The invention discloses a reflective aluminum coiled tape for a motor vehicle license plate. The reflective aluminum coiled tape is of a layer structure which is mainly composed of an aluminum base layer, adhesive layers, a metal reflective layer (an aluminum powder layer or a PET aluminized film), a glass bead layer and a protective adhesive layer according to actual needs. The invention furtherdiscloses a production process of the reflective aluminum coiled tape for the motor vehicle license plate, wherein the production process comprises the steps of unwinding, oil removal, pure water cleaning, ash removal, pure water cleaning, bright dipping, pure water cleaning, sand blasting, anodic oxidation, coating of an adhesive layer A, spraying of the aluminum powder layer or bonding of the PET aluminized film, drying, coating of an adhesive layer B, spraying of the glass bead layer, drying, coating of the protective adhesive layer, drying and winding. The production process needs to be optimized and selected according to the actual layer structure of the product. The invention further discloses a reflective aluminum plate for the motor vehicle license plate. The reflective aluminum plate has the same layer structure as the reflective aluminum coiled tape. The reflective aluminum plate has the advantages of being low in production cost, beneficial to environmental protection, goodin product adaptability and wide in product application range.
