Disclosed herein is an aerosol-generating article comprising an aerosol-generating material, which is heated during intended use to release an aerosol, but is not burnt, and a wrapping material. Therein, the wrapping material has a thickness of at least 50 μm and at most 350 μm, a basis weight of at least 50 g/m2 and at most 200 g/m2, a specific density of at least 500 kg/m3 and at most 1300 kg/m3, and a bending stiffness of at least 0.15 Nmm and at most 1.50 Nmm. The wrapping material further comprises at least two layers, wherein the layers are connected to each other and wherein one layer is a paper layer, which has a thickness of at least 40 μm and at most 70 μm, a basis weight of at least 50 g/m2 and at most 80 g/m2, and a density of at least 700 kg/m3 and at most 1300 kg/m3, and a specific density that is higher than the specific density of any of the other layers of the wrapping material.
