  • CONTINUOUS LAMINATION OF POLYMETHYLEMETHACRYLATE (PMMA) FILM IN THE MANUFACTURE OF A FRESNEL LENS
    Publication number: 20110011390
    Abstract: A method for forming a laminated product includes providing a film (2) having a first surface embossed with optical structures and an opposite second surface; guiding the film to a nip point of a pair of lamination rolls (5, 6); feeding a polymer sheet (4) to the nip point (7), wherein the polymer sheet has a surface temperature effective to enable thermal bonding between the polymer sheet and the film; and laminating the polymer sheet to the second surface of the film. The present process reduces the cost and environmental impact associated with laminating fresnel lens film to acrylic sheet versus existing industry technology.
