This invention discloses an easy-tear breathable bag, relating to the field of packaging technology. It includes a bag body, a self-sealing strip mechanism, a sealing film, and an elastic opening mechanism. The bag body comprises a first bag body and a second bag body. The adjacent perimeters of the first and second bag bodies are heat-sealed to form a storage cavity, within which several independent cavities are formed. A retrieval port is provided on the first bag body directly opposite one of the cavities. An elastic opening mechanism is located in the middle of the first and second bag bodies, with several retrieval ports located around the periphery of the elastic opening mechanism. A self-sealing strip mechanism is provided around each retrieval port. The sealing film is connected to the sealing strip mechanism, and the sealing strip mechanism is connected to the elastic opening mechanism. The easy-tear line and guide groove design on the sealing film make tearing the film easier and more precise, preventing excessive damage to the packaging due to careless tearing and improving the user experience.
