A digipack is a type of packaging for discs, like CDs and DVDs, that folds out like a book rather than opening like a conventional plastic case. It is made of card, not plastic, and holds a transparent disc tray. Digipacks are commonly used for special edition CDs and DVDs because they can hold multiple discs using fold-out panels. While digipack is a registered trademark, the term is now used generally for similar folding disc packaging styles.
