The utility model discloses a recyclable bag which comprises a bag body, an opening of the bag body is fixedly provided with a sealing edge in a bendable mode, the sealing edge is provided with two first through holes which are symmetrically distributed, and one side, far away from the opening of the bag body, of the sealing edge is provided with a first pull
rope in a matched mode. The two ends of the first pull
rope penetrate through the first penetrating holes respectively and extend towards the opening of the bag body, limiting pieces are further fixedly arranged at the two ends of the first pull
rope, binding belts are fixedly arranged on the two sides of the bag body, and limiting openings allowing the limiting pieces to penetrate through are formed in the binding belts. According to the packing bag, after the sealing edge seals the opening of the bag body, the limiting piece penetrates through the limiting opening and then rebounds to abut against the binding belt, at the moment, the first pull rope is in an extension state, and the elastic force of the first pull rope can form pressure towards the bag body so that the sealing edge can be tightly pressed on the bag body; the situation that in the using process, the sealing edge automatically relieves the sealing state of the opening of the bag body, and consequently the articles fall or are stolen by unauthorized persons is avoided.
