The invention discloses a packing film and a rewinding device. The packing film is provided with viscous areas and non-viscous areas alternately arranged; the adjacent viscous areas and non-viscous areas are connected through double-sided adhesive tape joints; and the viscous areas are provided with induction labels for braking packing equipment. The rewinding device comprises a base; the base isprovided with a left support column and a right support column; a left platform is arranged on the left support column; a right platform is arranged on the right support column; a slide base is arranged on the left platform; a left shaft sleeve capable of rotating around the center axis is mounted on the slide base; the base is provided with a first driving device for driving the slide base to move in the axial direction of the left shaft sleeve; the right platform is provided with a right shaft sleeve capable of rotating around the center axis and a second driving device for driving the rightshaft sleeve to rotate; and a rewinding roller is connected between the left shaft sleeve and the right shaft sleeve through a spline. The packing film can accurately brake the packing equipment, andcan quickly taken down the rewinding roller during producing of the packing film to greatly improve the production efficiency.
