Product Introduction: Container bag full name flexible container bag, also known as big bag, ton packaging bag, is a soft, flexible packaging container, is made of folding adhesive cloth, resin processing cloth and other soft materials made of large volume transport bag. Generally polypropylene or polyethylene as the main raw material, after extrusion film, cutting, wire drawing, and then by weaving, cutting, sewing. This kind of packaging is not only beneficial to improve the loading and unloading efficiency, especially suitable for the packing of bulk powder and granular goods, conducive to promote the normalization and serialization of bulk goods packaging, reduce transportation costs, but also has the advantages of easy packaging, storage and low cost. Especially suitable for mechanized operation, it is the ideal choice for storage, packaging and transportation. It can be widely used for highway, railway and sea transportation of bulk materials such as cement, chemical fertilizer, salt, sugar, chemical raw materials, ore and so on. Therefore, in recent years, all countries in the world have widely used container bags to transport powder and granular goods. The appearance and use of container bags is a qualitative revolution in the way of shipment of powdery and granular goods.

Container bag characteristics: (1) there is enough strength in the structure, loading, unloading operation is convenient, adapt to mechanical loading and unloading, rather than manual operation. Operators use cranes or forklifts to move goods, increasing work efficiency.

(2) The barrier of the raw materials of the container bag is good, the sealing of the structure is also good, and the moisture, debris and dust are not easy to mix, and the protection of the product is good. And light, soft, high strength, acid and alkali corrosion resistance, moistureproof, no leakage, suitable for packing powder, flake, granular solid products, easy to transport and storage.

(3) No packaging, compared with other packaging, container bags generally do not need trays, greatly saving the packaging cost.

④ The container bag can be folded flat, the bale is transported to the end user and folded and placed after unloading, only occupies a very small storage space, and the weight of the container bag used for ordinary 1 T goods is only 3.5 ~ 4.5 kg, therefore, the use of the container bag is more convenient and economic.

⑤ Container bags can generally be customized according to the special needs of the end user, including the size of the bag body and the upper and lower mouth, the style of the sling, the specifications of the base cloth, whether to coat the film, whether to inner bag, etc.. It can also be designed according to the characteristics of the product. [1]

Implementation standard: China's container bag standard: the implementation of GB/T10454-2000, which is modified in the old standard GB/T 10454-1989, The Chinese container bag standard stipulates the classification structure, technical requirements and inspection requirements of container bags.

This standard applies to container bags with volume between (0.5-2.3) m3 and load capacity between (500-3000) kg.

British standard: bs6382

Australian standard: AS 3668-1989

European standard: EN1898-2000 and EN277-1995 European Container Bag Association standard: EFIBCA Standard

As3668-1989 refers to BS6382 standard, and the two are similar. The contents of ENL898-2000 and EFIBCA are roughly the same; Japanese standard JISZL651-1988 test items and China's container bag standard GBL0454-2000 is similar.

Process description: bags with polypropylene as the main raw material, add a small amount of the stability of the seasoning after mixing, the extruder melt extrusion plastic film, cut into silk, stretch, then through the heat setting made of high strength and low elongation PP, then through textile, drench membrane plastic woven cloth base cloth, and the harness fittings such as suture is made after tons of bags.
