The development of ton bags

Ton bag, also known as flexible container bag or space bag, is a kind of medium-sized bulk container, mainly by crane or forklift can achieve the unit transportation, it is easy to load bulk powder materials, with large volume, light weight, easy to load and unload characteristics, is one of the common packaging materials.
* The development of ton bags *
In the 1940s, the first form of container bags had been produced; From the 1940s to the early 1960s, container bags were made of PVC rubber for the transport of carbon black rubber products; Later improvements led to the early modern bulk bags, which used polypropylene bags and modern weaving techniques to provide a durable, flexible way to pack and transport materials.
The rapid growth of the container industry occurred during the oil crisis of the mid-1970s, when large quantities of cement were sent to the Middle East, driven by the expansion of refining infrastructure in oil-producing countries. According to statistics, about 30,000 to 50,000 tons of cement are exported from Northern Europe, Spain and Italy by container bag packaging every week.
By the 1990s, a standardized method of transporting goods by container bags had become apparent. Any material that requires flexible containers, or an industry that wants to save storage warehouse space, can be used with container bags for better performance and compact resource management.
Compared with the developed countries, the development of China's container bag industry began in the 1980s, later than the developed countries, but after the rapid development of the past 20 years, the current capacity of China's container bags has been in the forefront of the world.
* International standard for ton bags *
China's container bag standard is GB/T10454-2000, which is modified on the old standard GB/T 10454-1989, China's container bag standard specifies the classification structure of the container bag, technical requirements and inspection requirements. This standard applies to container bags with a volume of (0.5-2.3) m^3 and a load of (500-3000) kg.
Foreign container bag standards mainly include: British standard bs6382, Australian standard as3668-1989, European standard EN1898-2000, European container bag Association standard EFIBCA standard, Japanese standard jisz1651-1988. The as3668-1989 quality testing standard refers to the bs6382 standard, and the two are similar and have little difference. The contents of EN1898-2000 and EFIBCA standard are similar. The test project of Japanese standard jiszl651-1988 is similar to that of China's container bag standard GB/T10454-2000.
These international quality inspection standards for container bags have made more detailed provisions on the production, design and use of container bags, although the large detection direction is the same, but the performance test requirements of container bags are slightly different.
Containerization is actually an operation method proposed by the logistics industry to simplify logistics operations and reduce logistics costs, its main content is to load, unload and handle materials based on the containerization unit. If you want to carry out unitary containerization, it is necessary to use containerization containers, generally the most commonly used containers and pallets, they correspond to the loading of the vast majority of daily general merchandise and other materials, but for special forms of materials such as powder, granular materials, box containers are generally performed, and loading and unloading is more complicated, more residual after unloading, difficult to deal with; Then is there a packaging container that can be convenient for loading and sealing, convenient for combined transportation, and convenient for follow-up treatment. The answer is obvious, we can use bags to package, but because the demand for containerization is a large number of loading and handling, so the requirements for bags are very high, while different powder and granular materials on humidity, oxidation, light also have requirements, which makes this bag to take into account load-bearing sealing and convenient shipment, container bags from this application.
Due to its large loading volume and weight, and its own light weight can be folded and easy to operate, it is commonly called ton bag, ton bag, etc. Under normal circumstances, ton bag refers to woven ton bag, which can be divided into: Heavy-duty bags, tensile bags, anti-static bags, conductive bags and breathable bags, etc., when used for the packaging of sensitive raw materials such as electrode materials, aluminum film inner bags are also used, generally aluminum-plastic inner bags, and the shape of the inner and outer bags is consistent.
