The quality of the container bag is very important. Therefore, the international market has its own strict standards for container bag products. The focus of the standards is different. Japan pays attention to details, Australia pays attention to form, and the EC standard pays attention to product performance technical indicators, which are concise and concise. The United States and Europe have strict requirements for container bags in terms of UV resistance, anti-aging, and safety factor. "Safety factor" is the ratio between the maximum bearing capacity of the product and the rated design load. It mainly depends on whether the container bag is loaded with several times the contents and repeatedly lifted, whether there are abnormal conditions between the contents and the bag body, and whether the connection is damaged. In similar standards at home and abroad, the safety factor is generally set at 5-6 times. Container bag products with a five-fold safety factor can be used safely for a longer time. If anti-ultraviolet additives are added, the container bag has a wider range of applications and stronger competitiveness. This is an indisputable fact. When the sling is connected to the bag body, there are multiple forms such as top hanging, bottom hanging, and side hanging, and they are connected by sutures, so the sutures are also very important. Only relying on the high strength of the sling, the base fabric and the seam cannot reach a certain strength, and the overall high performance of the container bag cannot be ensured. The container bag mainly contains block, granular or powdery items, and the physical density and looseness of the contents also have obvious differences in the overall results. For the basis for judging the performance of the container bag, the product close to the customer's load should be used for testing as much as possible. This is the "standard filler for testing" written in the standard, and the technical standards should be used as much as possible to meet the challenges of the market economy.
Generally speaking, there will be no problems with the container bag that passes the lifting test. If the bag really falls during lifting at the port, railway, or truck, there are only two situations: one is that the operation is wrong, and the other is that the container bag fails to pass the lifting test. For any container bag that can achieve a safety factor 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. Even if the two slings are disconnected, there will be no problem with the container bag as a whole. Container bags are widely used, especially for packaging bulk cement, grain, chemical raw materials, feed, starch, minerals and other powdery and granular objects, and even dangerous goods such as calcium carbide, which are very convenient for loading, unloading, transportation and storage. Container bags are in the rising stage of development, especially one-ton and pallet-shaped (one pallet can hold one container bag or four containers), which are more popular.
