The invention concerns a foil for covering goods carriers such that they can be handled more securely, so replacing the known aluminium cover foils. The foil comprises a plastics matrix which contains a particulate filler, the filler being selected and present in the matrix in such a quantity that the resistance to piercing of the foil is reduced to a limit of less than 450 N/mm (measured on an approximately 150 mu m thick foil). A highly crystalline polypropylene is used as the plastics matrix material.
