<p>According to the invention, by producing a packaging laminate (5) with an absorbent core layer (2) between an outer foil (1) and an inner foil (3), said latter foil (3) being one through which gas can permeate, in a simple manner there can be produced a packaging foil which can be used for the packaging of especially food products which emit gases and/or vapours, in that these will be absorbed in an effective manner by the core layer (2). The foil (5) can with advantage be produced by extrusion of the core layer (2), and by rolling of the foil layers (1, 3) and the core layer (2) in the formation of the packaging laminate (5). As absorption agent, Ca(OH)2 or CaO can be used for the absorption of CO2 and O2, and moisture.</p> |
