[0025] Example 1

[0026] like Figure 1-5 As shown, an environmentally friendly and degradable plastic woven bag includes a bag body 2, the inner side of the bag body 2 is provided with a waterproof film 1 and a screen inner bag 6 which are separated from each other, the waterproof film 1 and the bag body 2 are sewn or bonded as a whole, the screen inner bag 6 and the bag body 2 are detachably connected, a sealing structure 7 is provided at the bag opening of the bag body 2, the sealing structure 7 is located above the screen inner bag 6, a number of drainage holes 211 are provided at the bottom of the bag body 2, and the bag body 2, the waterproof film 1 and the screen inner bag 6 are all made of biodegradable materials.

[0027] When the woven bag is used to hold crops, the crops are placed in the mesh inner bag 6, and moisture on the surface of the crops leaks out of the mesh inner bag 6, slides down along the waterproof film 1 inside the bag body 2, and is discharged from the drainage holes 211 at the bottom, thereby preventing moisture from accumulating and causing the agricultural products to rot.

[0028] The sealing structure 7 can be a structure such as a zipper that can seal the bag opening.

[0029] Drainage areas 21 are respectively provided at two bottom corners of the bag body 2 , a number of drainage holes 211 are located in the drainage area 21 , and the drainage area 21 is filled with sponge 5 .

[0030] The drainage area 21 is a spacing area with through holes (for the moisture of agricultural products to pass through), which is arranged at the bottom corner of the bag body 2. The sponge 5 filled inside can fully absorb the moisture of the agricultural products, and then the moisture of the sponge 5 can be effectively discharged from the drainage hole 211 by hand squeezing.

[0031] A protruding structure 3 for drainage is provided at the bottom of the bag body 2 . The protruding structure 3 is fixed between the two drainage areas 21 and is located between the waterproof membrane 1 and the mesh inner bag 6 .

[0032] The raised structure 3 is a structure that is high in the middle and low at the periphery, and can effectively drain the water leaking from the inner bag 6 of the screen into the drainage area 21 so that the water is absorbed by the sponge 5 .

[0033] A first zipper rack 61 is provided at the opening of the mesh inner bag 6, a second zipper rack 11 is provided at the opening of the waterproof membrane 1, the second zipper rack 11 is slidably connected to a pull head 12, and the first zipper rack 61 and the second zipper rack 11 are detachably connected via the pull head 12.
