Abstract
A composite thermoformed cassette album or cover is described in the style of a book having a front and rear cover with a connecting spine between them. The album is formed from a base or backing sheet of relatively stiff material which extends throughout the width and breadth of the front and rear covers and through the spine area. It includes a thermoformed tray on the rear cover to hold the cassette. Soft vinyl sheet material is laminated over the outside surface of the stiff plastic sheet. A soft front cover liner laminated to the inside of the front cover includes a medial spine extension that extends throught the spine area. The soft plastic encapsulates the ridged plastic in a 3 layer laminate throughtout a pair of parallel hinges thereby prolonging their life.
