context_page_description: A keg is a small barrel.
  Traditionally, a wooden keg is made by a cooper and used to transport items such as nails, gunpowder, and a variety of liquids.
  In recent times, a keg is often constructed of stainless steel. It is commonly used to store, transport, and serve beer. Other alcoholic or non-alcoholic drinks, carbonated or non-carbonated, may be housed in a keg as well. Carbonated drinks are generally kept under pressure in order to maintain carbon dioxide in solution, preventing the beverage from becoming flat.
context_section_description: One-way kegs, also known as disposable kegs or PET kegs, were invented in 1996. They are usually made of plastic. Some types have a cardboard outer packaging, which makes them easier to stack and transport, and also protects the plastic container. Some may use either bag in ball or spear technology. Products like the Hybrid keg have a puncture resistant wall and are easy to disassemble after use. Circular by design, the top and bottom chimes can either be re-used or recycled.
