Description

Technical Field

[0002] Compared with small woven bags, container bags have the characteristics of large capacity, easy loading and unloading, labor saving, and improved efficiency. General container bags are sewn together, and during use, material leakage is easy to occur at the sewing parts. In addition, the slings on the bag are not strong enough and are easy to droop, which is inconvenient for loading and unloading of container bags and affects work.

[0003] The Chinese authorized patent document with the publication number CN214877175U discloses a moisture-proof and leak-proof composite container bag, including a flexible bag, the top of which is processed with a feed port, the four corners of the top of which are hot-pressed with handles, the flexible bag is composited by an inner liner, an outer liner and an interlayer, the outer wall of the inner liner fits the inner wall of the interlayer, the outer wall of the interlayer fits the inner wall of the outer liner, and the inner liner, outer liner and interlayer are hot-pressed and composited into one. The moisture-proof and leak-proof composite container bag realizes normal container operation through the cooperation of the flexible bag, the feed port and the handle, and effectively improves the moisture-proof and leak-proof ability through the composite design of the inner liner, outer liner and interlayer. When unloading is required, the sealing layer is punctured to allow the material to leak out through the puncture to realize unloading. After unloading, the sealing layer can be replaced to achieve reuse. Compared with conventional disposable container bags, this solution only needs to replace the sealing layer, saving production costs, simple use method and strong practicality.
