<p>Packaging material (20) with good gas barrier properties comprising a skeletal layer (21) and a gas barrier layer (22) of a material with low elasticity, e.g. Al foil, which is placed against one side of the skeletal layer and which is bound to the skeletal layer with the aid of an intermediate layer of binding agent (23). The layer of binding agent (23) consists of a compressible material, preferably an expanded or foamed polyolefine, which is arranged to compress with the aim of reducing the tensile strains acting on the Al foil when the material is shaped by folding during manufacture of the packaging. <IMAGE></p> |
