Abstract
A system for bonding films includes a first film, a second film having a plurality of elements, a bonding roller, and a deformable roller having a deformable outer layer. The stiffness of the second film is less than that of the first film. By using the system, the deformable outer layer of the deformable roller produces enough deformation during bonding films to fill the area not covered by the plurality of elements on the second film. Therefore, the second film without sufficient stiffness and the first film can be bonded with each other to produce a composite film without wrinkles. A method for preparing a composite film using the system is also disclosed.
