Abstract: Un método para sellar elementos (3, 4) de papel o cartón recubierto con plástico, el método consiste en unir los elementos a lo largo de la línea de sellado fundiendo el recubrimiento de plástico de por lo menos un elemento con rayos láser (11), el recubrimiento de plástico, cuando solidifica, genera la unión pegada de los elementos uno con el otro, caracterizado porque los elementos (3, 4) que se quieren sellar se sujetan en posición adyacente a la línea de sellado con el fin de mantener los elementos en posición fija durante el sellado y porque el sellado se realiza mediante un agente de sellado (7), que se mueve a lo largo de la línea de sellado y presiona los elementos para que se separen, con el fin de mantener abierto el punto de sellado, dirige los rayos láser (11) hacia el punto de sellado abierto para fundir el plástico y finalmente presiona los elementos uno contra otro para cerrar el sello.
