The quality of container bags is very important. Therefore, the international market has strict regulations on container bag products. Japan pays attention to details, Australia pays attention to methods, and European Community regulations pay attention to product function and technical indicators, which are concise and to the point. The United States and Europe have strict requirements for container bags in terms of UV resistance, anti-aging, and safety factors.
First of all, check 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 connections are damaged. If anti-UV additives are added, the application range of container bags will be wider and they will be more competitive. This is an indisputable fact.
When the sling is connected to the bag body, there are many ways such as top hanging, bottom hanging, side hanging, etc., and they are connected through sutures, so sutures are also very 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 effect. As for the basis for judging the function 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 "test-specific standard filling material" written in the specifications. Try to make the technical specifications meet the needs of the market economy as much as possible. Respond to the challenge.
Container bag products have a wide range of applications, especially for packaging bulk powders and granular objects such as cement, grain, chemical raw materials, feed, starch, minerals, and even dangerous goods such as calcium carbide. They are very convenient for loading, unloading, transportation, and storage. The container bag product is in the rising stage of development, especially the one-ton container bag and the pallet method (a pallet contains one container bag or four containers), which are more popular.
Calcium carbide is a dangerous substance that is flammable and explosive when exposed to temperature and has very high requirements for packaging. There is a container bag made of multi-layer composite materials that can package dangerous goods such as calcium carbide. The capacity is one ton. The bag body is composed of outer, middle and inner 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 in the middle of special composite materials suitable for packaging such as calcium carbide. This kind of container bag has better sealing, higher strength, and lower cost. Compared with traditional iron drum packaging, it reduces the transportation cost and the loss of powder to only one-tenth, and the economic benefits are greatly improved.
The scope of use of container bags in my country is expanding, and the export of container bags for special purposes such as calcium carbide and minerals is also increasing. Therefore, the market demand potential for container bag products is huge and the development prospects are very broad.
