A juice box, also called a carton (American English) or 'popper' (Australian English), is a small container used to conveniently carry and consume drinks (often squash, BrE). They are frequently made of paperboard with an aluminum foil lining, but variations exist. Juice boxes are most popular with children, although other uses include emergency drinking water, milk and wine. In 1989, environmentalists raised concerns that the multi-layered design of juice boxes made them difficult to recycle or reuse.
