<P>PROBLEM TO BE SOLVED: To provide a package bag allowing steam generated therein at heating to escape as planed through a given part, and a package provided by sealing a content article in the packaging bag. <P>SOLUTION: The package 1 includes the packaging bag 2, and the content article 5 stored in the packaging bag 2. The packaging bag 2 has a rectangular body film 3, a seal band 8 sealing the outer edge of the body film 3 in a band-like manner, and a storage portion 4 encircled by the body film 3 in which the content article 5 can be sealed. The seal band 8 has an outer edge seal portion 9 encircling the storage portion 4, and a steam ventilation portion 10 which bends from the outer edge seal portion 9 toward the storage portion 4 to project with a corner 10a formed closer to the storage portion 4. The location of the corner 10a of the steam ventilation portion 10 is so determined that a distance from the center A of the storage portion 4 to the corner 10a is shorter than that to the outer edge seal portion 9. <P>COPYRIGHT: (C)2008,JPO&INPIT |
