A structured packaging film is made by first of feeding a flat, unembossed first film web in a gravure printing device to a cylindrical print roller having an engraving on its surface with an array of cavities having a depth of at least 50 &#x3bc;m. Printing laquer is applied to the print roller to fill the cavities. Then the roller is rolled on the first film web to transfer the laquer to the web to form thereon a printed image in gravure printing. The laquer is dried on the web to have a thickness of at least 30 &#x3bc;m and the printed areas form clearly perceptible structuring.
