A
bin bag or
bin liner (
British English) or
garbage bag, or
trash bag (American English) is a disposable bag used to contain
rubbish (British English), or the North American equivalent trash or garbage. Such bags are useful to line the insides of
waste containers to prevent the insides of the receptacle from becoming coated in waste material. Most bags these days are made out of
plastic, and are typically black in color.
