-proof, radiation-resistant and firm, and has sufficient strength in structure. Due to the convenience of loading and unloading and handling of container bags, the loading and unloading efficiency has been significantly improved, and it has developed rapidly in recent years. Ton bags, container bags, and soft trays are made of polypropylene as the main raw material. After adding a small amount of stable seasonings and mixing them evenly, the plastic film is melted and extruded through the extruder, cut into filaments, and then stretched. It is shaped into high-strength and low-elongation PP raw silk, and then woven and coated to make a base fabric of plastic woven cloth, which is sewn with slings and other accessories to make a ton bag. Container bags are divided into three types according to the shape: round, square and U-shaped. The lifting structure has top hanging type, side hanging type and bottom hanging type, usually with inlet and outlet. It can be widely used in the packaging of various powdery, granular and massive items such as chemicals, building materials, plastics, mineral products, etc. It is an ideal product for storage, transportation and other industries.
When the sling of the big bag is connected to the bag body, there are various forms such as top hanging, bottom hanging, side hanging, etc., and are connected by sutures, so the sutures are also very important. Only relying on the high strength of the sling, the base fabric and stitches cannot reach a certain strength, nor can it ensure the overall high performance of the container bag. For a container bag that can achieve a coefficient of more than 5 times, two of the four lifting rings or one of the two lifting rings must have a tensile performance of more than two and a half times the rated load. Overall there will be no problem. The products of container bag manufacturers are mostly used for hoisting. The quality of its slings and seams is very important during hoisting. Manufacturers want to ensure the quality of their products. In the actual production and processing process, the amount of filler masterbatch needs to be strictly controlled, generally around 2%. If the masterbatch is added too much, it will also have a certain impact on the quality. Generally, when each batch of products is produced, a lifting test will be carried out on them, and only products that pass the test can be mass-produced and shipped.
