A method and machine for vacuum packaging a product, wherein a film tube (102) is generated, and, in the film tube (102), a product (P) is introduced and at least one cut is made. In the method, a vacuum is also applied inside the film tube (102), and a transverse seal is formed therein, a film tube (102) closed at one end being obtained upstream of the cut and a package closed at both ends being obtained downstream. Furthermore, the film tube (102) is transversely pinched, a portion the inside of which is isolated from the inside of the rest of the film tube (102) being obtained, and a chamber is demarcated around at least part of said portion, the vacuum being applied and the transverse sealing operation being performed inside said chamber. |
