Album Digipak Research

An album digipak is a form of packaging often used for album cover and in recent years its contents. It has been patented by the company AGI - Shorewood, a holdings company.

All about Digipaks
An album digipak would consist of the features such as:

Have a type of thick paperboard or card which would have been folded into a book style

Card outer binding, to bring the lyric sideline book together.

Two or more side trays which are capable of holding the CD to the case

Has a protective UV coating on the paper to ensure longevity and durability

The teeth of the packaging are brittle to allow the digipak to remain light.

In the diagram above, it shows the different sides of an album digipak and how it would fit around a CD.
The two end sides show where the CD would be placed and the little details such as the teeth and ridges that would be holding it in place.
These places would be see through as it would allow the accompanying leaflet to slot inside.
The accompanying leaflet would often consist of:
Notes of how the album first came together
A note from the artist themselves, often addressing their fans
The album track list
Lyrics to the singles that will be released
Contact details such as phone number, management, record company etc.
Sometimes it might be a photoshoot of the artist in the background of these spreads.

Some have even tried to make them recyclable by having them made out of renewable materials such as sugar cane and made ridges with the back packaging to get rid of the use of teeth.

Here some examples of digipaks that have become iconic to both the masses and in R&B.
