Abstract: An aluminum plastic film of a battery, includes a pit and a flanging. The pit is used for placing a battery core and has a bottom surface that is connected to a first side elevation and a second side elevation. The first side elevation and the second side elevation are connected to each other. A first lower arc chamfer is formed at the joint of the bottom surface and the first side elevation, and a second lower arc chamfer is formed at the joint of the bottom surface and the second side elevation. The flanging is located at the upper periphery rim of the pit and connected to the upper end of the side elevation. A first upper arc chamfer and a second upper arc chamfer are formed at the joints of the first side elevation and the flanging and of the second side elevation and the flanging.
