China's plastic woven container bags are mainly exported to Japan, South Korea, and is vigorously developing the Middle East, Africa, the United States and Europe. Due to the production of oil and cement, the Middle East region has a great demand for container products; In Africa, almost all of its state-owned oil companies are based on the development of plastic woven products, and the demand for container bags is also large. Africa can accept the quality and grade of Chinese container bags, so there is no big problem in opening the market in Africa. The United States and Europe have high quality requirements for container bags, and China's container bags can not meet their requirements.
The quality of container bags is good, bad, is crucial. Therefore, the international market for container bag products have their own strict standards. The emphasis of the standards varies. Japan pays attention to details, Australia pays attention to form, and European Community standards pay attention to product performance technical indicators, concise and to the point. The United States and Europe have strict requirements for container bags in terms of anti-ultraviolet, anti-aging, and safety factor.
The "safety factor" is the ratio between the maximum bearing capacity of the product and the rated design load. It mainly looks at whether the contents of the container bag are loaded with several times, repeatedly lifted, whether the contents and the bag body are abnormal, and whether the connection is damaged. In similar standards at home and abroad, the safety factor is generally set at 5-6 times. Container products with five times the safety factor can be used safely for a longer time. If the anti-ultraviolet additives are increased, the application range of container bags is wider and there is a stronger competitiveness, which is an indisputable fact.
When the sling is connected with the bag body, there are many forms of top lifting, bottom lifting, side lifting and so on, and they are connected through the suture line, so the suture line is also very important. Only by the high strength of the belt, the base cloth and stitches can not reach a certain strength, and can not ensure the overall high performance of the container bag.
The bulk bags mainly contain block, granular or powdered items, and the physical density and looseness of the contents also have a significantly different impact on the overall result. The basis for the determination of the performance of the container bag, as close as possible to the customer to load the product test, this is the standard written in the "test special standard filler", as far as possible to make the technical standards to meet the challenges of the market economy.
Generally speaking, the container bags that pass the lifting test will not cause problems. If in the port, railway, truck lifting, the bag really fell down, there are only two cases: one is the operation is wrong, and the other is that this type of container bag failed to pass the lifting test.
Where can reach more than 5 times the safety factor of the container bag, two of the four rings or one of the two rings must have more than two and a half times the rated load tensile performance, even if the two straps are disconnected, the container bag as a whole will not have a problem.
