A method for producing a re-closable container. The method includes sealing a lidding film (10) on the upper surface (6) of the peripheral flange (5) and on the upper surface (11) of the peripheral frame member (9). During the sealing step, the bridging elements (13) of the discontinuous die-cut line (12) are broken by displacing the peripheral frame member (9) by means of the seal tool to a lower level than the peripheral flange (5). When opening the container, the lidding film (10) is peeled off from the container body (1) but stays adhered to the peripheral frame member (9) of the lid (2). The container can easily be opened since the bridging elements (13) between the lid (2) and the container body (1) are broken during the heat sealing step.
