Abstract: A laminate film has a composite structure and a bonding surface that eliminates the formation of air bubbles during the lamination process. A process for forming the laminate film includes spreading a PET film with an adhesive, drying the adhesive, and spreading a PE film, which is in a melted phase, on the dried adhesive, to form a composite film. An EVA fluid is spread on the PE film of the composite film, and the composite film with the EVA fluid is passed between first and second rollers. The first roller has a pockmarked surface and contacts the EVA fluid, thereby forming a pockmarked surface on the EVA fluid.
