The base layer includes polypropylene and fillers. The interlayer includes a mixture or blend of two components I or II. Component I is a propylene homopolymer or a copolymer of .alpha.-olefins having 2 to 10 carbon atoms, or a terpolymer of .alpha.-olefins having 2 to 10 carbon atoms or a mixture or blend of said polymers. Component II is an HDPE or a blend of HDPE and a propylene homopolymer or a copolymer of .alpha.-olefins having 2 to 10 carbon atoms or a terpolymer having 2 to 10 carbon atoms. The outer layer essentially includes a propylene homopolymer or a copolymer of .alpha.-olefins having 2 to 10 carbon atoms or a terpolymer of .alpha.-olefins having 2 to 10 carbon atoms or a mixture or blend of said polymers.
