A new process is described for the production of polylaminate film (F) for packaging and the reel obtained, comprising the phases of unwinding (1) of an inner film (N) and an outer film (E), application (3) of adhesive substance (C) on the bonding surface of said inner film (N) and/or of said outer film (E), with the exception of localised areas (N1, E1); bonding (5) of said outer film (E) with said inner film (N) so that the respective said localised areas (E1, N1) are opposite each other, creation (6, 7) of one or more holes (N2, E2) on said inner film (N) and on said outer film (E), in each of said localised areas (N1, E1) and wherein said holes (N2) of said inner film (N) do not overlap said holes (E2) of said outer film (E); rewinding (8) of said polylaminate composite film (F) on a reel. |
