Abstract:
The present invention relates to a lid film for packaging of e.g. human or pet food. The lid film has a multi-layer structure and comprises a sealing layer, a barrier layer, a print primer layer, a print layer, an optional print protection layer, and a relief layer. The sealing layer, the barrier layer, the print primer layer, the print layer and the optional print protection layer are essentially flat. The relief layer is arranged at least on a part of the print layer and comprises at least n three dimensional structures per cm2 projecting at an essentially right angle from a surface of the adjacent print layer or the optional print protection layer and said three dimensional structures forming an non-continuous elevated surface, wherein the total of said elevated surface area formed by the three dimensional structures equals at least m % of a total surface area of the lid film and wherein the three dimensional structures have a minimal height of 5 μm.
