CONSTITUTION: A destructive film(10) includes a destructive layer(1) and a tackifier layer or an adhesive layer(2). Physical strength of the destructive film is less than the adhesive force of the tackifier layer or the adhesive layer to destruct the destructive film when removing the destructive film from objects.
