The present invention provides novel kind of aluminum laminally filled plastic pellets and a process and apparatus for manufacturing the plastic pellets. The process includes coating the upper and lower surfaces of each of the substantially parallel lined aluminum foil layers with a coupling agent; drying the aluminum foil layers; introducing a molten plastic matrix to the space between each two aluminum foil layers and the outer surfaces of the most outside two aluminum foil layers to moisturize and bind the aluminum foil layers; reducing the thickness of the aluminum foil layers to form a continuous laminally filled plastic composite plate; and cooling and cutting the composite plate into aluminum laminally filled plastic pellets of a predetermined size. The aluminum contained in the plastic pellet maintains a high aspect ratio, therefore, reducing the loading amount of the aluminum required to provide good EMI shielding of the plastic pellets, while not adversely affeting the mechanical properties of the EMI plastic product.
