PURPOSE:To provide an easy tearing laminated film excellent in easy tearing properties and linear cutting properties and also having sufficient strength and an easy tearing bag using this film. CONSTITUTION:In the case of an easy tearing laminated film, first-third layers 31-33 each containing nylon 6 (Ny 6) and m-xylyleneadipamide (MXD 6) are formed so that the Ny 6 content of the first and third layers 31,33 is set to 60-95 pts.wt. and the MXD 6 content thereof is set to 5-40 pts.wt. and the Ny 6 content of the second layer 32 is set to 40-85 pts.wt. and the MXD 6 content thereof is set to 15-60 pts.wt. The ratio of the first third layers 31-33 is set to 1:8:1-4:2:4 and the ratio of the first (or third) layer and the second layer is set to 1:8:2:1 and the ratio of the first and third layers is set to l:22:1 and, in this state, the first - third layers are stretched by 2.8 times or more in both of the MD and TD directions thereof to form an easy tearing film which is, in turn, formed as one layer of a plurality of layers. |
