International standard ton bag pattern Ton bag (also known as container bag/space bag /1 flexible container/ton bag/ton bag, space bag / bag): is a flexible transport packaging container. It has the advantages of moisture-proof, dust-proof, radiation resistance, firm safety, and has sufficient strength in structure. Because the loading and unloading of container bags are very convenient, the loading and unloading efficiency has been significantly improved, and it has developed rapidly in recent years. Container bags are made of polyester fibers such as polypropylene and polyethylene.
Ton bags, also known as flexible container bags (fexible freightbags), container bags, space bags, etc., is a medium-sized bulk container, is a kind of container unit equipment, with a crane or forklift can achieve the container unit transportation.
It is easy to ship bulk powder materials, has the characteristics of large volume, light weight, easy loading and unloading, etc., is one of the common packaging materials. It is characterized by simple structure, light weight, folding, small space occupied by return, and low price.

Development course
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 in this paragraph, the Middle East has a great demand for container bag products: in Africa, almost all of its state-owned oil enterprises are mainly to develop plastic woven products, and the demand for container bags is also great. 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 hanging, bottom hanging, side hanging, and so on, and they are connected by 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 have passed 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, 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.
Container bag products are widely used, especially the packaging of bulk cement, grain, chemical raw materials, feed, starch, minerals and other powder, granular objects, and even dangerous goods such as calcium carbide, loading and unloading, transportation, storage, are very convenient. Container bag products are in the rising stage of development, especially in the form of one-ton loading and pallet (a pallet in a container bag, or four ) container bag, 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 of products, and the content is still at the level of more than ten years ago. For example, the "container bag" 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 plastic department, and so on. Due to the lack of the pertinence of product use and the full consideration of the interests of the industry, there is not a unified, effective, and balanced interest standard.
Calcium carbide is a kind of inflammable and explosive dangerous goods in case of temperature, which has high requirements for packaging. There is a container made of multilayer composite material, which can pack dangerous goods such as calcium carbide. The capacity is tons, the bag body is composed of outer, middle and inner three layers, the outer bag is laminated plastic woven, the inner bag is polyethylene film, and the middle is composed of four to five layers 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 the traditional iron drum packaging, reduces the transportation cost by more than 10%, the powder loss is only one-tenth, and the economic efficiency is greatly improved.
The scope of use of container bags in China is expanding, and the export of special purpose container bags such as calcium carbide and mineral items is also increasing. Therefore, the market demand potential of container bag products is very broad development prospects.
The design of container bags in this section should strictly implement the GB/T10454-2000 national standard. Container bags as export packaging, to ensure that the export goods in the loading and unloading, transportation and storage process to effectively protect the loaded goods, fully intact goods shipped to the destination. Therefore, the design of container bags must meet the four main points, that is, safety, storage, usability, sealing.
Step 1: Security
Mainly refers to the strength of container bags. In the design, we should consider the packaging volume, the weight of the load and the number of packaging units, but also consider the distance of transportation and the number of handling times, which means of transport and transportation methods. In the GB/T10454-2000 national standard for container bags, the technical index requirements of container bag base cloth and sling are strictly stipulated, and from the safety point of view, it is clear that the container bag structure is all bottom lifting structure. The safety factor must be 1.8.
2. Custodianship
Should be based on the user's conditions of use, reasonable selection of materials, reasonable ratio. The anti-aging ability of plastic products under sunlight exposure is a problem of concern, and it is also a problem often encountered in the actual use of container bags. Pay attention to the use of anti-violet agents and the selection of materials in the production process.
3. Usability
When designing container bags, it is necessary to fully consider the specific ways and methods of customers using container bags, such as lifting, transportation mode, loading material performance, etc. In addition, we should also consider whether it is food packaging, and consider that the food is non-toxic and harmless.
4. Tightness
Different packaging materials have different sealing requirements. Such as powder or toxic items, afraid of contamination of the items on the sealing performance is very strict, easy to damp or mildew materials also have special requirements for air tightness. Therefore, when designing container bags, pay attention to the effect of substrate coating process and sewing process on sealing.
