PROBLEM TO BE SOLVED: To provide a packaging bag which can be more surely cut to open along a half-cut line.SOLUTION: A packaging bag 10 comprises: sealed parts 11 made by adhering peripheral edges of laminated films 12 and 13; a storage part 18 formed between the laminated films 12 and 13; and unsealing means 20 for unsealing the packaging bag 10. The unsealing means 20 has: a first half-cut line 21 which crosses linearly a space between easily unsealed/processed parts 24 of the laminated film 13; second and third half-cut lines 22 and 23 which are formed to bulge toward a lower end part 16 and an upper end part 17 respectively between the easily unsealed/processed parts 24 of the laminated film 12; and a pair of auxiliary half-cut lines 26 which sandwich parts of the second and third lines. An endpoint of the second half-cut line 22 and an endpoint of the third half-cut line 23 are positioned between the pair of auxiliary half-cut lines 26.SELECTED DRAWING: Figure 1 【課題】より確実にハーフカット線に沿って切り開くことが可能な包装袋を提供する。【解決手段】包装袋１０は、積層フィルム１２，１３の周縁を貼り合わせてなるシール部１１と、積層フィルム１２，１３の間に形成される収容部１８と、包装袋１０を開封するための開封手段２０を備える。開封手段２０は、積層フィルム１３の易開封加工部２４の間を直線状に横断する第１ハーフカット線２１と、積層フィルム１２の易開封加工部２４の間において、下端部１６側及び上端部１７側にそれぞれ膨らむように形成される第２ハーフカット線２２及び第３ハーフカット線２３と、これらの一部を挟む一対の補助ハーフカット線２６を有する。第２ハーフカット線２２の端点及び第３ハーフカット線２３の端点は、一対の補助ハーフカット線２６の間に位置する。【選択図】図１
