ABSTRACT A material portion (1) of oriented material is converted through heating in an area adjoining one boundary surface of the material portion to a layer (10) of substantially non-oriented material. A film (2) is fixed to the fixing layer (10) in that the film is pressed with the help of compression and heating means (50) to the layer (10). Through the heat supply from the means (50) the necessary heat is supplied so that the film (2) will be fixed to the fixing layer (10). Owing to the film being bonded to substantially non- oriented plastic material, the detachability aimed at in the bond between the film and the material portion (1) is achieved.
