From doing research on Digpacks I have found that:
Digipacks are a type of CD packaging made out of card stock or other heavy paper/cardboard material. Digipacks can flip open like a book, or it can have three parts, so that one portion of the packaging opens to the right and one to the left, with the CD in the center portion
I have also found that the album artwork is very important to the sales of an album. This is evident by this quote from the website ‘Designbump’
A powerful photograph could be all it takes to increase an albums amount of sales
From doing some more research I have found that albums can be distinguished into five types depending on their art work. The source I found this from is http://www.denisdesigns.com/blog/2010/04/amazing-album-cover-art/

These album covers use edited and manipulated photos as their artwork.
This group of album covers feature art that looks like found objects with the band name and album name on it.
