Abstract

A packaging bag having automatic pressure regulating function, in which a bottom side of bag is formed in a forked gusset, a first thin-film interposed seal part and a second thin-film interposed seal part are respectively provided on an upper end side and a lower end side of one chamber A of the fork, and the strength of the thin-film interposed seals is relatively smaller than the strength of the seal part of the bag where no thin film is interposed, steam is generated by the heating, the internal pressure is increased, and when the pressure reaches the prescribed value, the seal at the part of the first thin-film interposed seal part is first broken, and after a while, the seal of the part of the second thin-film interposed seal part is broken to relieve the pressure in the bag outside.
