[0004] Therefore, the utility model provides a waterproof and tough plastic bag to solve the above problems. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] The utility model provides a waterproof and tough plastic bag, aiming to solve the problem that the existing plastic bag is inconvenient to vent air and the like as mentioned in the background technology.

[0007] (II) Technical solution

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a waterproof and tough plastic bag, comprising a bag body and a buckle assembly arranged at the open end of the bag body, a polyethylene layer, a nylon layer and an aluminum foil layer are arranged on the bag body in sequence, an exhaust port is opened on the bag body, and a sealing mechanism is arranged on the bag body at the outer edge of the exhaust port.

[0009] Preferably, the sealing mechanism comprises a sealing sticker arranged at a position of the bag body below the exhaust port and a rubber-coated ring coated on the sealing sticker corresponding to the exhaust port.

[0010] Preferably, a reinforcement layer adapted to the rubber-coated ring is provided at the outer edge of the exhaust port.

[0011] Preferably, a pull tab is fixedly mounted on the rotating end of the sealing sticker.

[0012] (III) Beneficial effects

[0013] The waterproof and tough plastic bag has a simple structure and is easy to use. The application of waterproof materials such as polyethylene layer and aluminum foil layer effectively improves the waterproof performance and toughness of the plastic bag, protects the items in the bag from moisture and liquid, and is particularly suitable for products that are stored for a long time or have high waterproof requirements. The design of the sealing sticker makes it easy to operate the plastic bag when venting is required. By tearing off and re-adhering the sealing sticker, the vent can be sealed and reused, while keeping the freshness and dryness of the items in the bag. The application of the reinforcement layer avoids tearing of the bag body and enhances the sealing performance. BRIEF DESCRIPTION OF THE DRAWINGS
