A method for producing an alveolar panel element particularly for coverings, packagings and supporting surfaces, comprising the steps of extruding a first layer and a second layer of thermoplastic material, shaping the first and second layers so as to provide, on each layer, a sheet-like element with elements that protrude on at least one face, and coupling the protruding elements of each layer in order to obtain an alveolar panel element.
