Common webs include foil, metal, paper, textile, plastic film, and wire.
Common processes carried out on webs include coating, plating, and laminating.
Between processing stages, webs are stored and transported as rolls also known as coils, packages and doffs.
Webs, being continuous, can be made at far higher speeds and do not have the start-stop issues of discrete sheet processing.
Web processing is found in a wide variety of other manufacturing including electronics such as circuit boards, construction materials such as roofing, and pharmaceuticals such as drug patches.
