The method includes the steps of: setting a fulcrum located at outer side of the object; setting a lift-off position on the film; and picking up the film from the lift-off position with the fulcrum as the axis, and applying a circular traction force with a variable radius on the film for peeling off the film from the object. The film peeling method can peel off the film covered on the surface of the object by different peeling stages, to reduce the peeling path and reduce the force required for peeling the film, thereby reducing the peeling time and improving the peeling efficiency.
