  • Patent number: 7640717
    Abstract: The invention relates to a counter element (22) being adapted to apply a pressure to a first portion of a packaging material in association with heating of the packaging material in order to seal the first portion of the packaging material to a second portion of the packaging material. The element (22) being provided with an abutment surface (23) adapted to at least abut said first portion of the packaging material. The abutment surface (23) is provided with a plurality of indentations (24) adapted to entrap fluid or gas present in the vicinity of the abutment surface (23) and the first portion of the packaging material. The inventions also relates to a method of providing a counter element (22) as described above.
