The quality of container bags is very important. Therefore, the world market has its own strict standards for container bag products. Canonical side points vary. Japan pays attention to details, Australia pays attention to methods, and European Community specifications pay attention to product function and technical indicators, which are short. The United States and Europe have strict requirements for container bags in terms of UV resistance, anti-aging, and safety factors.
The "factor" is the ratio between the maximum bearing capacity of the product and the additional planned load. It mainly depends on whether the container bag is loaded with several times contents and repeatedly lifted, whether there are any abnormalities in the contents and the bag body and whether the connection is damaged. In similar domestic and foreign standards, the safety factor is generally set to 5-6 times. Container bag products with five times the coefficient can be used longer. If anti-ultraviolet additives are added, container bags can be used in a wider range and become more competitive. This is an indisputable reality.
When the sling is connected to the bag body, there are many methods such as top hanging, bottom hanging, side hanging, etc., and are connected through sutures, so the sutures are also quite important. Just relying on the high strength of the sling, the base fabric and sutures cannot reach a certain strength, nor can the overall high performance of the container bag be ensured.
Container bags mainly contain block, granular, or powdery items, and the physical density and looseness of the contents also have significantly different effects on the overall results. Regarding the basis for judging the performance of container bags, it is necessary to use products that are as close as possible to the products that customers want to load for testing. This is the "standard filling material specifically for testing" written in the standard, and the technical standards should be used as much as possible to meet the needs of the market economy.
