Zusammenfassung:PROBLEM TO BE SOLVED: To guarantee the release of vapor at the time of heat expansion without lowering food protection properties. SOLUTION: A food packaging film 12 provided with an easily releasable weak bonding belt 20 forming a deaeration passage of almost the belt shape when the film is released partially is formed between a base film 14 and a sealant film 16. A weak bonding belt 20 is disposed at least on one site between a pair of peripheral edges facing each other so that the deaeration passage formed by releasing the film communicates with the outside of a bag 10, and the bag is manufactured by a heat seal 13 on the corresponding edges including respective terminals of the weak bonding belt after the sealant film 16 is disposed overlappingly on the inner face side.
