PACKAGING BAG

PROBLEM TO BE SOLVED: To provide a packaging bag that can be torn off along cutting lines by devising shapes of the cutting lines formed on both sides of the packaging bag and a combination.SOLUTION: The packaging bag is formed of a laminate having outer layers having left and right side edge thermal adhesion parts at opposing edges, an intermediate layer and an inner layer. At one outer layer of the laminate is formed a continuous first cutting line at the same position in a vertical direction as the left and right side edge thermal adhesion parts, which is parallel to the parts and has a starting point and an ending point at either a left or right outer edge in the parts, while at the other outer layer of the laminate is formed a continuous second cutting line at the same position in the vertical direction as the left and right side edge thermal adhesion parts, which is parallel to the parts and has a starting point and an ending point at either the left or right edge in the parts so as to differ in a formation position from the first cutting line in a planar view, so that a step is generated in a cut-off opening part when the bag is opened by being torn off in a lateral direction with the first cutting line and the second cutting line being starting points.SELECTED DRAWING: Figure 1 【課題】包装袋の表裏に形成する切目線の形状およびその組み合わせを工夫することにより、切目線から外れることなく引裂くことができる包装袋を提供することである。【解決手段】対向する端縁に左右端縁熱接着部を有する外層と中間層と内層とを有する積層体からなり、前記積層体の一方の外層に、左右端縁熱接着部に平行する上下方向の位置を同じくし、左右いずれかの外縁に起点と終点を有する連続する第１切目線を形成し、前記他方の外層に、左右端縁熱接着部に平行する上下方向の位置を同じくし、左右いずれかの外縁に起点と終点を有する連続する第２切目線を平面視で前記第１切目線と形成位置を異にして形成し、前記第１切目線と第２切目線から左右方向に引裂き開口した際に、引裂き開口部に段差を生じさせることを特徴とする包装袋。【選択図】 図１
