[0043] The utility model discloses a kind of polypropylene color woven bags, including woven bag body and the reinforcing structure of any one embodiment as above, and reinforcing structure is set on woven bag body, since the specific structure of woven bag body in polypropylene color woven bag refers to above-mentioned embodiment, at least have all beneficial effects brought by the technical scheme of above-mentioned embodiment, hereinafter will not be elaborated one by one.

[0044] The working principle of the above embodiment is:

[0045] (1) The bag body 1 is woven by colored polypropylene fiber, and the appearance of the bag body 1 is printed with different colored patterns to improve the visual aesthetic. In addition, different colored polypropylene fibers are flexibly used during weaving to create unique textures and designs. This technology not only upgrades the appearance of the bag body 1, but also allows for personalized weaving bags to be created as needed, greatly meeting the customization needs of users. Users can easily tighten or loosen the drawstring according to actual needs, which facilitates flexible loading and unloading of goods while maintaining the neat shape of the bag body 1. When the user needs to tighten the drawstring of the bag body 1, the lower pressing block 26 can be pressed down to move the upper pressing plate 23 downward. At this time, the return spring 25 and the telescopic rod 24 are in a stretched state. The sliders on both sides of the upper pressing plate 23 move in the inner cavity of the sliding groove, which can limit the movement of the upper pressing plate 23. Then, the drawstring 21 is pulled to the right side to shrink the opening of the bag body 1. The press block 26 is then released to adjust the drawstring to the appropriate tightness. The return spring 25 will shorten the telescopic rod 24, causing the upper pressing plate 23 to move upward and re-press the drawstring 21, thereby facilitating the transportation of goods in the bag body 1.

[0046] (2) To enhance the load-bearing capacity of the bag body 1, a reinforcing cloth 31 made of high-strength polypropylene material is added to the bottom of the bag body 1. The reinforcing cloth 31 is carefully sewn to the bottom of the bag body 1, which significantly enhances the wear resistance and load-bearing capacity of the bottom of the bag body 1. In particular, in the stress-intensive corner areas, reinforcing ribs 32 are designed to effectively strengthen the load-bearing structure by increasing the weaving density and number of layers of fibers, thereby improving the overall load-bearing capacity and extending the service life of the bag body 1.
