Abstract
Lids (10) of a substrate material (5) having a plastic film, featuring printing (6) on the outside, with respect to a container (1) on which the lid (10) is employed, and an inward facing sealing layer (8,9), for closing the container (1) which has a shoulder region (4). The inward facing side of the substrate material (5) features the sealing layer (8,9) in the form of a printed image, and the printed image corresponds with the shoulder region (4) of the container (1) and is in the form of a series of points (12). The printed image (12) which forms the sealing layer (8,9) and the printed pattern (12) may be deposited in the same printing machine in which the printing (6) on the substrate layer takes place. The printed image (11) enables easy removal of the lids (10) individually from a stack of lids in the packaging machine without having to depend on embossing of the lids.
