摘要： The present invention relates to a method for making airtight packages (100) made of flexible material that are configured to seal an environment inside the package with respect to an external environment, said packages (100) comprising a front panel (1), a back panel (2) and two side gussets (3, 4) provided at opposite ends of the front panel (1) and of the back panel (2) so as to connect the front panel (1) to the back panel (2). The method comprises a first step of folding a sheet (60) made of flexible material along two first fold lines (L1) which are mutually parallel so as to form a tubular element (61). Moreover, the method comprises a second step that consists in folding an end portion of the tubular element (61) along two second fold lines (L2) that are oblique with respect to the direction of the first fold lines (L1) so as to form an end portion of the tubular element (61) that has two triangular portions (6, 7) having two mutually parallel sides (8, 9) and having a distance between each other equal to twice a first predetermined distance (D1). In addition, the present invention also comprises a machine (200) which allows using such method and a package that can be made by means of such method and such machine.
