Abstract
A body (1) of oriented thermoplastic 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) by pressing the film with a compression and heating element (50) and the necessary heat is supplied so that the film (2) will be fixed to the fixing layer (10). Since the film is bonded to substantially non-oriented plastic material, the desired detachability in the bond between the film and the material portion (1) is achieved.
