Zusammenfassung:To provide a packaging bag which can form an easy-to-cut line itself and a pattern for guiding a consumer to the easy-to-cut line without locational deviation, and to provide a formation method of the easy-to-cut line.SOLUTION: A packaging bag is formed by a laminate 1 having a laser coloring layer 20 at least including a base material 10 and ink which develops a color by carbon dioxide gas laser irradiation and a sealant layer 40. An easy-to-cut line 3 is formed in which a coloring part 80 in which the laser coloring layer has developed a color and a fragile processing part 70 in which fragile processing is performed on a base material are overlapped with each other on the same line.SELECTED DRAWING: Figure 1 【課題】易カット線自体と、消費者を易カット線に誘導するための絵柄等を位置ずれなく形成することができる包装袋および易カット線の形成方法を提供する。【解決手段】少なくとも基材１０と炭酸ガスレーザー照射により発色するインクを含むレーザー発色層２０とシーラント層４０を有する積層体１で形成される包装袋であって、レーザー発色層が発色した発色部８０と、基材が脆弱加工された脆弱加工部７０が同一線上に重なった易カット線３が形成されてなることを特徴とする。【選択図】図１
