To provide a gusset bag having a high impact resistance, particularly a high drop resistance.SOLUTION: A gusset bag is composed of a bag forming laminate 10 having at least a base material layer 1, a first adhesive resin layer 2, and a sealant layer 7 in this order. The sealant layer 7 is disposed so as to face the inside of the gusset bag, and the sealant layer 7 is a linear low density polyethylene layer having a loss tangent at 70°C of 0.20 or less and 110°C of 0.40 or more and 0.80 or less measured according to a tensile vibration-antiresonance method of JIS K7244.SELECTED DRAWING: Figure 1 【課題】高度の耐衝撃性、特に高度の落下耐性を有する、ガセット袋を提供すること。【解決手段】少なくとも、基材層１、第１の接着樹脂層２、及びシーラント層７をこの順に有する袋形成用積層体１０から構成されているガセット袋であって、シーラント層７は、ガセット袋の内側に向くように配置されており、かつシーラント層７は、ＪＩＳ Ｋ７２４４の引張振動−非共振法に準拠して測定した損失正接の、７０℃における測定値が０．２０以下であり、１１０℃における測定値が０．４０以上０．８０以下である、直鎖低密度ポリエチレンの層である、ガセット袋。【選択図】図１
