The film can include a polyolefin polymer and a plurality of particles. The film can include a width and length defining a surface. The method can further include stretching the film to provide a stretched film. Stretching the film can provide a plurality of voids in the stretched film. The method can additionally include providing a laser assembly. The method can include directing abeam of light from the laser assembly upon the surface of the web to cut or perforate the web in at least one location.

Methods and systems for cutting or perforating a web with a laser

A method of cutting a web structure that is utilized in the manufacture of an absorbent article. The method of cutting the web structure can employ a laser having a pulse mode of operation. In various embodiments, the frequency of the beam of radiation pulsed from the laser can be patterned to correspond to the material of the web structure. In various embodiments, the frequency of the beam of radiation pulsed from the laser can be patterned to correspond to the speed at which the web structure is moving and can change with any change in speed of the web structure movement.
