The utility model discloses can prevent effectively that the powder of collection dress from sewing up the hole or sewing up the seam and leaking to the external world, can also make the flexible container keep square or tubular structure after filling with the material, do not produce the bulge phenomenon, more be favorable to depositing of full-load flexible container.
Description
Technical Field
The utility model belongs to the technical field of the flexible container, especially, relate to a prevent leaking, flexible container of swell.
Background
The flexible container bag is a flexible container bag, also called large bag and ton bag, and is a flexible and bendable container, which is a large-volume transport bag made of foldable rubberized fabric, resin processing fabric and other flexible materials. The polypropylene or polyethylene is generally used as a main raw material, and is formed by extrusion film forming, cutting, wire drawing, weaving, cutting and sewing. The package is not only beneficial to improving the loading and unloading efficiency, is especially suitable for the package of the bulk powder and granular goods, is beneficial to promoting the normalization and serialization of the package of the bulk goods and reducing the transportation cost, but also has the advantages of convenient package, storage, low manufacturing cost and the like. The packaging bag is particularly suitable for mechanized operation, is an ideal choice for storage, packaging and transportation, and can be widely applied to the packaging of road, railway and marine transportation of bulk materials such as cement, chemical fertilizer, salt, sugar, chemical raw materials, ore and the like. Therefore, freight bags are widely used in various countries in the world in recent years for transporting powdery and granular goods. The appearance and use of bulk bags is a qualitative revolution in the manner of shipping granular goods.
All parts on the flexible freight bag are usually connected in a sewing mode, and when powder materials with small particle sizes are filled in the flexible freight bag, the small powder materials are easy to leak through sewing holes or sewing seams, so that the flexible freight bag not only affects the flexible freight effect, but also affects the storage environment. After some flexible freight bags are filled with materials, due to the extrusion of the materials, the middle parts of the flexible freight bags are very easy to form a drum bag shape, and the packaging and storage effects are influenced.
