Exploration into digipack
Digipaks consist of a gatefold (book-style) paperboard or card stock outer binding, with one or more plastic trays capable of holding a CD or DVD attached to the inside.
Digipaks differ from jewel cases because of the materials used, Jewel cases are a hard shiny plastic, you place the cover inside the case and the following pictures are underneath where the CD is inserted. With a Digipak, the case is a hard card/cardboard and sometimes an extra side with additional information or a photograph promoting the CD. Digipaks promote new albums or give additional information compared to Jewel cases. However Jewel cases can sometimes include booklets with the additional information although this has become very uncommon.
