Abstract:
Provided is a process for manufacturing a glass/plastic laminate or a glass-less laminate having improved optical qualities. The process involves the use of a bi-layer film as a removable release liner. The bi-layer film comprises an inbound layer and an outbound layer. In the lamination process, the inbound layer is disposed adjacent to the plastic film outer layer and the outbound layer is disposed adjacent to a rigid cover plate. The polymeric material comprised in the outbound layer has a melting temperature that is higher than the temperature reached by the outbound layer in the lamination process. The melting temperature of the inbound layer is preferably at least 10 C. higher than the melting temperature of the outbound layer. Preferred bi-layer release liners include polyethylene/polypropylene films.
