The Wikipedia has the following information about this codepoint:
A juice box, also called a carton (BrE) or popper (AuE), is a small container used to conveniently carry and consume drinks. 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.
A juice box is considered an aseptic container, meaning it is manufactured and filled under aseptic processing and requires no refrigeration or preservatives to remain germ-free.
