Abstract
An air filling bag with an outer film strengthening structure includes two outer films and a main check valve, where the two outer films are adhered to each other to form an air chamber by means of hot sealing, in which each outer film includes the first film sheet and the second film sheet stacked together, and a plurality of first hot sealing lines is formed by adhering the first film sheet to the second film sheet by means of hot sealing in a first direction together with a plurality of second hot sealing lines formed by adhering the first film sheet to the second film sheet by means of hot sealing in a second direction. The main check valve is positioned between the two outer films and one end thereof projects from the air chamber. Air in the air chamber can compress the main check valve to shield a first air passageway of the main check valve so as to prevent air from leaking out of the air chamber after outside air flows in the air chamber via the first air passageway.
