<p>Multilayer film material (22) for manufacturing a pipe-shaped body (21) of a tube (17). The film material (22) contains at least one barrier layer (10). The film material (22) is of thickness (d) extending from the outside (14) of the pipe-shaped body (21) to the inside of the same. At least one barrier layer (10) is arranged within a distance (a) of the inside (15) of the pipe-shaped body (21). The distance (a) represents 5 to 40% of the total thickness (d) representing 100%. The film material used on a tube exhibits therefore a barrier layer which lies close to the inside of the tube and hence also close to the contents of the tube. Volatile constituents of the tube contents are able to penetrate essentially only to the barrier layer and are not able to become concentrated in the other, thicker layers of the wall.</p> |
