Abstract
A two-ply, book-style album (10) comprises an inside tray sheet (12) and an outside cover sheet (14). Sheets (12 and 14) are preferably formed of high-density polyethylene, and are thermally heat-sealed together by means of a peripheral seal (34) and spine rules (36). The spine rules (36) include longitudinal grooves (38) formed to a substantial depth into the front surface of the inside tray sheet (12) in order to define living hinges which provide a roundish, less square spine of more pleasing appearance.
