PROBLEM TO BE SOLVED: To prevent poor seal and poor appearance of a back-lining part due to a clearance between a vertical seal device and a film plane.SOLUTION: A device for manufacturing a packaging bag has a vertical seal device 120 which forms a back-lining part 3 which extends along a vertical direction and in which a pair of side edges of a film constituting a bag, which laterally face each other, are bonded in a principal rafter shape. The vertical seal device 120 comprises: a seal head part 121 which forms a vertical seal part 31 on an outer edge side of the back-lining part 3; and a guide head part 122 which is located on an inner edge side of the back-lining part 3 with respect to the seal head part 121 and which guides a non-seal part 32 formed on the inner edge side of the back-lining part 3.SELECTED DRAWING: Figure 1 【課題】縦シール装置とフィルム面の間隔に起因する背貼り部のシール不良や外観不良を防止する。【解決手段】本発明の包装用袋の製造装置は、袋を構成するフィルムの横方向に対向する一対の側縁同士が合掌状に貼着された、縦方向に沿って伸びる背貼り部３を形成する縦シール装置１２０を有し、該縦シール装置１２０は、前記背貼り部３の外縁側に縦シール部３１を形成するシールヘッド部１２１と、該シールヘッド１２１に対して前記背貼り部３の内縁側に配置され、前記背貼り部３の内縁側に形成される非シール部３２を案内する案内ヘッド部１２２と、を備える。【選択図】図１
