PROBLEM TO BE SOLVED: To manufacture a bag body having a cut for tearing.SOLUTION: A method for manufacturing a bag body 1 having a cut 5 for tearing and/or a guide for tearing by use of a continuously transferred sheet 2 comprises a step at which a cut 5 for tearing and/or a guide for tearing is formed on a sheet 2 in the state that the sheet 2 is not folded up by use of first and second rollers 31, 32 which sandwich the sheet 2 continuously transferred in the state that the sheet 2 is not folded up and are rotated around an axis extending in a direction orthogonal to a transfer direction X of the sheet 2, and on an outer periphery of one roller 31 of which a cutting edge 31a is provided.SELECTED DRAWING: Figure 7 【課題】引き裂き用切り込みを有する袋体を効率良く製造する。【解決手段】連続して移送されるシート２を用いて、引き裂き用切り込み５及び／又は引き裂き用ガイドを有する袋体を製造する袋体１の製造方法は、連続して移送されるシート２を折り重ねられていない状態で挟持しかつシート２の移送方向Ｘと直交する方向に延びた軸回りに回転する第１及び第２のローラ３１，３２であって、一方のローラ３１の外周に切刃３１ａが設けられた第１及び第２のローラ３１，３２を用い、シート２が折り重ねられていない状態で２シートに前記引き裂き用切り込み５及び／又は前記引き裂き用ガイドを形成する段階を、備える。【選択図】図７
