Digipaks are a type of CD packaging made of paper and cardboard with internal plastic segments to hold one or more discs. They are folded like a book and can contain additional materials like lyrics and photos. Digipaks became popular in the 2000s as an alternative to jewel cases and were originally owned by IMPAC Group, which was later acquired by various packaging companies. While less durable than jewel cases, digipaks are less likely to crack and are considered more environmentally friendly due to reduced plastic usage.
