Abstract: A method is disclosed for producing superior optically clear laminates having a sheet of semi-rigid material encapsulated in a thermoplastic interlayer between layers of rigid material such as glass. Pre-cooled laminate elements are assembled at reduced temperature, allowing positioning of the sheet of semi-rigid material in the interlayer of the assembly with minimal wrinkling, formation of air bubbles or entrapment of moisture. Thereafter, the laminate assembly is maintained under vacuum for an extended period of time, substantially eliminating wrinkling, air bubbles and moisture from between the laminate elements as well as pre-forming the semi-rigid sheet. Bonding heat and pressure is then applied, first heating the assembly to "tack" the laminate elements together, and next applying heat and pressure for bonding the laminate elements.
