Corrugated and apertured web materials are disclosed. More specifically, the webs comprise alternating ridges and grooves, wherein apertures are located in the grooves. In one embodiment, a web comprises alternating ridges and grooves as well as alternating regions of lower basis weight and higher basis weight. The higher basis weight regions are located in the ridges and grooves and the lower basis weight regions are located in the sidewalls between the ridges and grooves. The higher basis weight regions located in the grooves comprise apertures. The apertures have greater open area than previous apertures in similar webs.
