Description

Technical Field

[0001] The utility model relates to the technical field of plastic bags, in particular to a breathable plastic bag. Background Art

[0002] Plastic bags play an indispensable role in our daily lives and are often used to carry other items. Plastic bags are cheap, light, have a large capacity, and are easy to store, so they are widely used. Ordinary plastic bags are mostly made of polyethylene film, which is not strong enough and has poor air permeability.

[0003] The utility model with announcement number CN221341944U discloses a plastic bag with good air permeability, including a main body structure and a sealing mechanism arranged on the top of the main body structure. The main body structure includes: a bag body, a reinforcement ring arranged at the bottom of the bag body, a reinforcement sheet arranged at the top of the reinforcement ring, silicone strips arranged on both sides of the top of the reinforcement ring, a water outlet ring arranged on one side of the bag body, a water outlet arranged inside the water outlet ring, a sealing ring arranged on one side of the water outlet ring, and a rubber ring arranged on one side of the sealing ring;

[0004] In the above technical solution, after the sealing ring is unscrewed from the thread on one side of the water outlet ring, the water inside the bag is discharged through the water outlet inside the water outlet ring, preventing the water inside the bag from being retained for a long time and causing the bag to rupture. The reinforcement ring at the bottom of the bag reinforces the bag, and the silicone strips on both sides of the top of the reinforcement ring disperse the force borne by the surface of the bag, further improving the load-bearing capacity of the bag. However, the breathable plastic belt is easily torn after long-term use, affecting the continuous use of filling things, and the overall toughness is not strong. Utility Model Content

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The utility model increases the overall structural stability of the bag body by arranging an inner membrane bag and a bag body in combination, and realizes ventilation inside the bag body with the cooperation of the first air vent and the second air vent. With the cooperation of multiple reinforcing belts, the stability of the bag body assembly is increased, and with the cooperation of the third air vent, the first air vent is connected to the outside world. At the same time, with the cooperation of the reinforcing belt, the edge of the first air hole on the bag body is limited to reduce the impact of tearing the first air hole on long-term use.

[0020] 2. The utility model sets a gauze to cooperate with the bag body, and opens corresponding through grooves on the inner membrane bag to accelerate the ventilation inside the bag body. The gauze intercepts objects inside the bag body to prevent the objects from falling and being affected. The handle strap with a circular groove is provided to help provide a fulcrum, which is convenient for the overall carrying and coordination. With the cooperation of the two limiting rings, the stability of the reinforcement belt combined with the outer wall of the bag body is increased, thereby increasing the overall toughness and extending the service life.
