The invention discloses a pre-coating film with an aluminum-coated non-woven fabric or aluminum-coated cardboard substrate, which sequentially comprises, from top to bottom, a transparent coating A, a transparent coating B, an aluminum coating, a reinforced aluminum coating, a non-woven fabric or cardboard, a primer layer and a hot-melt adhesive layer. The thicknesses of the transparent coating A and the transparent coating B are both less than 400 angstroms, and the refractive index of the transparent coating A to visible light is lower than that of the transparent coating B. By coating the reinforced aluminum coating on the surface of the non-woven fabric or cardboard, the invention improves the fastness and toughness of the aluminum coating. Through the evaporation of two transparent coatings with different physical properties, the invention solves the problems of discoloration and darkening of the aluminum coating when printing or coating is performed on the non-woven fabric or cardboard after aluminum coating.
