Method, machine and installation for vacuum packaging of products, where a plurality of individual bags closed at one end and open at the opposite end with at least one product therein are generated. For generating the bags, a transverse cut and a complete transverse seal on both sides of the transverse cut are made on the film tube, and a transverse cut without complete transverse seals on the sides thereof is made at a distance (L) substantially equal to the desired length of the bag to be generated from the transverse cut and seal on both sides. Each bag is oriented at 180 degrees with respect to the bag previously generated in the forward movement direction.
