A label for covering gas exchange openings (3) comprises a top label (1) and a bottom label (7), which has a channel (5) system comprising at least one channel in the form of a recess (4). The channel system is permeable to gas on its bottom over at least a part of its area and is connected to at least one gas passage opening provided in the label. An independent claim is also included for manufacturing labels, each of the labels comprising a bottom label comprising channel structures, comprising: (A) providing a bottom label material web on a carrier web that is coated so that it repels adhesive; (B) stamping the channel structures forming a self-repeating, coherent pattern; (C) pulling off bottom label material which fills the channel structures as a lattice; and (D) applying top label material which covers the channel structure. |
