Perforation

A perforation is a small hole or series of holes punched or bored through a material or substance. This can serve various purposes, from creating points of separation like on postage stamps or toilet paper to facilitating ventilation, weakening a material for controlled tearing, or enabling access. The size, shape, and density of perforations can vary greatly, depending on their intended function. Often associated with damage or alteration to the surface of a material, they can be a deliberate design choice or a consequence of wear or failure. The process of creating perforations is also referred to as perforation.
