my country's plastic woven container bags are mainly exported to Japan and South Korea, and are vigorously developing 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 use
Mainly develop plastic woven products, and the demand for FIBC is also great. Africa can accept the quality and grade of China's FIBC, so there is no big problem in opening the market in Africa. The United States and Europe have very high requirements for the quality of FIBCs, and China's FIBCs still cannot meet their requirements.
The quality of the FIBC is very important. Therefore, the international market has its own strict standards for FIBC products. The focus of the standard varies. Japan pays attention to details, Australia pays attention to form, and the European Community standards pay attention to product performance and technical indicators, which are brief and concise. The United States and Europe have strict requirements on the anti-ultraviolet, anti-aging, safety factor and other aspects of FIBC.
The quality of my country's FIBC still cannot meet the European standards EN1898-2000 and EN277-1995, the European FIBC Association EFIBCA standard, the British packaging standard BS6382, and the Australian standard AS3668-1989. It needs to be developed at a high level.
The 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 is filled with several times the contents and repeatedly raised, whether there is any abnormality in 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. The five-fold safety factor of FIBC products can be used safely for longer. It is an indisputable fact that if the anti-ultraviolet additives are added, the FIBC will have a wider application range and stronger competitiveness.
When the sling is connected with the bag body, there are various forms of top hanging, bottom hanging, side hanging, etc., and they are connected by sutures, so the sutures are also very important. With the high strength of the sling alone, the base fabric and suture cannot reach a certain strength, and the overall high performance of the container bag cannot be ensured.
The bulk bag is mainly packed with block, granular or powdery items, and the physical density and looseness of the contents have obvious different effects on the overall result. As for the basis for judging the performance of the FIBC, it is necessary to test as close as possible to the product that the customer wants to load. This is the "standard filler for testing" written in the standard. As far as possible, the technical standards should be used to meet the challenges of the market economy. .
Generally speaking, there is no problem with the FIBC that passes the lifting test. If the bags really fall off when they are hoisted in ports, railways, and trucks, there are only two cases: one is the operation error, and the other is that this type of FIBC fails the lifting test.
For a container bag that can achieve a safety factor of more than 5 times, two of the four rings or one of the two rings must have a tensile performance of more than two and a half times the rated load, even if the two slings are disconnected, the container bag There will be no problem overall.
Container bag products have a wide range of applications, especially for the packaging of bulk cement, grain, chemical raw materials, feed, starch, minerals and other powder and granular objects, and even dangerous goods such as calcium carbide. It is very convenient for loading and unloading, transportation and storage. . FIBC products are in the rising stage of development, especially the one-ton, pallet form (one pallet holds one FIBC, or four) FIBCs are more popular.
The standardization of the domestic packaging industry lags behind the development of the packaging industry. The formulation of some standards is inconsistent with the actual production, and the content is still at the level of more than ten years ago. For example, the FIBC standard is formulated by the transportation department, the "Cement Bag" standard is formulated by the building materials department, the "Geotextile" standard is formulated by the textile department, the "woven bag" standard is formulated by the plastics department, and so on. Due to the lack of pertinence of product use and full consideration of the interests of industries, there is still no unified, effective and balanced standard.
Calcium carbide is a dangerous substance that is flammable and explosive when exposed to temperature, and it has high requirements for packaging. There is a container bag made of multilayer composite materials, which can pack dangerous goods such as calcium carbide. The capacity is one ton. The bag body is composed of outer, middle and inner three layers. The outer bag is made of laminated plastic woven, the inner bag is made of polyethylene film, and there are four to five layers of special composite materials suitable for packaging such as calcium carbide. This kind of container bag has better sealing performance, higher strength and lower cost. Compared with traditional iron drum packaging, it reduces the transportation cost by more than 10%, and the loss of powder is only one-tenth, which is economical. Greatly improve.
The use of FIBCs in my country is expanding, and the export of FIBCs for special purposes such as calcium carbide and minerals is also increasing. Therefore, the market demand potential of FIBC products is great, and the development prospects are very broad.
