       7 . The machine according to  claim 1 , characterized in that said longitudinal closing device ( 23 ) is a welder suitable for optionally effecting the longitudinal welding between said bags ( 101 ). 
   
   
       8 . The machine according to  claim 1 , characterized in that it comprises a further longitudinal welder ( 24 ) positioned laterally for the welding with a side trimming of an excess ( 106 ) of film ( 12 ) and the closing of said packaging ( 100 ). 
   
   
       9 . The machine according to  claim 1 , characterized in that it comprises an overturning device with a belt ( 27 ) for the superimposition of said two bags ( 101 ). 
   
   
       10 . The machine according to  claim 1 , characterized in that said packaging station ( 20 ) comprises at least one labelling machine ( 22 ) situated along the unwinding run of the packaging film ( 12 ) for the application of labels ( 103 ) in pre-established positions. 
   
   
       11 . The machine according to  claim 10 , characterized in that said at least one labelling machine ( 22 ) is associated with a perforating device for the perforation of the film ( 12 ) in correspondence with said labels ( 103 ). 
   
   
       12 . A packaging ( 100 ) for a series of editorial products ( 11 ,  11 ′), characterized in that it comprises two parallel bags ( 101 ) closed and separate from each other for at least one first main product ( 11 ) and for at least a second product ( 11 ′), respectively. 
   
   
       13 . The packaging according to  claim 12 , characterized in that said two bags ( 101 ) can be folded along an intermediate closing line ( 104 ) for the presentation of four distinct display sides for a greater visibility of the packaged products ( 11 ,  11 ′).
