In order to prolong the durability of the sealing surfaces and to improve their stability in a heat-sealing device for bonding heat-sealable layers of paper or the like with each other, with a conveying device defining a transport path for the layers and a sealing device arranged along the transport path with at least one sealing jaw, it is suggested that the sealing jaw comprises a sealing surface facing the transport path, this sealing surface formed from 5 to 60 % of a wear-resistant, in particular abrasion-proof material and, in addition, of a material with good gliding properties.
