Abstract: A composite film for the production of receptacles, in particular tubes, is proposed, the outer layers (1, 3) of which consist of a sealable material and between them contain an intermediate layer (5) serving as a print carrier for a decorative imprint. The sealing layers (1, 3) are laminated against the intermediate layer (5). At least the sealing layer pointing outward in the receptacle consists of transparent material. Since the intermediate layer (5) does not have to assume any sealing tasks, it can be optimized from the standpoint of printability, this being beneficial to the quality of the imprint. The margins (21) of a cut-to-size film piece (23) of the composite film which are to be connected flush to form a tubular tube blank contain clearances (25) which run along the margins (21) and which are filled, during sealing, with a material, in particular sealable material, which bonds fixedly with the outer layers (1, 3). The mechanical strength of the flush seam can be improved in this way.
