The present invention refers to a paper article comprising a paper component having a first side and a second side, wherein the first side and/or the second side of the paper component is at least partially coated with a heat-sealable coating, wherein the heat-sealable coating comprises a first polymer comprising units derived from a (meth)acrylate and/or (meth)acrylic acid and/or a salt thereof, and a second polymer, being different from the first polymer, comprising units derived from a) a (meth)acrylate and/or (meth)acrylic acid and/or a salt thereof, and b) an alkene, wherein the first polymer and the second polymer are present in the heat-sealable coating in a weight ratio of 90:10 to 35:65, and wherein the first polymer and the second polymer are present in the heat-sealable coating in an overall amount of at least 50 wt. %, based on the total weight of the coating. Furthermore, the present invention refers to a laminate comprising a paper component, a substrate and a heat-seal layer being present between the paper component and the substrate, which is obtained by heat-sealing a paper article according to the present invention to the substrate. The invention also refers to a use of a coating for heat-sealing a paper component to a substrate.
