Ton bag manufacturer my country's plastic woven bulk bags are mainly exported to Japan and South Korea, and are vigorously developing the markets in the Middle East, Africa, the United States and Europe. Due to the production of oil and cement, the Middle East has a great demand for bulk bag products; in Africa, almost all of its state-owned oil companies focus on the development of plastic woven products, and the demand for bulk bags is also great. Africa can accept the quality and grade of China's bulk bags, so there is no big problem in opening up the market in Africa. The United States and Europe have very high requirements for the quality of bulk bags, and China's bulk bags cannot meet their requirements. The quality of bulk bags is very important. Therefore, the international market has its own strict standards for bulk bag products. The focus of the standards is different. Japan pays attention to details, Australia pays attention to form, and the EC standards pay attention to product performance technical indicators, which are concise and concise. The United States and Europe have strict requirements for bulk bags in terms of UV resistance, aging resistance, safety factor, etc. "Safety factor" is the ratio between the maximum bearing capacity of the product and the rated design load. The main thing to look at is whether there are any abnormalities between the contents and the bag body, and whether the connection is damaged when the container bag is loaded with several times the contents and repeatedly lifted. In similar standards at home and abroad, the safety factor is generally set at 5-6 times. Container bags 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 many 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 sutures 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, it is necessary to use products as close to the customer's load as possible for testing. 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 bulk bags that pass the lifting test. If the bag really falls down during lifting at ports, railways, or trucks, there are only two situations: one is that the operation is wrong, and the other is that the bulk bag fails the lifting test. For any bulk 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 lifting straps are disconnected, there will be no problem with the bulk bag as a whole.
