[0002] Container bags that combine inner and outer bags are usually used to transport bulk goods, such as powdered materials, granular materials or liquids. The main function of this design is to provide additional protection and safeguards to ensure that the goods are not damaged or leaked during transportation. In general, container bags that combine inner and outer bags provide higher safety and security through the double protection of the inner and outer layers, and are suitable for various types of bulk cargo transportation.

[0003] The shortcomings of existing container bags are that the inner bags are mostly straight-through type. Since they are larger than the outer bags, they are prone to wrinkles during use. When loading and unloading, the products are torn and damaged, and the inner bags will be unloaded from the outer bags along with the materials, causing contamination of the contents. Existing container bags are all equipped with slings, which are used for loading and unloading on vehicles. If the slings are worn or broken after long-term use, the entire container bag cannot be used any longer, which affects its service life and increases its cost. Utility Model Content

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This container bag is based on the original straight-through inner bag and is cut and heat-sealed to change the straight-through shape into a shape similar to the outer bag. The inner and outer bags are easier to fit together when loading and unloading goods. A circle of burrs is cut and heat-sealed at the bottom / lid position, and is sewn to the outer bag with burrs or corner tape. The inner bag and outer bag are fixed together. During loading and unloading, the inner bag is connected to the outer bag and will not flow out of the bag with the contents. Because the inner and outer bags are fixed together and fit together well, there are no large wrinkles in the inner bag during loading and unloading, and no tearing or damage will occur. This container bag is provided with a bottom groove at the bottom. When the sling is worn or broken, personnel can also use a forklift to pick up the container bag for loading and unloading goods, making it more applicable and avoiding the increase in usage costs caused by the container bag being discarded.
