Laminates and methods of making same

The device suitable for the optical piece is comprises at least one part glass layer is. The optical sheet comprising a non-metal multi-layer optical film; the non-metal multi-layer optical film with multiple cable layer, wherein can be used as the solar reflecting film (for example infrared radiation reflecting film). The multi-layer is at least one optical film peripheral edge full-automatic and approximately full or at least one lighter part of the hot welding and/or the groove by a are generated, so prevented from at least one is superposed with the multiple of optical film peripheral edge full-automatic and approximately full or the occurrence lighter or the illuminance radiation part of laminations. Editable of processing to at least one optical film, so when optical film to the glass part, at least optical film peripheral edge full-automatic and approximately full or at least a lighter part can be provided with a glass part are pressure corresponding part of optical sheet is reverse driving to wherein a shielding or approximately with extending.
