a method for forming a laminated product includes providing a film 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 ; feeding a polymer sheet to the nip point , 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 .
