Abstract: Lids, for example, lids for machine-lidding of, e.g., beakers, dishes, menu dishes, goblets, small packages, etc., containing a substrate material featuring, with respect to a container on which the lids are used, a smooth outward facing surface bearing printing. On the inward facing side of the lid is a sealing layer deposited by extrusion laminate coating. The sealing layer exhibits on the free surface embossing with a depth of roughness of up to 50 &mgr;m. The embossing is transferred to the sealing layer in the form of a roughness pattern on the cooling roll on depositing the laminate coating of the substrate material and extruded sealing layer.

The extruded sealing layer on the substrate material exhibits embossing on the free side. If the lids are drawn from a stack of lids, for example, in a filing machine, the embossing allows them to be separated individually.
