PROBLEM TO BE SOLVED: To provide easily tearable laminate films of superior strength, superior oxygen gas barrier properties, and also superior tearability to be manipulated by hand and the like. SOLUTION: Easily tearable bags are manufactured by heat fusion bonding a polyester biaxially oriented film layer with an inorganic film layer of thickness of 25μm or less and provided with an inorganic film layer at least on one face, an aliphatic polyamide biaxially oriented film of thickness of 30μm or less and provided with the angle of extinction position (inclination of main axis) of 30 deg. or less and at least three sealant layers one another and also the sealant layers of the easily tearable laminate films one another. |
