Abstract
A dual roll laminating film cartridge refill for a reusable cartridge loadable in a laminating machine. The refill includes a first roll of continuous adhesive-coated translucent laminating film having a first axial end and a second axial end. The refill includes a second roll of continuous adhesive-coated translucent laminating film having a first axial end and a second axial end. A first connector couples the first axial ends of the first and second rolls at a predefined gap distance. A second connector is independent from and spaced from the first connector, the second connector coupling the second axial ends of the first and second rolls at the predefined gap distance. The first and second connectors are uniquely shaped and asymmetrical to provide a keyed interface to the reusable cartridge.
