Abstract:
The present invention is a self-standing bag (1) provided with a trunk section (10) having a cylindrically formed trunk member (10A), and a bottom section (12) formed by a half-folded bottom member (12A). Each of side ends of the bottom member (12A) are bonded to the inner surface of a back surface section (20) of the trunk section (10). The lower end of the bottom member (12A) is bonded to the lower end of the trunk section (10) over the entire circumference of the trunk section (10). Bonding films (22) for bonding the side ends of the bottom member (12A) and the trunk section (10) are layered on the trunk section (10) side of the bottom member (12A) so as to cover the entire bottom member (12A). Both side ends of the bonding films (22) protrude from both side ends of the bottom member (12A) in the width direction. Bonding of the side ends of the bottom member (12A) to the inner surface of the trunk section (10) is achieved by means of the bonding films (22).
