A lid () for closing a cup () along a peripheral sealing edge () and a method for producing such a lid. The lid includes at least one aluminum film and an optionally multi-layered plastic layer which is co-extruded onto the aluminum film and has a closed predetermined tearing line (). The plastic layer is made of plastic based on polyethylene (PE) or plastic based on polypropylene (PP), and the predetermined tearing line is introduced into the plastic layer preferably by means of a COlaser. The predetermined tearing line () may be provided directly in the region of the sealing edge ().

The present invention pertains to a packaging element comprising a supporting material fitted, on its face turned opposite the package, with a layer presenting a marking area and, on its face turned to the package, with a rough surface coating. The coating roughness has a depth of 1 to 100 &mgr;m, which can be obtained by using granulous filling material. The rough surface packaging element is suited as a covering element, including for yoghurt, as well as in the production of labels for bottle finishes.

Method for the production of a compound foil as an endless strip, the compound foil to be processed in the form of rectangular blanks covering a width of the endless strip characterized in that two different foil strips, of which a first strip contains an aluminum foil (4) or a paper are drawn through a lamination machine with tractive forces to overcome friction losses in the machine, these tractive forces producing different elongations in said two different foil strips, that one of the endless strips is provided at one side surface with a binding agent over a connecting surface, which consists of several partial areas (3, 13) separated from each other, that the two strips are connected to each other while the both strips being elastically stretched to different elongations as the strips are drawn through the lamination machine whereby after the two foil strips coming back again to their non-stretched starting state, that surfaces of the blanks each have one central area and two margin areas (9, 12) bordering on two blanks surface margins extending both in the endless strip extension, with, in each instance, in those margin areas (9, 12 ) a first proportion defined by the connecting surface area divided by the margin area surface being significantly greater than a second proportion defined by the connecting surface at the central area divided by the central area surface and that in the margin areas (9, 12) of the blank surface the said first proportion is at most 75%.
