To provide a laminate for a packaging bag, capable of improving transportability in a bag-making and filling machine, and to provide the packaging bag using the same.SOLUTION: A laminate 100 for a packaging bag has an external layer 1 and a sealant layer 2. In the laminate 100, a static friction coefficient of the sealant layers 2 is 0.55 or less; and a modulus of elasticity in tension of the sealant layer 2 in a width direction (TD direction) is 500.0 MPa or more.SELECTED DRAWING: Figure 1 【課題】製袋充填機における搬送性を向上することができる包装袋用積層体及びそれを用いた包装袋の提供。【解決手段】外層１及びシーラント層２を有する包装袋用積層体１００であって、シーラント層２同士の静摩擦係数が、０．５５以下であって、かつシーラント層２の幅方向（ＴＤ方向）の引張弾性率が、５００．０ＭＰａ以上である、積層体１００。【選択図】図１
