Polymeric multilayer optical films, and laminate bodies that include such films, are cut or subdivided into one or more discrete pieces by removably applying a first and second liner to opposed major surfaces of the multilayer optical film. Laser radiation is then directed at the multilayer optical film through the first liner in such a way as to produce cut lines that define a plurality of pieces of the first liner and of the multilayer optical film. Thereafter, the plurality of pieces of the first liner are removed from the plurality of pieces of the multilayer optical film while the pieces of multilayer optical film are supported by the second liner. Application of the first liner to the multilayer optical film can be accomplished with electrostatics.
